Bizare behaviour with RTP mpegts sources

[sharbatgula]

Summary of the bug:
Hi,
I'm transcoding a bunch of SD sources from SPTS mpegts transported on different multicast addresses with RTP on port 5530. (VBR h264 video, mp2 audio)
When I transcode the first source from mcast IP1:5530 the output is sort of OK (occasional green patches and false reporting of unsupported source features)
Once I run a second ffmpeg instance to transcode source IP2:5530 the second instance is not ingesting IP2 content but IP1 and both instances start to interfere and they don't even come to a state to start transcoding.
It's bizare that even two ffplay instances tuned to different sources play back the same content!
I tried playing back with vlc and there is no such problem.

% ffmpeg -y -f mpegts -i rtp://@239.2.2.22:5530 -threads 0 -acodec libfdk_aac -ab 64k -ar 44100 -vcodec libx264 -vprofile baseline -vlevel 1.3 -x264opts fps=25:keyint=100:bitrate=200 -s 320x240 -f mpegts udp://224.10.2.3:5004?pkt_size=1316

I uploaded a sample of my mpegts on: ftp://upload.ffmpeg.org/MPlayer/incoming/ts__sample.ts

ffmpeg version 2.1.git
built on Jan 30 2014 12:22:30 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5)

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

Hi cehoyos,

You can find that in the document that I attached to the case. I'm pasting its content below.
Please note that sometimes it is enough to just ffplay rtp://@multicast_ip:port and get

ffmpeg -y -f mpegts -i rtp://@239.2.2.22:5530 -threads 0 -acodec libfdk_aac -ab 64k -ar 44100 -vcodec libx264 -vprofile baseline -vlevel 1.3 -x264opts fps=25:keyint=100:bitrate=200 -s 320x240 -f mpegts udp://224.10.2.3:5004?pkt_size=1316

Please reopen this ticket if you can provide complete, uncut console output of a failing command.

If the problem is reproducible without external libraries (libx264 and libfdk_aac), please don't use them as external libraries make reproducing the issue more difficult.
Is network output needed to reproduce the problem? If not, please use file output.

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:

My guess ffmpeg is detecting the source as RTP AV profile straming, not mpegts over RTP.
By specifying the input type more precisely, i.e.

ffmpeg -f mpegts -i rtp://@239.2.2.12:5530 -vcodec copy -acodec copy -f mpegts some_out.ts or
ffplay -f mpegts rtp://@239.2.2.12:5530

the picture and output file is stabilized but very often I have sporadical green patches with the following frequent console errors:

Now, to nail the problem further, I decided to remove the RTP headers from the source by using eithr multicat or remuxing with VLC

multicat -U @239.2.2.12:5530 224.11.2.12:1234

When I finally invoke ffmpeg with the following:

ffmpeg -i udp://@224.11.2.12:1234 -vcodec copy -acodec copy -f mpegts test.ts

everything is fine.

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.

BR,
Sharbat

[Carl Eugen Hoyos]

How can I reproduce the problem?
Is there a public IP address that I could use here?

[sharbatgula]

How to reproduce?

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.

[thovo]

If you use "-f mpegts -i rtp://...", the mpegts demuxer is used and the stream is processed as it would be plain mpegts data.

[Oleg K.]

This problem is also with me.

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.

Sorry my English...
