Looks like libvorbis is not added part of the ubuntu mythtv packaging

appears only --enable-libvpx, --enable-libx264 are added, Thomas any chance
of getting this added?

I think I have the required libraries installed
libvorbisenc2 (1.3.5-3)
libvorbis0a (1.3.5-3)
libvorbis-dev (1.3.5-3)
libtheora0 (1.1.1+dfsg.1-8)
libtheora-dev (1.1.1+dfsg.1-8)
libvpx3 (1.5.0-2ubuntu1)
libvpx-dev (1.5.0-2ubuntu1)
libx264-148 (2:0.148.2643+git5c65704-1)
libx264-dev (2:0.148.2643+git5c65704-1)

$ mythffmpeg -y -i /storage4/recordings/4022_20171228042200.mpg -s 720x408
-g 30 -r 24 -f webm -codec:a libvorbis -codec:v libvpx -cpu-used -8
