ffmpeg exist with muxing overhead after 6-8 hours of hls transcoding from rtmp stream

[Vlad SD]

Try to run this on a latest windows build:

"C:
Dev
Tools2
ffmpeg
ffmpeg.exe" -report -i rtmp://80.232.172.37/rtplive/vlc.sdp -c:v copy -c:a copy -bsf h264_mp4toannexb -bsf:a aac_adtstoasc -hls_time 10 -hls_list_size 6 -hls_wrap 60 -start_number 1 -y "C:
Dev
Tools2
Test2
stream.m3u8"

It will run for 5-6 hours and then exists with muxing overhead message:
video:659722kB audio:130577kB subtitle:0 global headers:0kB muxing overhead -100.000003%
0 frames successfully decoded, 0 decoding errors

Is this problem only reproducible with network input or also with file (or test-filter) input?

Is network output required to reproduce the problem of does it also fail for file output?

[Vlad SD]

We observe the issue with a number of rtmp streams as an input. We do not have a file which would stream for 6-8 hours!

We tested it with HLS only. Will run with file output.

Replying to vkroutik:

You can use -f lavfi -i testsrc both to test and to produce (long) samples.

[Vlad SD]

We run the same command, but outputing to file and after 24 hours got no errors or maxing issues.

One can conclude is issue with hls parser/streamer.

Please advise if someone can fix it?

Is network input needed?

[Vlad SD]

No,

Recording failing stream to file and streaming from the file produced the same outcome => muxing overhead.

Hope it helps?

[Carl Eugen Hoyos]

If ffmpeg -f lavfi -i testsrc allows to reproduce the problem, please provide a command line using it (together with the complete, uncut console output) that allows a developer to reproduce.
If -vcodec copy is required, please provide the two necessary command lines.

[Vlad SD]

sorry, i tried to use this command

C:\Dev\Tools2\ffmpeg\ffmpeg.exe -f lavfi -i "rtmp://80.232.172.37/rtplive/vlc.sdp" -c:v copy -c:a copy -bsf h264_mp4toannexb -bsf:a aac_adtstoasc -hls_time 10 -hls_list_size 6 -hls_wrap 60 -start_number 1 -y "C:\Dev\Tools2\Test2\stream.m3u8"

but keep getting error with command line, please advise what is correct format

Does ffmpeg -f lavfi -i testsrc not work?

[Vlad SD]

Sorry, I am getting Invalid argument error, see details:

Does ffmpeg -f lavfi -i testsrc not work?

You explained above that network input is not needed to reproduce the original problem, I am trying to find a (very simply) command line that allows (both of us) to produce a testfile that allows to reproduce the problem.
If you don't want to use testsrc, maybe you have a better suggestion (that does not include recording several hours of a network stream)?

[Vlad SD]

Log file where it shows command line and error

[Vlad SD]

I have run with ffmpeg -f lavfi -i testsrc and see the same error.
I am attaching output file

video:24684kB audio:0kB subtitle:0 global headers:0kB muxing overhead -100.000087%

here is a full command

"C:
Dev
Tools2
ffmpeg
ffmpeg.exe" -re -t 1000 -report -f lavfi -i testsrc -hls_time 10 -hls_list_size 6 -hls_wrap 60 -start_number 1 -y "C:

Test2
stream.m3u8"

[Carl Eugen Hoyos]

Sorry if I missed it but could you explain again what the problem is with the command line you (just) posted? I don't see an error in the output (but I may have simply missed it).

[Vlad SD]

Sure, it exists with invalid muxing overhead of -100.000087%

see log attached

[Vlad SD]

I suggest to close this, as issue is with input which gets interupted...
