I'm attaching my version of mediastreamer2/plugins/msg722.c
There is two IMPORTANT things to remmeber about g722
1) when building ding SDP the fmt should be G722/8000
2) The actual sampling rate should be 16000HZ but the RTP timestamp
should be based 8000HZ
Thanks

Yeah, that's right!
Is there anybody who has allready made a G722 plugin (the sama as msilbc
plugin) for Linphone (so that i can compile that first and give some
parameters to the linphone configuration to use them)?
I'm actually in the middle of writing a Linphone plugin, but this is for other reasons. For a start,
I took the msx264 plugin code and replaced it by my own code preserving the needed structure. But I
better had had a kind of template or decent guide to do that.
Perhaps we can ask Simon Morlat how his approach to writing a plugin is?? Simon, do you have some
kind of plugin template?
-Simon.
Well, as I said, I never got the codec actually running.
You seem to have done the same steps as I did in order to integrate that
particular piece of code
from the internet. So I'm not further than you.
But the thing with doing it as a plugin seems very clever to me! I like
the idea of a plugin being
generally independent from the main program.
Before saying any more I'll also have to have a look at some already
existent plugins in order to
understand how they work.

Hi!
Nice to hear!
Can you explain the steps that you do to get this G722 working (to get
this in the codec section)? I'll try that first on a normal i386/i686 PC
and after that i will try to recompile it to an ARM device.
Hi!
Yeah, that was exactly was I was trying to do 2 months ago
(coincidentally
also on an ARM device). I
also got everything to compile and if I remember it correctly I even
got
G.722 to be standing in the
audio codec list.
But I unfortunately never got the codec really running which I don't
understand...
I would also definitely be interested in having G.722 integrated in
Linphone - even if it would be
with the help of a preprocessor switch or something. (Like
USE_G722_CODEC)

Hello,
I want to use the G.722 codec on a 1.2Ghz ARM Device in the future.
For
now i want to use linphone incombination with the Wideband G.722
codec.
I follow the following steps:
1. I download all the G722 files @
http://lists.gnu.org/archive/html/linphone-developers/2009-09/msg00034.html
2. I unpack the files and put msg722.c, g722_encode.c and
g722_decode.c
into mediastreamer2/src
3. I put the g722.h file into the
mediastreamer2/include/mediastreamer2
directory
4. I added two new filter id's to allfilters.h
5. I add all the C-files to the mediastreamer2/src/Makefile.am
6. I add
"linphone_core_assign_payload_type(&payload_type_g7221,9,NULL);"
Compiling works ok with the current version linphone-3.3.1.tar.gz. But
after compiling , and starting program i get no other codecs than the
g711A/U,GSM and not the G722 one.
Can anybody help me to get this G722 wideband codec working (or add
this
to the current linphone)?
