 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.
