comment:1 Changed 5 years ago by cehoyos

  • Component changed from undetermined to avcodec
  • Keywords snow added
  • Reproduced by developer set
  • Status changed from new to open
  • Version changed from unspecified to git-master

Probably not really a regression, but decoding output looked much better before bb29ee62
