Package: ffmpeg
Version: 4:0.6.2-3
Severity: normal

I'm having a problem with ffmpeg, converting flv downloaded by youtube-dl to audio-only ogg vorbis. I had debian-multimedia repo enabled, so I purged all packages related to that repo, before generating this bugreport. Hope this really helps getting a better ffmpeg. Also hope not to waste your time.
Thank you
