HTTP Live Streaming using Apple mediastreamsegmenter

I would like to implement HTTP live streaming for iPhone/iPad. I am following the apple standards and tools for same.

As of now my video source is one giving me live video from rtsp://123.123.123.123:554/mpeg4 (sample IP). but as HTTP live streaming and mediastreamsegmenter required to pass source over UDP network so i have twisted way bit.

So that i have used VLC player and first stream RTSP to UDP.

For example, i have stream video source from rtsp://123.123.123.554/mpeg4 and redirected it to udp://@123.123.123.17:1234 (sample ip). i have tested this with two instance of VLC on same machine to check whether live streaming is played or not. it is working fine on VLC.

now I am user MAC OS 10.6.x (Snow leopard). and use latest tools (downloaded from Apple) fro HTTP Live Streaming

I am executing the following command from terminal

mediastreamsegmenter -b http://demo.dummy.com/stream -s 3 -D -f /Desktop/StreamParts 123.123.123.17:1234

here http://demo.dummy.com/stream - server /Desktop/StreamParts - Local Folder for saving .ts files 123.123.123.17:1234 - UDP url (from where live streaming is done)

But the problem is when i execute this command. it is giving me error like

no start access unit error in pid 44(video) -- cc value should be 9 is 10, 1 is 2, 5 is 6, etc.

any idea? what is going wrong here? and what this error message is showing?

My hunch would be that the transport is incompatible. Apple's tools (i.e. mediastreamsegmenter) are expecting an MPEG2 transport stream over UDP, not just RTSP sent over UDP. The problem I have, which I'm afraid will be your next question, is how to correctly generate a MPEG2 transport stream.
