Problem using G722 with PJSIP 0.8.0 over WM6 platform

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I am trying to use G722 codec implementation with PJSIP 0.8.0 version on a Windows Mobile 6 platform. The clock rate has been set to 16000 Hz while initializing pjsua.

When I establish a call from an actual Windows Mobile device to WM6 Emulator running on WinXP machine, I am observing media flow only in one direction. The first few RTP packets flow in both directions after SDP negotiation but the RTP flow from Emulator to Device stops thereafter. Media flow is perfectly fine from Device to Emulator and I can clearly hear the voice on Emulator machine. However, Emulator does send RTCP report packets to Device on regular basis; every 5 seconds I guess.

I am not able to ascertain whether this is an issue related to limited CPU processing power of WM6 platform or some media related issue of using G722 with PJSIP 0.8.0. Can anyone suggest what can be the root cause of this problem?

I am attaching the generated log files for both sides.

Regards
Girish
