Question

After updating youtube-dl, I typed the following command to extract some audio:
youtube-dl -x --audio-format mp3 https://www.youtube.com/watch?v=drkhv11ljEs

and received the following error message:
ERROR: WARNING: unable to obtain file audio codec with ffprobe

Based off another forum that seemed to have a related issue, I typed:
ffprobe -show_streams 'file:'01- '\''Tris'\'' (ft. Ellie Goulding) Divergent - Original Motion Picture Score-drkhv11ljEs.webm'

and received this error:
ffprobe: error while loading shared libraries: libxvidcore.so.4: cannot open shared object file: No such file or directory

I haven't been able to find anything in other forums (or in this one) that address this issue. It seems to be an error with ffprobe, not youtube-dl, but I figured here was probably as good a place as any to see if anyone else has experienced the issue. Thanks in advance.

Sincerely,
I Have No Idea What I'm Doing
