  • Component changed from ffmpeg to undetermined
  • Priority changed from important to normal

Please test current FFmpeg git head and please provide the command line that allows to reproduce your issue together with the complete, uncut console output to make this a valid ticket. Do not use -loglevel warning when reporting issues here.
