The stream does work if I play it using ffplay. If I dump the raw stream with openRTSP (from http://www.live555.com/liveMedia) and then feed it to ffmpeg, it does work too. It only stops working if I use ffmpeg to receive directly the stream (so unfortunately I can't provide you with any video samples). Using git bisect, I managed to narrow down the revision where the bug started happening: version 2107009 is the last one that worked, while 3e1cf49 (and subsequent ones) don't work. Following a discussion in the mailing list, I tried removing ""&& has_decode_delay_been_guessed(st)"" from compute_pkt_fields() in libavformat/utils.c, in the current version, and it started working too. Below are console outputs, including command lines: Output of the current version: {{{ [paulo@webserver ffmpeg]$ ./ffmpeg -v 9 -loglevel 99 -rtsp_transport tcp -i rtsp://root:root@192.168.1.131:554/axis-media/media.amp?streamprofile=Media?tcp -vcodec copy -acodec copy -t 4 ../axis.mp4 ffmpeg version N-44400-g2de8877 Copyright (c) 2000-2012 the FFmpeg developers built on Sep 12 2012 22:25:21 with gcc 4.1.2 (GCC) 20080704 (Red Hat 4.1.2-50) configuration: --enable-encoder=libx264 --enable-libx264 --enable-runtime-cpudetect --enable-libmp3lame --enable-gpl --extra-cflags=-I/usr/local/include --extra-ldflags=-L/usr/local/lib libavutil 51. 72.100 / 51. 72.100 libavcodec 54. 55.100 / 54. 55.100 libavformat 54. 26.101 / 54. 26.101 libavdevice 54. 2.100 / 54. 2.100 libavfilter 3. 16.103 / 3. 16.103 libswscale 2. 1.101 / 2. 1.101 libswresample 0. 15.100 / 0. 15.100 libpostproc 52. 0.100 / 52. 0.100 [rtsp @ 0xa6d85e0] SDP: v=0 o=- 1288182959680264 1288182959680264 IN IP4 192.168.1.131 s=Media Presentation e=NONE c=IN IP4 0.0.0.0 b=AS:50000 t=0 0 a=control:rtsp://192.168.1.131:554/axis-media/media.amp?streamprofile=Media?tcp a=range:npt=0.000000- m=video 0 RTP/AVP 96 b=AS:50000 a=framerate:25.0 a=transform:1,0,0;0,1,0;0,0,1 a=control:rtsp://192.168.1.131:554/axis-media/media.amp/trackID=1?streamprofile=Media?tcp a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1; profile-level-id=420029; sprop-parameter-sets=Z0IAKeNQFAe2AtwEBAaQeJEV,aM48gA== [rtsp @ 0xa6d85e0] video codec set to: h264 [NULL @ 0xa6e07c0] RTP Packetization Mode: 1 [NULL @ 0xa6e07c0] RTP Profile IDC: 42 Profile IOP: 0 Level: 29 [NULL @ 0xa6e07c0] Extradata set to 0xa6e0c40 (size: 30)!
