MmSetDefaultClock   
Hi,

I was trying to build my own graph using MME. 

The function MMSetDefaultClock giving me a link error :

(.text+0x3bc): undefined reference to `MmSetDefaultClock'

But all other functions are getting linked !
I am including libmmedia.so as a shared library. 

Can somebody help me with this ?

Thanks,
Arun

Re: MmSetDefaultClock   
You don't create a graph if you are using the MME.  MME talks to io-media
which in turn uses MMF to play back the content.  Do you have the MME
documentation?

Re: MmSetDefaultClock   
sorry,
What I meant is I am trying to create my own graph using the library. 
that's when I got the error. 

Thanks,
Arun

Re: MmSetDefaultClock   
MMF is not normally a customer-facing API.  Also, there should be no
reason to call that function.  What are you trying to accomplish?

Are you using Aviage, or the Blackberry NDK?

Re: MmSetDefaultClock   
I am trying to learn about the library using examples from QNX Neutrino, Multimedia Developer's guide. Specifically Ex: 
"playing MP3". I was learning to use the 

media reader, wave parser and audio writer to get playing a wave file. I assume this is all I need to play a wave file. 


io-audio is functional in my system and I am able to play wave files using the wave utility. I am trying to achieve the 
same functionality with MMF. But this function is giving me a linking error. 

Thanks,
Arun

Re: MmSetDefaultClock   
If you are using Aviage, MMF is not a customer-facing API.  Why have you
chosen that?  Is there something the MME is not able to do for you?

Re: MmSetDefaultClock   
No I wanted to have an understanding of the framework internally so that I can write my own player.

by commenting out MmSetDefaultClock, I am able to get the graph started 
but Mmstatus returns MM_STATUS_ERROR.

Is there anything else I need to consider for plying just a wave file. 

you help is reapply appreciated 

thanks,
arun

Re: MmSetDefaultClock   
As I said earlier.  MMF is not a customer-facing, or supported API for
Aviage.  Sorry.  If you want to play media using Aviage, please use the
MME.
