iPod video 'connection' selection not taking effect   
Hi,

We recently updated to the MME/iPod v1.2.1 drivers (on an ARM LE platform). We used to be able to use the preference 
'connection/component/k' in the startup of io-fs-media in order to get the iPod Touch to use the component output. This 
no longer seems to take effect. After i start up the driver i've used the function mme_device_get_config() and the 
returned XML data structure says:

'<connection value="composite" valuetype="enum" modifiable="no" alternatives="none,composite,svideo,component"/>'

(see the attachement)
which clearly is not what i specified in my startup of io-fs-media:

io-fs-media -dipod,transport=usb:sconfig:busno=00:devno=01:audio=/dev/snd/ipod-00-01,pref=lineout/on/k:video/on/k:screen
/fit/k:format/ntsc/k:ratio/wide/k:connection/component/k:caption/off/r,darates=+,mount=/fs/ipod0,playback,acp=i2c:path=/
dev/i2c3,fnames=short

I've also tried this on an iPod Nano with the same behavior.

Is this no longer the preferred method of setting the preferences?

Hi Mark,

The 1.2.1 ipod driver requires a configuration file now, and by default it looks for /etc/ipod.cfg.  You can always 
specify your own using the following command.

# io-fs-media -dipod,config=/path/to/config/file

Regards,
Kevin

Hi Kevin,

Thank you for the reply.

I forgot to mention that i do have that file on my system as well (in the default location /etc/ipod.cfg). 
However, as far as i can tell this file is not used to set the analog video preferences. From the document mm_ipod_dev.
pdf included in 1.2.1 i can see that it has the following sections:
[accessory] -> (i'm using the default ones that were in the sample ipod.cfg file
[eaf] -> unused and left commented out
[timeouts] -> as per sample file ipod.cfg

Thanks,
Mark

Hi Mark,

Could you please contact technical support at QNX? I think we can probably
easily help you with this. You need to send them an ipod driver log.

We cannot easily support iPod technologies on the forum, since it is a
public place and much of the information is obtained under NDA (by both your
company and QNX).
