[asterisk-biz] Re: [asterisk-users] H.264 *Not Patented*

[Michael Jerris]

1.	The case in question about H.264 seems to indicate that maybe 1
pattent on H.264 is invalid, there are many.
2.	H.264 is a video codec, not an audio codec, so I suppose you
could encode audio on it if you wanted to plot the audio signal on a
graph and encode that, but not sure how useful that would be
(shamelessly stolen from a certain spandsp author).

 

If your really looking for a good codec that isn't encumbered by patents
similar to g729, look at speex.  It is the best alternative with similar
characteristics.
