restructuring amr plugins

[Stefan Sauer]

hi,

we have gst-plugins-ugly/ext/amrnb and gst-plugins-bad/ext/amrwb. One
issue is they are both GPL, but infact the amr{nb,wb}parse elements in
there don't use the GPL lib at all.

I'd like to see
1) amrwb to be move to -ugly
2) amr{nb,wb}parse moved to -good as armparse as LGPL
3) Nokia would like to contribute rewrite of the parsers using slomos
GstBaseParse. This can clearly happen as an improvement later on.

How could we time that with all the plugin moving windows?

Stefan

　　Some other questions by the way:
　　Are there any other voice codec in gst world? For example: G729, G.711, GIPS:iBLC, G.723.1 etc?

YOu should see gstreamer more as the framework. Codecs usualy come with legal
implications. ffmpeg has a lot, but that would not help business use cases.
Whenever a codec is royalty free and openly documented it could be added.

G.711 is supported already (plugins are called alawenc/alawdec and
mulawenc/mulawdec). I don't know of any free (as in copyrights, not
patents) implementation of the others. If there are, its probably pretty
easy to make a gstreamer element. Also, there exist non-free
implementations. For example, the Nokia internet tablets have G729 and
iLBC (but using proprietary dsp-based encoders/decoders).
