[FFmpeg-user] I have question about receiving rtsp interleaved from encoder

[Nikolay Boyko]

VLC can work with this stream however I don't like how vlc work with rtmp.
mplayer don't now not try it.
By tcpdump vlc works slightly different. It send setup as ffmeg does.

SETUP.rtsp://
192.168.1.84/0/trackID=0.RTSP/1.0..CSeq:.4..User-Agent:.LibVLC/1.1.9.(LIVE555.Streaming.Media.v2010.11.17)..Transport:.RTP/AVP/TCP;unicast;interleaved=0-1..
..

RTSP/1.0.200.OK..CSeq:.4..Server:.GrandStream.Rtsp.Server.V100R001..Session:.91042740;timeout=120..Transport:.RTP/AVP/TCP;unicast;interleaved=0-1;ssrc=55aaee0;mode="PLAY"..

SETUP.rtsp://
192.168.1.84/0/trackID=1.RTSP/1.0..CSeq:.5..User-Agent:.LibVLC/1.1.9.(LIVE555.Streaming.Media.v2010.11.17)..Transport:.RTP/AVP/TCP;unicast;interleaved=2-3..Session:.91042740
..

RTSP/1.0.200.OK..CSeq:.5..Server:.GrandStream.Rtsp.Server.V100R001..Session:.91042740;timeout=120..Transport:.RTP/AVP/TCP;unicast;interleaved=2-3;ssrc=55aaf60;mode="PLAY"..

and send PLAY doesn't try to setup trackID=2 and then streaming begin.

PLAY.rtsp://
192.168.1.84/0/.RTSP/1.0..CSeq:.6..User-Agent:.LibVLC/1.1.9.(LIVE555.Streaming.Media.v2010.11.17)..Session:.91042740..Range:.npt=0.000-..
..

ffmpeg don't send PLAY it try setup trackID=2 got unsupported transport and
exit.
