[Libav-user] reading in and making sense of dumped RTP data
Hi, I'm just starting my journey with libav API and I need some guidance about how to read a dump of interleved RTP/RTCP (RTP over TCP) data into ffmpeg and decode it (h264 Constrained).
I know I can do it via rtsp (there are examples of it) but the thing is that I need it outside RTSP session, and RTP data sen't directly and read via sdp in ffmpeg/ffplay/ffprobe is for some reason destroyed (loads of h264 decoding errors but strangely enough RTSP with RTP over UDP is fine...).
So I know the basic steps to get it done i.e.:
1) decompose the interleaved stream to RTP and RTCP
2) depacketize RTP and get h264 stream
3) decode the stream (well in my case I guess it suffices to copy and mux it to a container)
4) mux and output container.
Question is which api should I use to do these steps? I assume that there is no ready API to decompose interleaved data, but then other tools do it some way and I can't see where
