G729 with gstreamer

Hi All,

Does Gstreamer(or any of its plugin ) supports the G729 encoder/decoder? Is yes, how is different from intel IPP library support of G729?

Regards,

Parveen Jain

There's an implementation base on the reference code. It isn't
anything distributed with GStreamer, but the elements have been tested
against a good variety of cases and works pretty well:

http://gitorious.org/gladstone

- gladstone is portable across architectures, IPP libraries work only
on Intel processors.

- gladstone has full sources available (even though you should really
ask to ITU-T in order to redistribute the reference code). IPP libs
are a "black box": if something doesn't work you'll have to beg Intel
for fixing it. The info reported here:

http://www.readytechnology.co.uk/open/ipp-codecs-g729-g723.1/

is misleading, as the codecs themselves are anyway closed source (try
to believe ;) ).

- IPP libraries are more optimised than the reference code, but there
are already a few patches in Gladstone to begin filling the gap.

- G729 BA (basically, with DTX support) for gladstone is arriving, I
just need a few sanity checks before submitting the patches (they
should get to gitorious this weekend, but no promises). Afair IPP
libraries don't have DTX support:
