What's the right way to give video frame to application?

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

 



Hi,

I've also run into a similar problem, that pjsua media doesn't record 
the associated call_id in either the stream (audio) or vid_stream 
structures. For video I hacked it by passing the call_id in the 
pjmedia_vid_dev_param structure when creating the video device. For 
audio I hacked it in pjsua_aud_channel_update, when the audio stream is 
created, that's where you can associate the stream to a call.

Regards,

Bill
