[Linphone-developers] Jitter Buffer with Timestamp issue

[Jim Lu]

Dears,

I found some interesting in the Jitter Buffer and TimeStamp.

When I tried to make a video phone call on my Android with 

Linphone on PC. Everything seems fine here. However, if I 

tried to communicate with SIP Communicator on PC, there

will cause some delay on Android Linphone. But Sip 

Communicator seems goes fine.

So I tried to rebuild the /submodules/linphone/oRTP/src/rtpsession.c

and change the line 1067. I replaced 

mp = rtp_getq_permissive(&session->rtp.rq, ts,&rejected);

with 

mp=getq(&session->rtp.rq);

and redo the ndk-build and rebuild my eclipse project and deploy

to Android. The result seems become acceptable.

So I think maybe I can share this experience with you all.

Hoping this change will be useful for someone.

Best Regards,

Jim Lu
