Bug#627818: ffmpeg segmentation fault __memcpy_ssse3 () at ../sysdeps/x86_64/multiarch/memcpy-ssse3.S:119

[Marco Mattiolo]

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

Hi.
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
