Wireshark · Ethereal-dev: [Ethereal-dev] Dissector plug-in for Pro-MPEG CoP 3 r2 (2dparityfec)

["Mark Lewis" <mlewis@xxxxxxxxxx>]

Hello,

 

I have developed a dissector plug-in for Pro-MPEG Code of Practice #3 release 2 FEC data (http://www.pro-mpeg.org/publications/pdf/Vid-on-IP-CoP3-r2.pdf). This protocol is for sending FEC data over RTP.

 

The protocol defines that this data is always sent with RTP payload type 96 (0x60). My plug-in currently recognizes all RTP traffic with payload type 96 as belonging to this protocol. However, payload type 96 is specified by RTP as dynamic and may be used for other purposes within other protocols. I don't want to issue my plug-in and then find that data of type 96 that is not Pro-MPEG FEC is then dissected as such.

 

Please could somebody suggest the a mechanism for dealing with this problem?

 

Thanks,

 

Mark
