What RFC's are you referring to in the text below ?

Presently wecandecode only Non -Multiplexed RTP streams in wireshark. A multiplexed voice packet is composed by concatenating RTPencapsulatedvoice packets and IP and UDP headers. Below is the Multiplex Packet format IP UDP Multiplex Header Compressed RTP Header RTP Payload Multiplex Header Compressed RTP Header RTP Payload This Multiplex header is repeated in beginning of each RTP packet. SoI was thinking of way to extract this multiplex header & use it to decodeeachRTP packet following this Multiplex header. I supose we need to make a dissector packet-rtpmultiplex.c regestringtoa UDP port as a starting point. Dissect the multiplex header, decompress the rtp header and have theRTPdissector dissecting the resulting "RTP packet" - decompressed header+data. Could you help me in dissecting the multiplex header and make thiswork.Also I need to know the steps to write our own filters in wireshark It would be great help.
