Hi community, I'm currently playing Overwatch by Blizzard Entertainment. It uses Vivox sound sdk to provide Team Chat function. I captured some 300 seconds of in-game chat stream,and want to decode it. Sadly Wireshark 2.2.5(on Windows 10) can't decode this "Vivoxvani"(RTP Payload Type 126 and 127) RTP stream. Can anyone help me on this issue? Thanks.

What you'll have to do (without knowing the specifics of this codec) is to save the raw RTP payload and post process that into audio. Wireshark itself have very little codec support, besides straight up PCM A-law/u-law.

Thanks. But it seems that wireshark cannot correctly address the whole RTP stream. It is cut partially,and cannot be save fully as raw. Because Vivox RTP seems strange, the payload type changes from 127 to 126, and to some other numbers. That seems not good.
