[Live-devel] about openRTSP

No, that won't work, because MPEG Transport Streams are streamed (in 
RTP) 'as is', with audio and video multiplexed together.

>If I want to get only video data for transport streams, how can I do it?

You can't, unless you demultiplex video from the received Transport 
Stream, *after* you receive it.  (You would need to use something 
other than our software to do this.)

You would do this in "H264VideoFileSink.cpp".
