Probably not (other than transiently). But there are some which
Audacity doesn't have, and which not a patent risk (e.g. Ogg Opus).
currently, anyone concerned about (for example) AAC patents has problems
getting Ogg Opus. There has also been a patent licensed MP3 encoder for
Gstreamer in the past (aimed at corporate users) and there is active
work to expose the GPU on the raspberry pi as gstreamer component
(making hardware acceleration possible).
So it's not just about absolute codec range, but also pick and choose
I think I found why it didn't work for me - I seem to have been running
the wrong binary, not the one I was compiling.
