RFC2733 "An RTP Payload Format for Generic Forward Error Correction" requires the RTP header extension (X) bit to be used in an otherwise non-standard way. The header extension is never present, independent of the value of the X bit. The X bit contains the result of the FEC protection operation as applied to each of the data packets protected by that FEC packet.
I am considering adding support for this into Wireshark. Has any thought ever been given to incorporating RFC2733 support into the RTP dissector? Are there any good reasons why this should not be supported? Further, I would be interested to hear suggestions on how I might implement this. The dissector working on the RTP payload would be responsible for the majority of the RFC2733 dissection, but the RTP dissector itself would need to be aware of its payload type in order to treat the X bit correctly. Thanks for any comments. Mark _______________________________________________ Wireshark-dev mailing list Wireshark-dev@wireshark.org http://www.wireshark.org/mailman/listinfo/wireshark-dev
