Alternate Codec Support

[GoogleCodeExporter]

If possible, it would be REALLY helpful if multiple codec support was
included as there are a couple codecs that would be much better for a phone
like this. Or even set a fallback codec, however that is not even close to
mattering...

The codecs that would be EPIC to see supported are:

ILBC - Internet Low Bitrate Codec (Good for edge, or low signal)
GSM  
G729
G711

Thanks!

g729 codec in sipdroid.you only need G729.java wrapper.i gave it to all in 
previous.you just add "libs" folder into your project directory.

Hi,

I am novice here.

I have added the library to my lib directory in Samsung Galaxy and changed the 
rights, owner and group as other codecs:

# pwd
/data/data/org.sipdroid.sipua/lib
# ls -l
-rwxr-xr-x system   system      92503 2010-10-03 18:59 libbv16_jni.so
-rwxr-xr-x system   system      27903 2010-10-03 18:59 libg722_jni.so
-rwxr-xr-x system   system      75472 2010-10-03 19:00 libgsm_jni.so
-rwxr-xr-x system   system      50938 2010-10-03 18:56 libOSNetworkSystem.so
-rwxr-xr-x system   system      94100 2010-10-03 18:57 libspeex_jni.so
-rwxr-xr-x system   system      83715 2010-10-16 16:47 libg729_jni.so

However, I still don't see G729 codec in the list of my codecs in Sipdroid. 
What else need to be changed? What I suppose to do with G729.java wrapper?

we are running a Brekeke SIP Server and SIPDROID on many phones which works 
very well, especially with residential and commercial VOIP/SIP gateways. 
However we cannot get SIPDROID Audio working on the Freescale IMX51 chipset, as 
Freescale supports only  g.722/723/726/729. Any advise Kind Rgeards

please you follow my previous mail how to add g729 codec.you need to add 
G729.java wrapper and some change needed in Codecs.java,UserAgentProfile.java 
and UserAgent.java file

Original comment by ocean.ra...@gmail.com on 11 Oct 2011 at 8:47

[GoogleCodeExporter]

ocean.ra: It seems the developers entirely forgot about us and never integrated 
it into official Sipdroid?

Meanwhile I have a new phone which should be better compatible with it.

However, your instructions are spread all over this issue report - could you 
please make ONE post, with all the required modified files, and instructions to 
follow?

Thank you!
