Help, play_cb not reading frames quick enough

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I have pjsip running in uclibc on my nios2 platform. It seems that the audiodev 
I've implemented, based on alsa_dev.c, is not grabbing frames from the jitter 
buffer, via conference port, quick enough for play back. For every about 10 
frames received from the remote end, I'm reading only one frame from the jitter 
buffer. 


Initially I thought about giving my pb_cb thread a higher priority, but I don't 
think I'm able to set a higher priority for the thread.

Does anyone has any experience running pjsip on nios2 platform?

And what's the recommended way to match the playback rate with incoming audio 
for my case? For example should I need to modify the conference bridge to allow 
multiple frames to be read from the jitter buffer with every player call back?

I'd appreciate if anyone can point me to the right direction.

Thank you in advance.

Cheers,

Chiang
