Hi , I am also running into same issue . I can record but I cannot broadcast my h264 rtsp stream from my ip camera.
here is the command which I am trying : */home/broadcaster/bin/ffmpeg -use_wallclock_as_timestamps 1 -r 25 -thread_queue_size 51200 -threads 4 -i rtsp://admin:[email protected]:8557/PSIA/Streaming/channels/2?videoCodecType=H.264 -use_wallclock_as_timestamps 1 -r 25 -b:v 2048k -bufsize 20480 -c:v copy -f avi cam.avi* *Output during recording:* ffmpeg version 2.6.2 Copyright (c) 2000-2015 the FFmpeg developers built with gcc 4.9.1 (Ubuntu 4.9.1-16ubuntu6) configuration: --prefix=/home/broadcaster/ffmpeg_2.6_building/ffmpeg_build --pkg-config-flags=--static --extra-cflags=-I/home/broadcaster/ffmpeg_2.6_building/ffmpeg_build/include --extra-ldflags=-L/home/broadcaster/ffmpeg_2.6_building/ffmpeg_build/lib --bindir=/home/broadcaster/bin --enable-gpl --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree --disable-inline-asm libavutil 54. 20.100 / 54. 20.100 libavcodec 56. 26.100 / 56. 26.100 libavformat 56. 25.101 / 56. 25.101 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 11.102 / 5. 11.102 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 3.100 / 53. 3.100 [h264 @ 0x2ba4cc0] RTP: missed 5 packets [h264 @ 0x2ba4cc0] RTP: missed 1 packets [h264 @ 0x2ba4cc0] RTP: missed 17 packets [h264 @ 0x2ba4cc0] RTP: missed 14 packets Input #0, rtsp, from 'rtsp://admin:[email protected]:8557/PSIA/Streaming/channels/2?videoCodecType=H.264': Metadata: title : RTSP/RTP stream from Network Video Server comment : 2?videoCodecType=H.264 Duration: N/A, start: 1433129457.153767, bitrate: N/A Stream #0:0: Video: h264 (High), yuvj420p(pc), 1920x1080, 25 fps, 25 tbr, 90k tbn, 50 tbc Output #0, avi, to 'cam.avi': Metadata: INAM : RTSP/RTP stream from Network Video Server ICMT : 2?videoCodecType=H.264 ISFT : Lavf56.25.101 Stream #0:0: Video: h264 (H264 / 0x34363248), yuvj420p, 1920x1080, q=2-31, 2048 kb/s, 25 fps, 25 tbr, 25 tbn, 25 tbc Stream mapping: Stream #0:0 -> #0:0 (copy) Press [q] to stop, [?] for help =========================================== If I play this file in vlc then vlc can also play. If I use libx264 to re-encode then I can put it in flv container but if I try to copy stream and put it in flv container then it does not work at all. . Even vlc cannot play such video file. Here is the command which I am using for broadcasting with ffmpeg: */home/broadcaster/bin/ffmpeg -use_wallclock_as_timestamps 1 -r 25 -thread_queue_size 51200 -threads 4 -i "rtsp://admin:admin@$1:8557/PSIA/Streaming/channels/2?videoCodecType=H.264" -use_wallclock_as_timestamps 1 -r 25 -b:v 2048k -bufsize 20480 -c:v copy -f flv rtmp://vaughn.tv.url* Please also note that I collected stream info from vlc player as it can play this rtsp stream directly from camera. here is the video codec info generated by vlc : Codec: H264 - MPEG-4 AVC (part 10) (h264) Resolution: 1920x1090 Display resolution: 1920x1080 Frame rate: 25 Decoded format: Planar 4:2:0 YUV full scale So in summary: 1) ffmpeg is detecting incoming rtsp pixel format as yuvj420p . 2) ffmpeg can record it to avi container without re-encoding it again using above command 3) but ffmpeg cannot re-stream/save it to any flv container file without re-encoding again with libx264. my question is why we are hitting this issue for yuvj420p pixel format in ffmpeg ? Is this a bug in ffmpeg ? I build latest ffmpeg 2.6.2 from source code and It works fine perfectly for my other ip camera which has yuv420p pixel format for h264 rtsp stream.
