  avcodec/x86/mpegvideoenc : remove av_assert2() for variable alignment
  It's safe to assume that LOCAL_ALIGNED_16 does indeed align. Otherwise
  
  we would have many more problems...
  This assert was added in f8188626 all the way back in 2003.

• ffmpeg encode video produce incorrect mediainfo encoding settings

  25 août 2021, par Foong

  I've been trying to do batch encode videos to H265 format. I am using media-autobuild_suite to build ffmpeg and have already updating ffmpeg to the latest version.

  However, the Writing library and Encoding settings output is incorrect. Before update ffmpeg doesn't have this issue. I wonder what have been missing that causing this issue.

  I have tried with simplest ffmpeg from official wedsite and encoding cli but the output still same.

  


  ffmpeg -i "input.mkv" -c:v libx265 "output.mkv"


  


  Update :
Tried converting video with FFmpeg 4.4 "Rao" from https://www.ffmpeg.org/ working fine. But compiled ffmpeg from media-autobuild_suite, tried with light build and full build, Writing library and Encoding settings output still incorrect.
