Wireshark-users: Re: [Wireshark-users] Playing RTP on Mac OS X?

My apologies, the exact wording of the error message is "Unsupported codec".

The capture I'm using is the example provided at http:// action=AttachFile&do=get&target=rtp_example.raw.gz

I just poked a little more at it and it appears only one of the streams messes up:
If I choose
Statistics -> RTP -> Stream analysis
and then export both channels to .au, it works just fine. (and the file can be played just fine.)

Statistics -> RTP -> Show all streams -> analyze
an then exporting, repeatedly tells me "Can't save reversed direction: Unsupported Codec", no matter which stream I select as "forward"
(this was the route I usually went )

The codec reads "ITU-T G.711 PCMA".

"codec not supported" seems to me an error coming from portaudio, as
there's no similar wording in the code. You can see the graph so its
g711a or g711u that I guess they should be support.

Which codec the stream is using?

Can you share the capture so me or another developper can check this out?
