ffmpeg 3.1.0 and later fails converting some MKVs with "sample_fmt" error

Reported by: julian Owned by:
Priority: important Component: avcodec
Version: git-master Keywords: dca regression
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

the error occurs at least on the file 'Goodnight.Mommy.2014.Bluray.1080p.DTS-HD.x264-Grym.mkv' but this one is 13GB and hard to get.

i tried to cut out a smaller sample out of the MKV so i could upload it here, but unfortunately the error doesn't occur on the cut sample. if anyone has any ideas for getting a smaller sample to exhibit the same issue, please let me know.

so, assuming you have downloaded the 'offending' file and named it bug.mkv
{{
ffmpeg -i bug.mkv -acodec ac3 -vcodec copy bug.mp4
}}
works fine for every version up to and including version 3.0.2
versions starting with 3.1.0 and including up to git snapshot 82713-g4e6d1c1 from 1.12 just fail to convert the file with:
'Error setting option sample_fmt to value'

i'll upload complete command line outputs for conversion with working (3.0.2) version and failing version (3.1.0).

if there are any additional informations i could provide please let me know.

well, i've just cut the first 80MB of the offending file to create a sample to reproduce the issue. its not ideal but it works. if you have a better idea let me know.

please download
https://dl.dropboxusercontent.com/u/7221986/bug.mkv

if you try to convert it with the above command line with v3.0.2 it works fine until it hits the premature end of the file

if you try to convert it with 3.1.0 or later the mentioned error occurs

Is this issue reproducible with current FFmpeg git head?
Please post ffmpeg -i output for the 80MB sample, please do not attach compressed console output.

Is this issue reproducible with current FFmpeg git head?

as i mentioned i reproduced it using the precompiled git head from 1. dezember. i now reproduced it using precompiled git head from today ( ffmpeg-82780-gb6f80b1 ) too.

comment:4 Changed 8 months ago by cehoyos

So why did you upload console output for old versions of FFmpeg?
Please post ffmpeg -i output for the 80MB sample.

Please post ffmpeg -i output for the 80MB sample, please do not attach compressed console output.

So why did you upload console output for old versions of FFmpeg?

3.1.0 is the first release with the bug and the console output with 3.1.0 and any other later version is completely identical

comment:7 Changed 8 months ago by cehoyos

  • Component changed from undetermined to avcodec
  • Keywords dca regression added
  • Reproduced by developer set
  • Status changed from new to open

comment:8 in reply to: ↑ 6 Changed 8 months ago by cehoyos

Replying to julian:

the console output with 3.1.0 and any other later version is completely identical

For future tickets: Please remember that this is completely irrelevant, support for releases is limited, releases get no support on osx and on this bug tracker, you are required to test current FFmpeg git head when reporting issues.

comment:9 Changed 8 months ago by heleppkes

The file doesn't have any audio for several seconds, the console output does tell you what to do to fix it - increase analyzeduration.

comment:10 Changed 8 months ago by cehoyos

If you believe that the text on https://evermeet.cx/ffmpeg/ is unclear please help Helmut and me to improve it.

comment:11 Changed 8 months ago by julian

i can confirm that just reverting commit 39f7620d76c7a133535ed7a535f7a74fefa6e435 makes the bug go away

I can reproduce the bug and uploaded it to https://i10z.com/tmp/bug.mkv , @cehoyos please upload it to the ffmpeg samples directory so I can delete it.
