ffmpeg 32 bit crashed on x64 Windows for av01 format

Description

I have tried to use ffmpeg to convert av01 videos to H264 on x64 Windows, and the ffmpeg 64bit worked very well. However when I try to use ffmpeg 32bit exe to convert av01 to H264 or any other video format on Win7/Win10 x64, the ffmpeg crashed immediately and the window throws "ffmpeg has stopped working".

My command line:

ffmpeg.exe -i av01.mkv av01.mp4

If I test this with ffmpeg 32 bit and Windows 7 32 bit, it could work.
And, I can convert all other formats to H264 on Win7/Win10 x64 with ffmpeg 32 bit, except av01 format.

ffmpeg 32 bit version: ffmpeg-20181215-011c911-win32-static

So, it seems ffmpeg 32bit could only not work on 64 bit Windows for av01 format. Is it a bug or the av01 decoder's issue?

Thanks a lot for your help.

Can you post the command line you used that crashes for you and the output it printed?
Also, upload the sample somewhere if you can share it, or at least a portion of it.

av01 format

comment:2 by sunxvogy, 5 years ago

I have uploaded a AV01 format file, named d.mp4. simply rename it to d.mkv then convert it by ffmpeg 32 bit on Windows x64, you can see the error.

Following is what I got from the ffmpeg. It stopped at the converting start.

Hi I have added that into the new comment. Thanks for your help. :)

It shows "libaom-av1" as decoder

Please test if you can reproduce with ffmpeg -i d.mkv -f null -. I fear that there is not much we can do without backtrace, disassembly and registry dump as explained on https://ffmpeg.org/bugreports.html

Hi,

Yes I could reproduce the issue with this command. The window jumped out and said "ffmpeg.exe has stopped working".

My testing environment:

Intel i7-6500U, 8 GB RAM

Windows 7 x64 with latest update.

Windows 10 x64 with latest update.

Please note that only the ffmpeg 32bit throws this error on Win x64. The ffmpeg 64bit works well.

If you need anything please let me know, I will send it to you. Thanks a lot for your help.

And the ffmpeg 64bit works well, and output the info:

Replying to sunxvogy:

If you need anything please let me know, I will send it to you.

In this case, please send backtrace, disassembly and register dump as explained on https://ffmpeg.org/bugreports.html

I finally found the solution:

I changed the command from

ffmpeg.exe -i d.mkv d.mp4

ffmpeg.exe -threads 1 -i d.mkv d.mp4

Now it works!

The only logical place for a crash to be when using an external decoder and external encoder is in those external libraries, not in FFmpeg.

It seems the bug has been fixed.

I have used the version built on 2018-10-17. The latest version I downloaded works well.
