Re: G726 RTP payload packetizer

Hi all,

To add one more point, is this implementation covers the recommendations of
RFC 3551.?

Thanks,
Kumar KM

Hi all,

I have been using the G726 RTP packetizer for streaming from Gstreamer to
VLC player. when I use a Little -endian(LE) input data, for 32kbps & 16kbps
it works fine, without any noise. But for 24kbps & 40 kbps it gives noise
for LE data. When I use all test streams with BE, then it works fine. Does
this G726 RTP packetizer accept data in Big-endian(BE)? Can somebody give
more info on this.

Thanks in advance!

Regards,
Kumar KM

Re: G726 RTP payload packetizer

Our audio guy here (who wrote the G.726 payloader) has looked
at it and it seems correct that it does not follow RFC 3551
correctly for 24/40 kbps. This is due to historical reasons. :(
Could you add an entry to the bugzilla database for this, and
he will take care of it?
