I am using linphone on my ARM board, i want to add hardware encoder and decoder in the mediastreamer2.

While, i am going through the mediastream2 src, i found out the following,

videostream.c , videoenc.c , videodec.c handling video related stuff.

Also, video_stream_start() and video_stream_stop() .

I am little bit confused, how the flow works between 2 connections,

encoding process:

codec choose depends upon BW -> encode the frame -> rtp send

decoding process:

rtp recv -> choose the codec -> decode the frame -> displaying it.

Also, how this entire flow continuously running and syncing with the application. is it running like thread.

Is MS Video ticker is responsible for that.

Thanks and Regards,
