Wireshark · Wireshark-dev: [Wireshark-dev] listen_rtp plugin

[Alejandro Vaquero <alejandrovaquero@xxxxxxxxx>]

Hi All,
   Here is the "listen_rtp" plugin that allows to listen audio RTP 
conversations.

   The plugin is integrated to the "Voip Calls" feature. There is a new 
"listen" button in the "Voip Calls" that once the calls are selected and 
the "listen" is clicked, a new window will open. In this window you can 
change the simulated jitter buffer to be used for decoding the RTP 
packets. In this first implementation, only a static jitter buffer can 
be simulated. Then pressing "decode" will decode all the RTP and 
generate the graphical view of the audio channels. From there you can 
select up to two channels at the same time (to be played in the left and 
right channels) and then play, pause, stop,etc.....ok, the attached 
screenshot it is self explanatory (hopefully).
   The only codecs available from now are G711u and G711a law.

   The PortAudio (www.portaudio.com) library is used to play audio. 
This is an open source cross-platform Audio library. I have tested this 
on Windows XP  and in a linux FC4.

   I modified the Makefile.nmake and Makfile.am files, acinclude.m4, 
config.nmake and configure.in to be compiled in Windows VC6 and Linux 
(thanks Luis for the lua staff as I was totally lost here). Not sure 
what else it is needed for other platforms.
   For windows, the user can comment the PORTAUDIO_DIR parameter in the 
config.nmake file to avoid the plugin to be compiled.
   For linux, by default the plugin is not compiled unless the user 
uses the "--with-portaudio" argument when running "configure". To be 
compiled in linux, the "portaudio" package needs to be installed.

   The attached files contain:
listen_rtp.patch: this is a patch that has the changes for the "Voip 
Calls" files, and all the Makefiles and auto staff.
listen_rtp.zip: the plugin files to be added to the plugin directory
portaudio_v18_1.zip: this file is the PortAudio Window library that need 
to be downloaded when using "nmake -f Makefile setup".
listen_rtp_screenshot.png: A screen shot of the plugin.

TODO:
  - Tests in other platforms.
   - Make the changes in the Windows installer, to have the option to 
install it or not (same as the Lua plugin). I don't know where to start 
looking for this.

   Any comment or enhancement are very welcome.

Regards
Alejandro
