Please provide the command line that allows to reproduce the problem together with the complete, uncut console output. Hi cehoyos,

You can find that in the document that I attached to the case. I'm pasting its content below.

#3405: Bizare behaviour with RTP mpegts sources -------------------------------------+------------------------------------- Reporter: sharbatgula | Owner: Type: defect | Status: reopened Priority: normal | Component: Version: unspecified | undetermined Keywords: RTP mpegts | Resolution: Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Changes (by sharbatgula): * status: closed => reopened * resolution: needs_more_info => Comment: Hi again, It took me a while to re-examine everything and in the meantime the ticket was closed. I'm reopening it. Although at the moment I cannot reproduce the mixing-up problem and I can't restart the server as it is in production, I nailed the problem to the handling of mpegts over RTP, which I can always reproduce now, with no involvement of external libraries and no transcoding at all, so it is purely source problem. If I do the following: ffplay rtp://@224.11.2.12:5530 or ffmpeg -i rtp://@224.11.2.12:5530 -vcodec copy -acodec copy -f mpegts some_file.ts the output is garbage and the output console is the following: ffmpeg version 2.1.git Copyright (c) 2000-2014 the FFmpeg developers built on Jan 30 2014 12:22:30 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5) configuration: --prefix=/home/vas/ffmpeg_build --extra- cflags=-I/home/vas/ffmpeg_build/include --extra- ldflags=-L/home/vas/ffmpeg_build/lib --bindir=/home/vas/bin --extra- libs=-ldl --enable-gpl --enable-libass --enable-libfdk-aac --enable- libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-nonfree --enable-x11grab --enable-libfreetype --enable-filter=drawtext libavutil 52. 63.100 / 52. 63.100 libavcodec 55. 49.100 / 55. 49.100 libavformat 55. 26.100 / 55. 26.100 libavdevice 55. 5.102 / 55. 5.102 libavfilter 4. 1.101 / 4. 1.101 libswscale 2. 5.101 / 2. 5.101 libswresample 0. 17.104 / 0. 17.104 libpostproc 52. 3.100 / 52. 3.100 RTP: dropping old packet received too late Last message repeated 1 times RTP: missed 941 packets RTP: missed 2788 packets RTP: dropping old packet received too late Last message repeated 1 times RTP: missed 3383 packets RTP: missed 3139 packets RTP: dropping old packet received too late Last message repeated 1 times RTP: missed 983 packets RTP: dropping old packet received too late Last message repeated 1 times RTP: missed 3891 packets RTP: missed 3451 packets RTP: missed 2800 packets RTP: dropping old packet received too late Last message repeated 3 times RTP: missed 1844 packets RTP: dropping old packet received too late Last message repeated 2 times RTP: missed 4736 packets RTP: PT=21: bad cseq f1d7 expected=df57 RTP: dropping old packet received too late RTP: missed 4737 packets RTP: dropping old packet received too late Last message repeated 1 times RTP: missed 1543 packets RTP: dropping old packet received too late Last message repeated 5 times RTP: missed 436 packets RTP: dropping old packet received too late Last message repeated 3 times RTP: missed -62145 packets RTP: PT=21: bad cseq 06d9 expected=f99a RTP: dropping old packet received too late Last message repeated 8 times RTP: missed -62145 packets RTP: dropping old packet received too late Last message repeated 2 times RTP: missed 14067 packets ...

I believe the problem is with the mpegts over RTP source. You could reproduce the problem if you use mpegts over RTP as a source.

In my previous post I explained the steps to reproduce it in my environment. It would be very hard to do a relevant reproduction because it's a multicast streaming from my source. I could try to setup unicast feed if you give me your public address. I published a raw recording of it on http://212.158.191.90/test.ts but when I tried to feed ffmpeg with that record, there was no problem. That proves that the problem is connected to the handling of RTP/UDP source, probably that particular source (Ericsson hw encoder). It's a null packet filled-in quasi CBR mpegts over RTP/UDP Other thing that comes to my mind is to provide tcpdump for packet analysis. I'm open for proposals, probably best thing is to try to deliver to your address. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3405#comment:7> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

If you run one instance of ffmpeg - everything is fine. If you run a second instance of ffmpeg to record another channel, the channel is recorded, which has already recorded the previous instance of ffmpeg. If set {{{-f mpegts}}}, written want channel, but the output file is corrupt. Checked for ffmpeg versions 1.2.11, 2.5.2 and N-68976-gd1c6b7v (from git) on "Scientific Linux 6.5" and ffmpeg 2.4.5 on "Fedora 21". All of the above exist in ffplay. In vlc no such effect. In http://kochkin.tk/ffmpeg/ located ffmpeg reports and recorded videos. "mplayer-stream.ts" - command {{{mplayer rtp://@238.1.1.8:1234 -dumpstream -dumpfile mplayer-stream.ts}}} "ffmpeg-one.log" and "ffmpeg-one.ts" - recording in a single copy ffmpeg. All ok. "ffmpeg-second.log" and "ffmpeg-second.ts" - the second record instances are already running at earlier instance of ffmpeg. Recorded the wrong channel, which is specified in the URL, but one that is already recording another copy. "ffmpeg-second-mpegts.log" and "ffmpeg-second-mpegts.ts" - recording the second copy with the option {{{-f mpegts}}}. Channel right, the picture is crash.
