comment:1 Changed 4 years ago by cehoyos

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

Not a regression, afaict, but important as long as FFmpeg produces invalid files without any warning.

comment:2 Changed 4 years ago by cehoyos

  • Priority changed from important to wish
  • Type changed from defect to enhancement

FFmpeg prints an error now when DVCPRO HD encoding is requested.

FFmbc is able to encode dv hd, but it's gpl
