File was too big for upload. afk.gif can be found here: http://i.imgur.com/7OIYI9e.gif

  • Keywords crash added

Is the issue reproducible with -vcodec mpeg4?
Is the issue reproducible with -pix_fmt yuv420p?

comment:3 Changed 5 months ago by cehoyos

Which cpu is installed on your system?

comment:4 Changed 5 months ago by cehoyos

Please also test the following command line:

$ ffmpeg -i afk.gif -x264opts asm=0 output.mp4

comment:5 Changed 5 months ago by cehoyos

  • Resolution set to needs_more_info
  • Status changed from new to closed
  • Version changed from unspecified to git-master

This may very likely be an important issue (wrong assumptions about assembler code on newer amd cpu's?) but without more information, I don't think there is anything we can do.
