[FFmpeg-user] crf mode in libvpx

[Boštjan Strojan]

Hi,

a. Playing around with freshly compiled ffmpeg + libvpx, but can't
seem to figure out what would be the valid "quality based" encoding
switch for libvpx? (crf/cq mode or however that is called)
b. Is internal vorbis encoder usefull? (If yes, same question - how to
enable quality based encoding?)

Basically I need a valid cli example (additional plus if it makes a
good default) :)

thanks,

b.
