IIRC Ubuntu has full support. Also openSUSE has Packman where you could get 
full libavcodec builds.

But overall, gstreamer is probably the better interface to look at here, as it 
actually provides a plugin architecture that people can plug their almost-legal 
codecs into.

The main reason I brought this up was because I'd like to know whether there's 
a particular benefit in using vaapi directly vs using gstreamer to encode this 
:).
