We are trying to reduce mp4 file size with ffmpeg on Win7 64bit with
critical updates done, Intel i3-2367M, using Zeranoe 32-bit precompiled
exe.
In a one minute video the image very often (90% of cases) freezes at some
point during 20 first seconds and usually restarts later. Audio continues
normally. In the example below the freezing happens in the very
beginning.
We could not reproduce the bug on another Windows PC, and on a Mac the
same command line works fine.
ffmpeg.exe -i in.mp4 -c:v libx264 -preset veryfast -crf 37 -report -c:a
copy out.mp4 -v 9 -loglevel 99
