Wireshark · Wireshark-dev: Re: [Wireshark-dev] Need help in Decoding RTP MultiplexstreamsinWireshark

[shruti singh <shruti.is.singh@xxxxxxxxx>]

Hi Anders

 

I have downloaded the image wireshark-win32-1.3.0-SVN-29830.exe from the path you gave. Can you please tell me what option is there for decoding multiplex stream under "decode as" option, as could not find the one

 

Regards,

Shruti

Hi,

The code is already part of trunk. You can try a development build from http://www.wireshark.org/download/automated/

The code will be included in the next major release. No planned release date yet. A development build 1.3.0

is planned to be released shortly.

 

The suport for decoding multiplex streams are very limited as I understand it. No plans exists to further develop the code.

Regards

Anders
