Can not decode incoming RTP packet

hi, all,
I wrote a simple RTSP client to contact an existing RTSP IP CAM, and take a conversation to the CAM: >> OPTIONS * RTSP/1.0 >> CSeq: 30 << RTSP/1.0 200 OK << CSeq: 30 << Public: DESCRIBE,SETUP,PLAY,OPTIONS,PAUSE,TEARDOWN >> DESCRIBE rtsp://myipcam/h264.sdp RTSP/1.0 >> CSeq: 31 << RTSP/1.0 200 OK << CSeq: 31 << Cache-Control: no-cache << Content-Length: 171 << Content-Type: application/sdp << x-Accept-Retransmit: our-retransmit << x-Accept-Dynamic-Rate: 1 << v=0 << m=video 0 RTP/AVP 96 << a=rtpmap:96 H264/90000 << a=control:trackID=1 << a=fmtp:96 packetization-mode=1;profile-level-id=428032;sprop-parameter-sets=Z0KAMukGCcg=,aM48gA== >> SETUP rtsp://myipcam/h264.sdp/trackID=1 RTSP/1.0 >> CSeq: 32 >> Transport: RTP/AVP;unicast;client_port=54962-54963 << RTSP/1.0 200 OK << CSeq: 32 << Cache-Control: no-cache << Session: 135514808124572 << Transport: RTP/AVP;unicast;client_port=-10574--10573;server_port=6970-6971 >> PLAY rtsp://myipcam/h264.sdp RTSP/1.0 >> CSeq: 33 >> Session: 135514808124572 >> Range: npt=0.000- << RTSP/1.0 200 OK << CSeq: 33 << Session: 135514808124572 << Range: npt=now- it works and now the RTSP IP CAM continuously streams packets to my local port number (#54962) but for some purpose I didn't create an UDP listener on port #54962, instead, I want to use gstreamer to playback the incoming video stream, the below is my command: gst-launch -v udpsrc port=54962 caps="application/x-rtp, media=video, clock-rate=90000, encoding-name=H264" ! rtph264depay ! decodebin2 ! ffmpegcolorspace ! autovideosink it works to receive the incoming packets, but error occurs at the decoding stage, ... ... 0:00:53.466058000 4272 019F78E8 ERROR ffmpeg .:0:: decode_slice_header error 0:00:53.468058000 4272 019F78E8 ERROR ffmpeg .:0:: no frame! 0:00:53.677070000 4272 019F78E8 ERROR ffmpeg .:0:: non-existing PPS referenced 0:00:53.680071000 4272 019F78E8 ERROR ffmpeg .:0:: non-existing PPS 0 referenced 0:00:53.682071000 4272 019F78E8 ERROR ffmpeg .:0:: decode_slice_header error 0:00:53.683071000 4272 019F78E8 ERROR ffmpeg .:0:: no frame! 0:00:53.685071000 4272 019F78E8 ERROR ffmpeg .:0:: non-existing PPS referenced 0:00:53.687071000 4272 019F78E8 ERROR ffmpeg .:0:: non-existing PPS 0 referenced 0:00:53.689071000 4272 019F78E8 ERROR ffmpeg .:0:: decode_slice_header error 0:00:53.691071000 4272 019F78E8 ERROR ffmpeg .:0:: no frame! ... ... can anyone helps?? -- Hsiao-heng Lu ------------------------------------------------------------------------------ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |

thanks for your reply,
it works now. gst-launch udpsrc port=54962 caps="application/x-rtp,media=video,clock-rate=90000,encoding-name=H264,profile-level-id=428032,sprop-parameter-sets=\"Z0KAMukGCcg\=,aM48gA\=\=\",payload=96" ! rtph264depay ! decodebin2 ! ffmpegcolorspace ! autovideosink -v 2010/5/18 Wim Taymans <[hidden email]>
