RTSP converting ASF RTP-Packets to video data

I'm working on a program processing streaming data based on MS-RTSP protocol and it's working quite well so far, getting UDP packet by RTSP.

The problem is- I cannot get through converting UDP packets to video data.

I have MS-RTSP-SPEC, RFC-2326 and MS-ASF-SPECIFICATION document,

But I have no idea what kind of data structure do 'ASF payload headers and compressed media data'

MS-RTSP DOCUMENT

Following data is one of the received packets from RTP connection,

And I have no idea which part of this MS-ASF-SPEC document has explanation of the 'ASF payload headers and compressed media data'

MS-ASF-SPECIFICATION DOCUMENT

Please help me QQ

Solution

Microsoft implemented this in their ConferenceXP package. Download the stuff here:

http://research.microsoft.com/en-us/projects/conferencexp/

Then use your favorite .NET disassembler to pull apart the RtpStream/RtpPacket stuff from the MSR.LST.Net.Rtp assembly. Or you could possibly use their classes to deal with your data.
