Hi, There are some problems,when using gst-rtsp-server as the streaming server.I used real player as my streaming client.I got segmentation fault in gst-rtsp-server: i am pasting the log here RTSP request message 0x8a0ee44 request line: method: 'SETUP' uri: 'rtsp://<a href="http://10.0.0.112:8554/test.mp4/stream=1">10.0.0.112:8554/test.mp4/stream=1</a>' version: '1.0' headers: key: 'CSeq', value: '4' key: 'Transport', value: 'RTP/AVP/TCP;unicast;mode=play' key: 'User-Agent', value: 'RealMedia Player HelixDNAClient/10.0.1.338 (win32)' key: 'Session', value: 'magihnnmjbkrtpug' body: ** Message: client 0x8a6a4c0: received a request ** Message: watching session 0x8a9d8c8 RTSP response message 0xbfe32d8c status line: code: '200' reason: 'OK' version: '1.0' headers: key: 'CSeq', value: '4' key: 'Transport', value: 'RTP/AVP/TCP;unicast;mode="PLAY"' key: 'Server', value: 'GStreamer RTSP server' key: 'Session', value: 'magihnnmjbkrtpug' body: length 0 ** Message: client 0x8a6a4c0: sent a message with cseq 4 RTSP request message 0x8a0ee44 request line: method: 'SET_PARAMETER' uri: 'rtsp://<a href="http://10.0.0.112:8554/test.mp4">10.0.0.112:8554/test.mp4</a>' version: '1.0' headers: key: 'CSeq', value: '5' key: 'Subscribe', value: 'stream=0;rule=0,stream=0;rule=1,stream=1;rule=0,stream=1;rule=1' key: 'Session', value: 'magihnnmjbkrtpug' body: ** Message: client 0x8a6a4c0: received a request RTSP response message 0xbfe32c80 status line: code: '200' reason: 'OK' version: '1.0' headers: key: 'CSeq', value: '5' key: 'Server', value: 'GStreamer RTSP server' body: length 0 ** Message: client 0x8a6a4c0: sent a message with cseq 5 RTSP request message 0x8a0ee44 request line: method: 'PLAY' uri: 'rtsp://<a href="http://10.0.0.112:8554/test.mp4">10.0.0.112:8554/test.mp4</a>' version: '1.0' headers: key: 'CSeq', value: '6' key: 'User-Agent', value: 'RealMedia Player HelixDNAClient/10.0.1.338 (win32)' key: 'Session', value: 'magihnnmjbkrtpug' key: 'Range', value: 'npt=0-23.166000' key: 'Bandwidth', value: '524300' body: ** Message: client 0x8a6a4c0: received a request ** Message: seeking to 99:99:99.999999999 -

I've already add the capsfilter to fix the problem, but my app. should support many different types of sources, so I can't hard code the frame rate. Anyway, the videosink plays well with the decoder caps of framerate=100/1. I think it means videosink does not look at the caps to play the stream, but jpegenc or avimux does look at the framerate for recording. I've investigated source code, but I coudn't find where the 100/1 came from. The truth is that rtspsrc doesn't even care about "a=framerate..." field to create cap, and it seems like not a mandatory attribute. Anybody can tell me what how mp4vdepay or ffdec_mpeg4 sets frame rate? Thank you in advance! Justin Is there anybody who can judge that this is a bug or not?
