Regards, Gilles Gilles Roy 2013-03-20T14:14:01Z http://community.qnx.com/sf/go/post100040 Hello Everyone, I have created a "C Application" to play around with qdb and I have plan to use it in my actual project later. I am facing the following issue - "database get results api returns - Input/Output error". I copied the DB to local system and tried opening using SQLite Browser - "file is encrypted or is not a database" error. Logic implemented in Application 1) Connect to database 2) Insert an data 3) Operate on that data(SELECT) and get the results of that operation. I followed the same code in "QDB Examples" of QNX documentation. Please provide some guidance to go ahead. Kathirvel Kuppusamy 2013-03-20T14:09:56Z http://community.qnx.com/sf/go/post99205 I'm having trouble getting the webkit browser window to show in tandem with a embedded Flash interface as demonstrated in QNX-CAR VMware where the Flash based browser controls appear around the browser. In my flash based interface I can get the webkit browser to appear but it seems to completely overlay the Flash interface. The browser shows graphics, and can be controlled via pps control object. However the onscreen browser, with sized defined smaller than the screen, shows black in areas where I'd like Flash to show through. How can I get the browser to appear with Flash? Ralph Canapa 2013-02-11T16:48:53Z http://community.qnx.com/sf/go/post97804 Hi all! Here some problems when referring to QSA calls. - snd_pcm_plugin_params fails with error "invalid argument", though the pcm handle is valid and the snd_pcm_channel_params_t structure is initialized; - also, snd_pcm_plugin_params fails if the format is set to SND_PCM_SFMT_FLOAT_LE or SND_PCM_SFMT_FLOAT_BE; - snd_pcm_channel_status_t: the stime member is always to 0, though the time member in snd_pcm_channel_params_t is set to 1. Where can be the problem? Thank you very much! G. a g 2012-12-05T10:54:38Z http://community.qnx.com/sf/go/post96625 Hello Given the licensing restrictions and other agreements related to iPod, we are unable to discuss our implementation in public forums. Please go through your existing support contacts to discuss this and any other issues related to iPod. Regards, > Jim Gilderson 2012-10-25T14:08:16Z http://community.qnx.com/sf/go/post96617 Hello, I'm using the QNX Aviage Multimedia Interface for iPod 1.2.1 to control an iPod. To my knowledge (besides the Extended Interface Lingo) you can use the simple remote lingo to control an apple device using ContextButtonStatus-Commands (Play, Stop, Next Track etc.). Unfortunately the "ipod_smplrmt_button"-Command has no effect. Using a high verbose (=6) regarding the iPod driver I see, that the ContextButtonStatus-Command is correctly send to and acknowledged by the apple device. What's the trick to control the apple device using the "ipod_smplrmt_*" commands? Is it really possible to use the "ipod_smplrmt_*" commands to control the ipod as specified in the MFI? Or is the simple remote lingo supported by QNX restricted to iPod Out? To control the iPod by means of the extended interface is completely unproblematic.The procedure is simply 1. connecting to the apple device (ipod_connect()) 2. use the "ipod_smplrmt_button" command (for instance IPOD_BUTTON_CONTEXT_NEXT_TRACK [playback engine is not empty]). I'm looking forward that anybody can give me a hint. Andreas Kruschwitz 2012-10-25T12:36:36Z http://community.qnx.com/sf/go/post94521 Thank you. Back to coding now... :) Yuh-Fwu Guu 2012-07-30T18:05:59Z http://community.qnx.com/sf/go/post94519 Yes, your plan would work as long as your goal was to treat media from all USB sticks as if it was available in one tracksession. Note: you'll want to update your tracksession after files pass (1st pass) of the newly inserted mediastore is complete. -- Ryan J. Allen QNX Software Systems Ryan Allen 2012-07-30T17:21:01Z http://community.qnx.com/sf/go/post94518 Ryan, If I had only one USB stick inserted and created a track session using the following statement... select fid from library where msid in (select msid from mediastores where (mountpath="/fs/usb0" or mountpath="/fs/usb1" or mountpath="/fs/usb2" or mountpath="/fs/usb3") and available=1) I used to create a new track session when I detected any of the other USB sticks was inserted, my understanding now is that I can use the mme_trksessionview_update() to refresh the files in the track session and have new files included when any of the other USB was inserted or removed. So there is really no need to call mme_settrksession() anymore if all I needed are the files from any of those possible mediastores, is this correct? Thanks. Yuh-Fwu Guu 2012-07-30T17:17:41Z http://community.qnx.com/sf/go/post94516 Thank you Ryan, Off to write the code now. Yuh-Fwu Guu 2012-07-30T15:19:47Z http://community.qnx.com/sf/go/post94515 Yes, trksessionview_update will update the play order. It should not affect the currently playing fid. You should ensure that your playing fid remains in the tracksession. The fids themselves will not change by using this call. The position of the fid in the tracksession may change, and the random position of the fid in the tracksession will definitely change. -- Ryan J. Allen QNX Software Systems Ryan Allen 2012-07-30T15:10:46Z http://community.qnx.com/sf/go/post94514 Will calling mme_trksessionview_update() affects what's being played back at the time the call was made in any way (stops the file currently being playback, etc)? In the MME API documentation for mme_trksessionview_update(), it says... "For both library-based and file-based track sessions, a call to mme_trksessionview_update() refreshes the pseudo-random order of the tracks in the track session." Does it means the files (same file from USB_1 for example) will get a different fid, when USB_2 was inserted and mme_trksessionview_update() was called? Yuh-Fwu Guu 2012-07-30T14:56:22Z http://community.qnx.com/sf/go/post94513 MME will not automatically refresh the tracksession to include the new files. You will have to call mme_trksessionview_update() to have it re-run the query. After this the tracksession should contain tracks from both mediastores. If a user disconnects USB_1 (/fs/usb0) while playback is still occurring on that mediastore you will likely receive playback errors. MME will try to play additional tracks and will, most likely, hit the consecutive play error count limit and stop playback completely. You should have to update the tracksession query and re-issue the play command. How you handle ejections and insertions of mediastores will depend on how you want your product to behave. Some products will limit the scope of tracksessions to a single mediastore (only tracks from USB_1 or USB_2 but not both); other products will play files across a number of different connected mediastores. -- Ryan J. Allen QNX Software Systems Ryan Allen 2012-07-30T14:09:00Z http://community.qnx.com/sf/go/post94512 Hello, I have MME and MCD setup to detect mediastores on USB sticks, how do I handle mediastore addition and deletion due to the insertion and removal of the USB sticks during a library based track session playback? For example, when I have one USB inserted, and I am playing audio files from this USB with track session created using the following statement... select fid from library where msid in (select msid from mediastores where (mountpath="/fs/usb0" or mountpath="/fs/usb1") and available=1) The track session playback will contain only files from USB_1, which is mounted as /fs/usb0. Now, if I inserted a second USB stick, it will be mounted as /fs/usb1, will MME add the files from the second USB stick and let the playback continue to play files in USB_2 when all files from USB_1 have been played back? Thanks. Yuh-Fwu Guu 2012-07-30T13:59:36Z http://community.qnx.com/sf/go/post94394 Hi Robb, I will send you an e-mail. -- Ryan J.

Has any one tried setting this up with an IPOD. Any advice/ help in this regard is welcome. Regards (My apologies to those added in recipients in case this does not interest them.) Rohit Nair 2012-07-11T06:34:05Z http://community.qnx.com/sf/go/post93813 The software mixer (software PCM mixer) only exist on the playback side of the house, as its job is to mix multiple PCM stream into one that can be written to a singe audio device (since we are doing sample by sample modifications for the mix we added in software volume controls into this path). For capture the only gain/volume adjustments you can do depend on what the hardware codec exposes in terms of controls (there are not software volume controls on the capture path). You can use the mix_ctl utility to dump all of control groups and to make adjust to those groups.

Rohit Nair 2012-05-29T04:34:28Z http://community.qnx.com/sf/go/post91957 I'm not sure this scenario is handled by MCD. If MCD only processes the mount/umount functions when there is a callout, you could possibly implement your own custom callout, as described in the MCD docs. Your callout could talk to your external device to get the insertion state, or alternatively, maybe your callout does nothing and you keep writing the to insert/eject files. It is possible just having a callout will allow it to mount/unmount. Regards, Gilles Gilles Roy 2012-03-07T19:52:25Z http://community.qnx.com/sf/go/post91902 Hello QNX Developers, My needs perfectly described by "CD-changer controlled by external firmware" section of MCD documentation. I need to avoid using built-in CD_MEDIA_IOBLK MCD routine and report CD insertion/ejection events externally. However, when I do that, configured start/stop rules are NOT executed. MCD is executed with '-vvvv' CL option. From sloginfo, I can see that notifications are received by MCD: Jan 01 03:03:41.632.3 00023 00 /dev/cd0 media inserted Jan 01 03:03:52.597.3 00023 00 /dev/cd0 media ejected Implementation is really simple and is pretty much a copy-paste from official documentation. Suppose that it is OK, as MCD does indicate these reports in the log (in case of insertion, "/dev/cd0" is written to /dev/mcd/.insert, in case of ejection, write it to /dev/mcd/.eject) Snippet of my mcd.cfg : [/dev/cd*] Start Rule = MOUNT Stop Rule = UNMOUNT [MOUNT] Callout = MOUNT_FSYS Argument = /etc/mcd.mnt [UNMOUNT] Callout = UNMOUNT_FSYS Note : In case of I switch to built-in CD_MEDIA_IOBLK routine, MOUNT rule is executed and CD is mounted. (To do that, I only need to add following lines to [/dev/cd*] device entry) > Callout = CD_MEDIA_IOBLK > Argument = 1000,2000 > Priority = 11,10 Thank you!

There is currently no public API for accessing the media database. Things are in flux currently, but there are plans to publish an API for this once Universal Search is available on the device. In the meantime, unfortunately, you will have to scrape the directories under /accounts/1000/shared for files. Cheers, Sean Sean McVeigh 2011-10-24T21:35:55Z http://community.qnx.com/sf/go/post89575 Thank you Gilles, I tried query mediastore tables and got the info I needed. Regards, Guu Yuh-Fwu Guu 2011-10-24T16:00:56Z http://community.qnx.com/sf/go/post89569 You can query the MME mediastores tables in the database. Each mediastore has a state (active or unavailable) which will tell you if it is currently inserted or not. Alternatively, in your mme.conf, there is this setting: <!-- Controls whether or not devices are automatically detected by the MME. This is independent of synchronization. --> <!--<DeviceDetection enabled="true"/>--> If you uncomment the DeviceDetection and set it to false, I.e.: <DeviceDetection enabled="false" The MME, when it starts, won't monitor devices. Instead, once your app is running, you can connect to the MME, register for events and then issue mme_start_device_detection(), this way you won't miss any of the statechange events. Regards, Gilles Gilles Roy 2011-10-24T12:46:23Z http://community.qnx.com/sf/go/post89551 Hello, Is there a way to query mme how many media stores have already been detected and what their id's and states are? Our hardware has two USB ports and mcd can detect the presence of an USB stick in either of these two ports. It does not matter if the USB stick was inserted before or after power up. The USB stick gets mounted as /fs/usb0. Our client application registers for mme events and can detect when a USB stick was inserted thru these events "EVENT_MS_STATECHANGE", "EVENT_MS_SYNC_STARTED", ..., "EVENT_MS_DB_SYNC_COMPLETE", and "EVENT_SYNCCOMPLETE". These all worked fine when the USB stick was inserted after the client application has already started. I am able to determine, from the events received, the mediastore id and its state. The problem comes if the USB stick was inserted before power up, none of the events get captured by the client application because the client application started after mcd has already detected and mounted the USB stick. What can our client application do, when it starts, to discover mediastores that have already been detected by mcd? Thanks.

Regards, Daniel Daniel Endres 2011-02-16T14:13:21Z http://community.qnx.com/sf/go/post83207 Hi all, as you may remember we asked for an option to also mark drm-protected files as unplayable within the library-table. This is because we don't want the user to experience play errors due to drm-protected files. We don't want to play DRM-Protected files at all and therefore they will be grayed out in our HMI. Since there is no mme configuration mechanism, we've achieved this, by using the database trigger you've provided which toggles the playable-flag if an protected file is encountered during metadata-pass. The downside of the is that the playable flag of drm-protected files may change between Sync pass 1 and 2. The reason why I'm bringing this up again, is the error handling which I'm implementing right now. The bad case is a sd card which consists of "only" unplayable tracks. E.g. 80 files which are already known as unplayable to the mme. The sd-card was removed and extended by 10 new drm-protected files and 10 new corrupt files. The issue I'm struggling with right now is, that I need a mechanism to determine that they're now playable files at all. Counting the playFileErrors isn't an option since e.g. I don't know if I receive playErrors for the drm-files at all (dependes on the point in time where the playback happens. Before or after the db-trigger toggles the playable flag). My prefered way would be to fire a sql statement on every filePlayError which determines the state of the playable field within the library table (for the fids in the current tracksession). For this I need to rely on the fact that the library table is up2date when the mme fires the last filePlayError. Speaking of my example above: 80 Files were skipped automatically because they are already known as unplayable The 10 drm files were also skipped, since pass 2 was done when the playback attempt happend At the time the 9 corrupt files generated 9 playFileErrors and the tenth file returned with another playFileError a "select sum(playable) from library where <tracksession stmt>" would return 0, right? Or could it happen that 1 or another value may be returned instead? Or put differently, on a playFileError the playable column within the library table gets updated before the according playFileError is emitted? Thanks, Daniel Daniel Endres 2011-02-16T14:04:19Z http://community.qnx.com/sf/go/post83204 Daniel, This is a side-effect of a change we made to not count "known not-playable" files as play errors. But it is a bug--we missed this case. We will have to fix this. -- Ryan J. Allen QNX Software Systems Ryan Allen 2011-02-16T13:44:04Z http://community.qnx.com/sf/go/post83198 Hi all, I've just ran into an issue regarding the automatic skipping of already known unplayable tracks (just did a touch to create some files). In my use case i had a tracksession consisting of ONLY unplayable tracks. If I fire a 'mmecli play_extended offset 0' on this tracksession, the mme skips as assumed from track to track with the message: 'Skipping file because it is known to be not playable. fid=251, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//3empty.mp3' Unfortunately the mme doesn't recognize the end of the tracksession and therefore loops until forever. At this point the mme is unresponsive as well. So it's not possible to call a stop or any other command. There are eleven entries within my tracksession: Jan 01 01:26:04 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=249, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//1empty.mp3' Jan 01 01:26:04 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=250, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//2empty.mp3' Jan 01 01:26:05 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=251, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//3empty.mp3' Jan 01 01:26:05 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=252, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//4empty.mp3' Jan 01 01:26:05 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=253, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//5empty.mp3' Jan 01 01:26:05 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=254, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//6empty.mp3' Jan 01 01:26:05 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=255, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//7empty.mp3' Jan 01 01:26:05 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=246, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//8empty.mp3' Jan 01 01:26:05 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=247, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//10empty.mp3' Jan 01 01:26:05 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=248, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//11empty.mp3' Jan 01 01:26:05 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=249, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//1empty.mp3' Jan 01 01:26:06 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=250, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//2empty.mp3' Jan 01 01:26:06 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=251, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//3empty.mp3' Jan 01 01:26:06 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=252, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//4empty.mp3' Jan 01 01:26:06 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=253, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//5empty.mp3' Jan 01 01:26:06 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=254, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//6empty.mp3' Jan 01 01:26:06 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=255, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//7empty.mp3' Jan 01 01:26:06 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=246, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//8empty.mp3' Jan 01 01:26:06 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=247, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//10empty.mp3' Jan 01 01:26:07 5 27 0 MME:_play(3229): Skipping file because it is known to be not playable. fid=248, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error testing/only corrupt files//11empty.mp3' Hopefully this is easy to fix!?

We can talk specifics for your project directly. In general, if it is an io-audio capture device you'll use a similar snd: URL. You would have to know which capture device to use. Some io-audio drivers will setup a link from a "known" name to the capture device. For example, our iPod driver for io-audio has a "cap_name" argument for this. -- Ryan J.

During the sync no playlists were found. You make things more verbose during the sync to see exactly what is happening. During the file sync pass it will note files that would be flagged as playlists. If it doesn't find any then there is nothing to do during the 3rd pass sync.

Currently the iPod is connected to B-sample via serial connection and is charged. Starting io-fs-media with "poll" argument works fine also on the B-sample. A second question is: Where can i see debug output of io-fs-media? Adding "verbose=1" to arguments produces neither an output in sloginfo nor an output on std::out I have attached the mcd.conf and sloginfo output (mmecli set_debug 4 4) when attaching AND detaching the iPod afterwards.

Gilles Gilles Roy 2010-07-12T18:21:51Z http://community.qnx.com/sf/go/post59049 If I understand what you're asking for, the answer is no. The iPod does not indicate the path on the iPod where the playback engine comes from. If you ask the iPod to play a specific path then the MME can provide the information (for the first file that plays). After the iPod takes over playback the MME only really knows what is in the playback engine--not how the playback items got into the playback engine. -- Ryan J.

When I look at the code, it seems we won't send you the MME_EVENT_METADATA_INFO if you specified O_SYNC when you called mme_connect(). If you really want a syncrhonous call, you should pass in a buffer instead of passing NULL when you call mme_metadata_getinfo_*() API calls.

This event includes the XML description saying how many images there are, and a description of each message. You are not catching that event. You would need to add a new case statement for MME_EVENT_METADATA_INFO and then parse the XML and then invoke mme_metadata_load_image(). That would in turn generate the MME_EVENT_METADATA_IMGAGE you are looking for but not receiving. BTW, instead of parsing the XML, if you want a shortcut (for testing), you could instead each time you receive the MME_EVENT_METADATA_INFO just call mme_metadata_load_image() with an index of 0. As well, I'd say that adds complexity to use a NULL metadata pointer. You might want to just get the XML immediately instead of use it in an async manner.

We recently extended this API to ask the device if it is handling its own tracksession (ie, in the normal case, when a song finishes playing does it play the next song automatically). The old functionality was to assume that it was. It seems that the iPod driver you have doesn't support the API we added. This is fine, as the behaviour is the same. To avoid it you would need to update your iPod driver. For this you should talk to your appropriate QNX rep. -- Ryan J.

For video content you just need to check "/Videos/Video Playlists/~0". This will contain all videos on the iPod. Things like podcasts or audiobooks will end up in Music/Songs or Videos/Video Playlists/~0. As well, playlists are just lists of content already on the iPod, so they don't need their own explicit check. /Music/Songs is the contents of playlist 0 for audio (*all* audio content on the iPod). The "/Videos/Video Playlists/~0" folder is playlist 0 for Video, all video content on the iPod is there.

I don't think that you would even get a mountpoint without the certificate. Are you sure you are using a Zune and not a PlaysForSure device? Vadivel: Yes, we are using Zune device only. We have PFS device and it works fine. We are able browse (on zune device - same device) and able to see the album, artist, genre ..etc list. When we try to play particular file then we are getting 'Unsupported codec error'. Gills: I was looking for the output of "pidin arg". In your pidin_log.txt I don't get the info I was looking for. Vadivel: Please find the pidin_arg_log.txt' file as a attachment. Let me know if you any more information. Regards, Vadivel Vadivel Palanisamy 2010-06-21T17:47:37Z http://community.qnx.com/sf/go/post57202 The sync complete event does not contain this data. Properly, you should be running queries on the database to get these totals. You can do this via qdb's API. "select count(fid) from library where msid = X and ftype != 5" will give you files (the ftype 5 is the device fid) "select count(folderid) from folders where msid = X" will give you folders (including the root '/' folder) "select count(plid) from playlists where msid = X" will give you playlists Note that this gives you the totals for that mediastore, NOT the totals inserted/changed for that mediastore. For example, if you are syncing a mediastore for the first time and there are 10 files you would have 10 files added, and 10 files total. If you then add 2 files to this and resync you will have 2 files added and 12 files total. -- Ryan J.

Vadivel Palanisamy 2010-06-18T13:38:15Z http://community.qnx.com/sf/go/post57116 Generally for iPod you will use a file-based tracksession. The iPod will fill-out a tracksession with other files in the folder you select. For example, if you create a file-based tracksession the first file in /Music/Songs/All/ the iPod will load all other items from the same folder into the playback engine. It will play the song you've selected first, but then it will play another one from that folder. The typical iPod tracksession is a file-based tracksession of only one item--the specific item that the user has selected. There are some exceptions to this general use. 1. If you sync the iPod to the library you can use library-based tracksessions. The same "autofill" of the playback engine mentioned above occurs, so you would generally only play one fid from the library and the iPod will carry on after that; 2. if you sync the iPod to the library AND use iPod stalked mode, you build library-based tracksessions with a list of the specific fids you want to play. Stalker mode has the MME specifically stop the iPod after each track has played, then the MME tells the iPod which song to play next. It's not perfect, but it is necessary if you want specific control over the playback order; 3. if you are resuming an iPod's playback using its existing playback engine (for example, when the user first connects the device), playback is usually done with the function mme_play_resume_msid(). This function automatically creates a library-based tracksession, though that is inconsequential to the caller. I'm not sure if iPod sync is in MME 1.2.1, and I don't think iPod stalker mode is. If you need either of these and don't have access to these features you'll have to talk to your QNX sales rep about a newer MME version. -- Ryan J. Allen QNX Software Systems Ryan Allen 2010-06-17T22:49:27Z http://community.qnx.com/sf/go/post57115 Thanks Ryan!

Vadivel Vadivel Palanisamy 2010-06-17T22:10:55Z http://community.qnx.com/sf/go/post57114 If you are synchronising a mediastore to the library then you can use a library-based tracksession. This builds a list of files to play by executing an sql query. An example using mmecli to play all media files from msid 7: mmecli newtrksession l "select fid from library where msid = 7 and ftype != 5;" If you will be exploring a mediastore (with the mme_explore_*() functions) you will get a list of files to play. For this you would use a file-based tracksession, adding the specific files you find that you want to play. -- Ryan J.

The one is to use the mme_explore_info_get() function with a previous call of mme_explore_position_set() with needed metadata_types set as flags. The other way is to refer to the nowplaying table of the qdb. What is the better way to get metadata-information from an iPod?

(The function returns no error) When calling mme_play(0) or mme_play_offset(0), no playback is started. The sloginfo reports the error: "Could not create graph..." see attached sloginfo.txt (the log-level was set to "mmecli set_debug 8 0" Thanks for any help.

Well, specifying the acp=i2c option tells the iPod driver if you have an authentication coprocessor or not. If you do have an auth chip you should use that option regardless of the transport being used (serial or USB). If you don't have an authentication coprocessor, you can still get playback with analog audio over a serial connection, so the authentication is really only mandatory for USB playback.

Yes, all will be freed when you call mme_explore_end(). The MME uses a single buffer that can contain information about multiple items (when you call info_get() the first time, it can transfer multiple items from the MME to the client lib and keep them cached). The next time you call info_get() it might not even result in a context switch to the MME, instead the information might already be in the cache in the client memory space. Of note, you should take what information you need from the result before calling the next info_get(), otherwise the first results memory could be reused and will no longer be valid.

You should put the number of how many info_get() calls you will make. For example, if on your HMI you display 5 items (but plan on reading 10, say 5 extra to handle a page down) you should pass in items = 10. It is treated as a hint, it allows the MME to optimize things in some situations for better performance.

No, I think you need to check it out with SVN. There is probably a way to use SVN with IDE as well to check out the source code. I actually build on the command line, and then export my build area and stage over CIFS/NFS. Then on the QNX target I mount this shared folder and run a script to set my environment (LD_LIBRARY_PATH and PATH) so that it uses those binaries. Then I have a script that starts all the multimedia binaries.

If the IDE is important to you, you can do a "host" install on Windows (i.e. IDE and tools) and install only the QNX runtime on an x86 machine or in a virtual machine. Then you do all of your compilation/building on Windows. You don't build the MM suite on Neutrino at all, you just run/debug your binaries there. The IDE gives you can easy way to move over the binaries and to launch/debug binaries from the Windows host into the QNX target.

However, for some reason it isn't creating the fourth symlink, only 3. I think you should track down which software is responsible for doing this and start the investigation there.

Seraph Varghese 2010-02-26T13:42:57Z http://community.qnx.com/sf/go/post48264 Hi I have to build a multimedia streaming application (non-commercial) to run on QNX RTOS. Since, it wouldn't be feasible for us to get a commercial license for the MM Suite, we are planning to build it from the source code released on the community website. The problem is that to build the latest version from the source code, I need QNX 6.4 or greater, but QNX SDP 6.4.x for Neutrino Hosts does not have the IDE. The evaluation version does contain the IDE but is licensed for 30 days only. One of the options I was considering was to install the SDP for Windows Hosts (which contains the IDE), build the MM suite on windows and then transfer it to QNX 6.3. Is this possible? What is the best way to get around this problem?

All of the items that are mounted for you all seem to be coming from the first usb stick which has 3 partitions. If you insert them in the opposite order, do you get one item mounted and 3 that aren't? I don't recognize the error message as the one you've listed and I just did a quick check and had 6 distinct usb keys found/mounted on my system. # qdbc -dmme "select msid,mountpath from mediastores" Rows: 9 Cols: 2 Names: +msid+mountpath+ 00000: |1|/dev/snd| 00001: |2|/dev/socket| 00002: |3|/media/drive| 00003: |4|/fs/usb2| 00004: |5|/fs/usb1| 00005: |6|/fs/usb0| 00006: |7|/fs/usb3| 00007: |8|/fs/usb4| 00008: |9|/fs/usb5| # mount /net/EAc4dd91.ott.qnx.com/dev/hd0t179 on / type qnx6 /net/EAc4dd91.ott.qnx.com/dev/umass6t12 on /fs/usb5 type dos (fat32) /net/EAc4dd91.ott.qnx.com/dev/umass5t11 on /fs/usb4 type dos (fat32) /net/EAc4dd91.ott.qnx.com/dev/umass4t4 on /fs/usb3 type dos (fat32) /net/EAc4dd91.ott.qnx.com/dev/umass1t11 on /fs/usb2 type dos (fat32) /net/EAc4dd91.ott.qnx.com/dev/umass3t11 on /fs/usb1 type dos (fat32) /net/EAc4dd91.ott.qnx.com/dev/umass2t11 on /fs/usb0 type dos (fat32) /net/EAc4dd91.ott.qnx.com/dev/blk/ram-0-alloc-0-tmp on /fs/tmpfs type tmp # qdbc -dmme "select * from slots" Rows: 20 Cols: 10 Names: +slotid+active+msid+multimsid+slottype+zoneid+max_lib_entries+delete_at_start+path+name+ 00000: |1|1|3|0|3|1|1000|0|/media/drive|HardDrive| 00001: |2|1|6|0|1|1|1000|0|/fs/usb0|USB| 00002: |3|1|5|0|1|1|1000|0|/fs/usb1|USB| 00003: |4|1|4|0|1|1|1000|0|/fs/usb2|USB| 00004: |5|1|7|0|1|1|1000|0|/fs/usb3|USB| 00005: |6|1|8|0|1|1|1000|0|/fs/usb4|USB| 00006: |7|1|9|0|1|1|1000|0|/fs/usb5|USB| 00007: |8|0|0|0|1|1|1000|0|/fs/usb6|USB| 00008: |9|0|0|0|1|1|1000|0|/fs/usb7|USB| 00013: |14|0|0|0|4|1|1000|0|/fs/ipod0|iPod| 00014: |15|0|0|0|4|1|1000|0|/fs/pfs0|PlaysForSure| 00018: |19|1|2|0|10|1|1000|0|/dev/socket|INTERNET| # Thanks, Peter Peter Martin 2010-02-24T18:58:24Z http://community.qnx.com/sf/go/post48196 Currently, our mme only allows 3 USB devices to be shown.

The iPods and certain USB keys are only working after connected with a powered USB hub, otherwise just fail to be recognized by the usb driver. It is most likely an hardware issue and we wonder whether there is a way on software side can help to identify the problem. Now the problematic hardware is not available and will get more info once it is ready again, thanks.

Can you clarify in which way the iPods "don't work"? Once the configuration of the iPod gets selected the device is then allowed to draw up to its full reported power usage. Is the iPod displaying an error on the screen, or is it failing in some other way? Which iPods (touches, iPhones, nano, classic) don't work? Does the output of sloginfo show anything when this occurs?

In the MME, we create a wrapper function which we pass the prepared statement ID into. If there is no prepared statement for this ID, it goes ahead and creates one (it will be reused next time the same ID is passed in). If we don't need to hold on the ID, we pass in a special ID called FREE_AFTER_USE and the wrapper function frees the prepared statement once it has the result. In general, I'd say always use prepared statements. We use them for almost everything in the MME, even sometimes statements we execute only once. The main benefit is that it also prevents issues with strings not being escaped properly (i.e. when using normal statements you have to take care to use %q and %Q properly, in some cases a %s is a mistake). qdb_statement() is more useful if you are building dynamic statements that are always different and that you run frequently. In those cases you might not want the overhead of preparing/executing/freeing a normal prepared statement.

It's not a number that's stored in the database, or in the result. The code (in services/qdb/lib/qdb.c:qdb_printmsg()) is: 496 for (row = 0; row < nrows; ++row) { 497 fprintf(fp, "%05d:\t", row); You cannot use that specific number to refer to a row in a table; you can use it to refer to an offset in a query (with something like the OFFSET keyword as Gilles mentioned), but that might not be what you want. (For example, if rows are added/changed/deleted that would modify your result set the offset into that result will change.)

Hi Florian, Say I wanted the 10th to 15th results from a union of other results. What I would try is: select id from (select ... union ... select ... etc) LIMIT 5 OFFSET 10; (fetch 5 results starting at offset 10) I'm not sure I fully understand what you need to accomplish, I hope this helps.

No there should be no other configuration needed. If you start the mme-generic process with -vvvv you should see in the logs all of the configuration values it sets.

I think the client application can do this. I suppose if your system is based on a state machine some might find it easier to delay device detection and process all of the events that come in when it is started? Nothing comes to mind that would *require* delayed device detection, all of the info is available in the mediastores table.

Nevertheless the MME still detects all the devices after setting it to 'false'. Is there any other parameter which has to be configured? Version: QNX Aviage Multimedia Suite 1.2 General Questions: - The autodetection has manally to be enabled only once during the startup? - Is there another mechanism to prevent the loss of events from the type MME_EVENT_MS_STATECHANGE? - Would you recommend to use/not to use the autodetection of the MME? - Could the client application already read information out of the table mediastores without getting a MME_EVENT_MS_STATECHANGE? Background: In some scenarios the MME could be started earlier than the component reading/handling the MME events. Thanks a lot, Sebastian Sebastian Kiesel 2010-02-04T13:07:45Z http://community.qnx.com/sf/go/post45931 QDB is a 100% utf-8 interface. If content is placed in there that isn't UTF-8 then it is a bug in the client code that put it in there. In this example MME is the client application and it does convert different string encodings into UTF-8. All of the MME's interfaces including the explorer interface are UTF-8 also.

Regards Mike Michael Irsiegler 2010-01-26T12:40:13Z http://community.qnx.com/sf/go/post45823 All applications in QNX are using UTF8 (including mme). Using utf-16 would likely be a large undertaking.

Thanks again. Regards Mike Michael Irsiegler 2010-01-19T09:02:08Z http://community.qnx.com/sf/go/post45433 Sorry, just further information. Maybe you don't care about libqdb_cldr.so at all, you just want ICU support in SQLite to do things like case insensitive matching, etc. You can also do this by building the ICU library for QNX. Then you can download and build an ICU extension from the sqlite.org website: http://www.sqlite.org/cvstrac/dir?d=sqlite/ext/icu Then, check out the sqlite3 source code from the foundry 27 Multimedia project and rebuild ti with "SQLITE_ENABLE_ICU" defined.

This means it won't be in the Aviage release, but here is a link to the foundry 27 release that should still work: http://community.qnx.com/integration/viewvc/viewvc.cgi/trunk/services/qdb/cldr/?root=multimedia&system=exsy1001 If you check out the multimedia source following the documentation in the multimedia project, you should be able to build it. > 2.

But using the sourcecode on foundry 27 (even though it is based on our trunk, QDB/Sqlite has not has any big changes since Aviage 1.2) you could build libqdb_cldr yourself, or use it as a base for a different collation algorithm. Regards, Gilles Gilles Roy 2010-01-18T19:29:01Z http://community.qnx.com/sf/go/post45404 Hello all, We would like to enable the mme support for setting the language for sorting data retrieved by SQL select statements. According to the mme config guide a library called libqdb_cldr.so is needed. We have a few questions regarding this library: 1. Where do we find this library? The guide says that it comes along with the files for language sorting included with the mme release but we could not find it. 2. Is this library based on standard ICU (as found on icu-project.org), if yes, what version? 3. Would it be possible to build our own libqdb_cldr using the latest official version of ICU? Thanks in advance. Best regards Mike Michael Irsiegler 2010-01-18T17:11:06Z http://community.qnx.com/sf/go/post43745 It looks like the MME doesn't know it is a 2wire device (a device that does its own playback, where audio and control have distinct channels). In the avrcpexample.c file, in the function avrcp_getinfo(), make sure the media/device section of the info.xml file is "AVRCP", not "AVRCPEXAMPLE": xmlbuf_add(xp, "device", "AVRCP"); If you take a look in services/mme/mss/mediafs2wire/mediafs2wire.c, in the function mss_mediafs2wire_probe() you will see the "Found device..." log message which is followed by comparing the device to some known 2wire devices, setting the rating appropriately. -- Ryan J.

Generally, when you have issues related to playback, you should start io-media-generic with -DD.

You could try using gdb or putting printfs() in there to see how far it goes. Could it be spinning in a loop (i.e. trying to parse options or something?) at priority 12? That would make the other software on the board running at priority 10 look unresponsive. You could also raise the priority of your shell so that it doesn't lock up so you can better debug the issue (i.e. see the output of pidin) Regards, Gilles Gilles Roy 2009-12-09T15:40:45Z http://community.qnx.com/sf/go/post43410 hello all I want Integrating Bluetooth audio devices into the MME, so i use the avrcpexample.

But when i tried to use the api snd_pcm_open_preferred with SND_PCM_OPEN_NONBLOCK or'ed with SND_PCM_OPEN_PLAYBACK i am getting some unusual behavier. Is it correctly implemented. ie: Almost all the threads in the system and in the application is stopped and audio is executed. Priority is also enabled in my process. But i thinks something is going wrong. Any idea? When i tried without SND_PCM_OPEN_NONBLOCK, i got it working fine, but continuous write onto the device is causing problem in my application. Algorithm: write the buffer; check whether underrun/overrun happend prepare the device again. play the remaining buffer. The above steps are happening in a thread. So these steps, when executed multiple times ( i don't know when the voice output to the actual device will get over,because there is no callback like windows waveout functionality), my application stops sending output. Is there any problem of writing a buffer into the device when it is still playing the buffer. I have no clue from application side. Please help?

With this you can specify an offset between 0 and N-1 where N is the number of tracks in your tracksession. Regards, Gilles Gilles Roy 2009-10-28T13:19:51Z http://community.qnx.com/sf/go/post40872 Hi all, we just stumbled over another issue: We're planning to redesign our current HMI such that in a browser view, it would allow the user to select individual entries or complete folder hierarchies for playback. This includes playlists which are traditionally represented as folders as well. It shall be permissible for the user to select a track multiple times, say he has a playlist "80s" and another one "Peter Gabriel" which he both selects - in both you find the song "Sledgehammer". When bringing this selection over into a flat tracksession (to be visualized as such), the intention is to have the track in there twice exactly as the user specified - otherwise it would be indeterministic for him which one the system removes. -> How to have a track in a tracksession multiple times while still allowing the customer to exactly select one occurance without picking the wrong offset within the playback order? Since mme_play only takes a fid and does not allow to alternatively specify a track's sequential id we currently don't see a way how to accomplish this. (as discussed before we're currently planning on sticking with library mode) Thanks, Thomas Thomas Junge 2009-10-28T13:12:54Z http://community.qnx.com/sf/go/post40869 Thanks Gilles, your proposal of using MsgReceivePulse to wait works. @Dan: I already had that part correct, it was just how to make it behave blocking rather than a busy-loop :-) Cheers, Thomas Thomas Junge 2009-10-28T12:36:49Z http://community.qnx.com/sf/go/post40834 Take a look at the mme_register_for_events( ) function which allows you to get notified when one or more events have been queued for you to recieve. You can also look at mmecli.c for an example. Dan Cardamore 2009-10-27T19:29:52Z http://community.qnx.com/sf/go/post40825 > I'm wondering how to best wait for MME events in my code using mme_get_event. > Is there a way to block until events are delivered or must I set up a timer as > outlined in the MME Dev Guide in ch. 2? In the latter case, how to identify a > suitable interval at which to trigger? If you call mme_get_event() and there is no event waiting, you get a false event back with type MME_EVENT_NONE. You can't just block on the call. The timer example is misleading, I don't think it is needed. If you talk about blocking, then you probably have a dedicated thread for event processing. In this case you can setup an event (say a pulse) and then register that event with the MME. Then the thread can just enter a loop where it call mme_get_event() until MME_EVENT_NONE is returned, then the thread waits in MsgReceivePulse until it gets a pulse from the MME. Note that the thread should have a dedicated mme connection since you can't shared handle mme_connect() returns among threads. Or rather, you can share it, but you can't have two threads call into the MME at once using the same mme handle. Regards, Gilles Gilles Roy 2009-10-27T18:10:34Z http://community.qnx.com/sf/go/post40822 Hi all, I'm wondering how to best wait for MME events in my code using mme_get_event. Is there a way to block until events are delivered or must I set up a timer as outlined in the MME Dev Guide in ch. 2? In the latter case, how to identify a suitable interval at which to trigger? Best regards, Thomas Thomas Junge 2009-10-27T17:54:20Z http://community.qnx.com/sf/go/post36365 What platform are you running on? Maybe you should also start io-media with -DD options and post the full sloginfo (i.e. without -m27). Regards, Gilles Gilles Roy 2009-08-20T13:06:30Z http://community.qnx.com/sf/go/post36355 Hmmm. Here is a bit more infor. I think when I pressed FF or REWIND, the io-media failed to start a DspStatusInfo thread, which it looks like waiting for the status from DSP to say buffer level is low. Since the DspStatusInfo never starts, therefore, the io-media ReaderTask just waits: with NB Status is EOF waiting for buffer to empty out. Help..... I have no clue how to fix it... Jasmine Fong 2009-08-20T04:17:11Z http://community.qnx.com/sf/go/post36350 Thanks for you reply. A track session was created and set correctly. In the log I took following your instruction, I have played 7 songs, and on track 8 with offset 7 is where I pressed the FF button and released it. After the song is complete. Time update continues, and mme didn't advance to next song. I can see io-media didn't give EOF like it used to.

Post the result of: sloginfo -t -m27 With the resulting logs we will be able to help you solve your issue. There isn't any configuration setting that would cause the MME to actually stop. If you let the MME play the song until the end, does the MME play the next song automatically (i.e. if you don't do a FF at all, the next song plays?). Regards, Gilles Gilles Roy 2009-08-20T00:12:55Z http://community.qnx.com/sf/go/post36332 Hello, I have a simple question. As long as our application mme_play_set_speed(5000), and mme stops playing next track, even though the FF sounded fine, and after release the FF button, our application set mme_play_set_speed(1000) correctly as well. Is there anything obviously wrong with the way we have configure the mme? Jasmine Fong 2009-08-19T21:47:53Z http://community.qnx.com/sf/go/post35951 Hi all, I am looking at a problem where my debugger doesnt seem to help. My target has a sound card that has to be shared by 2 applications. Hence, I am trying to open/close my DSP pcm channel using libasound calls. On spawning my app, I can successfully play audio tracks. Now, I stop playing the track, flush the audio and close the channel using XXXX() call. When I try to open the channel again I end up in a core dump. It happens when my fn() calls the snd_pcm_open(). The arguments do not seem to be corrupt. When can such a situation arise? Praveen Kumar(deleted) 2009-08-13T19:04:04Z http://community.qnx.com/sf/go/post31497 Hi Yin, I'd recommend asking this question in the BSP and Drivers forum. You can find that project here: http://community.qnx.com/sf/projects/bsp Dan Cardamore 2009-06-11T15:39:25Z http://community.qnx.com/sf/go/post31460 I am writing a QNX USB driver program. USB device is inserted into the PC. Device is detected by my driver. Now, I want to get the audio data from device by urb. firstly, I must check the status of the urb. I used the function: usbd_urb_status(urb, &ustatus, &receive_len) Parameter ustatus is stored the urb's status. Then I did what I wrote under: ① check the value of ustatus, ustatus: USBD_STATUS_CMP_ERR（The operation is complete, but an error occurred） ② check the returned value of the usbd_urb_status(),returned value is EIO（I/O error） So, my question is : what is the reason of EIO occurred PS: I think the data transfer got some error occurred, but I don't know what wrong with the data transfer. Thanks for your suggestion!! Yin Xingmin 2009-06-11T09:11:31Z http://community.qnx.com/sf/go/post28778 Hi Arif, This forum is for multimedia topics.

I am use QNX 6.2.1 sorry for my English :)) Arif Budiono 2009-05-06T08:59:47Z http://community.qnx.com/sf/go/post26334 Foundry is a site where we develop our product openly. For support of released product you should still be going through the normal QNX support channels such as standard support, or priority support. There aren't any plans currently to put old branches on foundry27. If you plan to upgrade to 1.2 in the near future, then you can use the 20.14 release as a preview of what is to come on May 21st.

We've seen the problem on repositories with just aac files as well as on mixed repositories with aac, wma, mp3 and wav files. Part of the problem is that I have _no_ album art and the memory usage is shooting up just because of the API call being made. Is the release product tagged in the repository so that I could go back and look at the code that is close to what I'm using to see if I can help you guys narrow this down? As far as I can tell the project was created post 1.1 release and doesn't contain the 1.1 code as it was for the release. Otherwise, I guess this will have to go the route of priority support to get a patch made for 1.1 since this additional memory allocation will quickly overflow our configuration. I'll also take this opportunity to comment that the new history/sync mechanism is kind of gross.

Am I mis-understanding what you are saying? From what I see in the repository, there is no cover function for the mme_getphoto() client call, though there is still an (unused?) header in main.h indicating that there should be a server side call. Thanks, Thomas Thomas Fletcher 2009-04-08T11:41:30Z http://community.qnx.com/sf/go/post26135 In 1.1 the art from MP3 files is fetched directly with MMF since the MME is linked against MMF for just artwork. This means you would need to look through the top layer of the MME (devctl.c and photo.c) to trace if there are leaks there. Failing that my guess is that the issue is in MMF, in which case you may want to try with different types of container formats to see if it is an MP3 or MPEG4 issue for example. The next release that we're working towards is 1.2. mme_getphoto( ) replaced with a much more robust image framework that offers the following features: * Metatadata for images. Find out how many images there are and other details such as their size and dimensions. * load images on demand. mme_getphoto( ) could only load the first image, 1.2 can load any image in a file that was looked up previously * large image support. 1.1 only supported images smaller than 64kb * image profiles and conversion so that you can have thumbnails created, or have all your images in JPEG format. Configurable and built on top of QNX's libimg library * image caching so that subsequent lookups don't have to go back to the device or parse the image You can find all this in the daily builds or source code posted on this project. Documentation is also included in the documentation section. Dan Cardamore 2009-04-06T20:16:42Z http://community.qnx.com/sf/go/post26102 I'm using version 1.1 and we're using mme_getphoto()/freephoto() and it looks to me that on an overnight run that the memory consumption for mme-generic is growing out of control (200M on a couple hundred files). I tried to chase it down through the source code in the MM project, but it appears that the next release is destined to not have an mme_getphoto call (does that mean the next version is 2.0?) so the backing code is likely significantly different too. Any hints on how to curb this consumption? I've attached a simple program. Check out the mme-generic memory before/after running it. Also, there is some dead photo code in: mme/clientlib/mme.c: struct mmphotobuf Thanks, Thomas --- Crank Software www.cranksoftware.com Thomas Fletcher 2009-04-06T17:35:23Z http://community.qnx.com/sf/go/post22623 The multimedia team is happy to share with you our source code for the multimedia project.
