Description
I have a problem with FFmpeg being stuck fixing non-monotonous DTS of a very long stream. I think that it's a bug in FFmpeg because it keeps on changing the DTS to the previous value. Hopefully somebody has a clue what's going on here.
My setup is as follows:
A program combines segmented TS files of two short clips – each chunk with a duration of 1 second – encoded with identical settings at 24 fps. The program mixes the files so that the sources are alternated every few seconds, copies the files into a folder with consecutive names and creates an index file to feed the concat demnuxer. From that input a RTMP stream is produced.
Excerpt from concat.index:
ffconcat version 1.0 file 'output/00000000.ts' duration 1.0 file 'output/00000001.ts' duration 1.0 ... file 'output/00099998.ts' duration 1.0 file 'output/00099999.ts' duration 1.0 file concat.index.alt
At the end of the index file another index (concat.index.alt) is referenced that also refers to 100,000 chunks and the previous index concat.index. This should produce an endless loop.
Since timestamps of the input files are non-monotonous, FFmpeg has to do a lot of fixing. This is expected. But after 26.5 hours of streaming the process got stuck for the first time.
At this time the following error occurred:
[concat @ 0x40dd420] Invalid timestamps stream=0, pts=-5405567, dts=8584510275, size=37014
I kept the process running for almost 45 hours. FFmpeg reported a time of about 37 hours in the end, so it was stuck for 8 hours in total. I killed the process after it consumed 30 Gigabytes of RAM.
Fps increased from 24 to 158.
Since the log file is very large (12 Gigabytes) I am going to post excerpts only. I added comments about my observations.
Please note: The line numbers I refer to are the numbers VIM reported. Here I inserted newlines to have a more readable output.

Omitted 2236 lines (27 => 2263).
A warning about non-monotonous DTS now and then but nothing serious.
Then, after 26:29:43.23 of streaming this message occurs for the first time:
[concat @ 0x40dd420] Invalid timestamps stream=0, pts=-5405567, dts=8584510275, size=37014
At that time 2,288,870 frames have been encoded which translates to about 26:29:29 at 24 fps.

The stream reports a runtime of about 10 hours in that window.
FFmpeg increased the frame count by 19,090,653 (4689206 => 23779859) during that time. At 24 fps that would be almost 221 hours. But fps is now at 152!

I record video streams from 3 cameras.
Stream 1:
Input #0, rtp, from 'rtp://225.1.1.1:1024':
Duration: N/A, start: 60424.501000, bitrate: N/A
Program 1
Stream #0:0: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(progressiv
e), 1920x1080 [SAR 1:1 DAR 16:9], 50 fps, 50 tbr, 90k tbn, 100 tbc
Stream #0:1(eng): Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, mono,
fltp, 164 kb/s
Streams 2,3:
Input #0, rtsp, from 'rtsp://192.168.3.36:554/stream1':
Metadata:
title : Session streamed by "Pelco Streaming Server"
comment : stream1
Duration: N/A, start: 0.219167, bitrate: N/A
Stream #0:0: Video: h264 (Baseline), yuv420p(progressive), 640x480, 25 fps,
25 tbr, 90k tbn, 50 tbc
I record each of them with segmentation every 1 minute using separated ffmpeg instances like:
ffmpeg -i "rtsp://192.168.3.36:554/stream1" -vcodec copy -an -f segment -strftime 1 -segment_time 60 "novus-%Y-%m-%d_%H-%M-%S.ts"
Every 13 hours 14 minutes (from beginning of recording) each ffmpeg stops recording with messages like "Non-monotonous DTS in output stream 0:0". And it doesn't matter when I started every ffmpeg intance: if I started instance №2 1 minute later that instance №1, it will stop recording in 1 minute after №1 accordingly. I tried it on two PC: Windows Server 2012 x64 and Windows 10 x64.

I can't record video infinitely. Every 13 hours I have broken recording. I tried to record with "-copytb 1" but it doesn't help.
Does anyone know how to solve it? I can provide you with another information you need about this.
Update: If I wait 13 hours after bug appeared, the recording starts again.

Replying to Gnitry:
I have the same problem
This seems very unlikely: The original issue is about concatenation of mpeg-ts files, you are apparently describing a network issue. Please post your question on the user mailing list or open a new ticket. If you open a new ticket, please remember not to use external resources (except for large input files), post all information in the ticket.

I choosed this ticket because it has problem with negative DTS, like I have.
Yes, log file is big.
Ok, I will write a new ticket.
Note:
See TracTickets
for help on using tickets.
I tried 3 more configurations and the process always died after 26.5 hours as before. My latest command is:
I am sure now that FFmpeg has some kind of hard limit, maybe because the PTS is so far off. I can't explain why the PTS has such a huge negative value, though.
