Albert, Anotonio,
I will suggest looking at http://www.live555.com/mediaServer/ Open source C++ libraries under LGPL to support RTSP streaming. There are test programs that are available with this library that can be easily cross-compiled on Montavista Linux platform. You can use the test program to stream MPEG4 elementary stream file contents generated by DM355 encoder and can be played back using any PC client like VLC, Mplayer to playback the stream contents.

I an sure there are readymade stacks like these on the net. I have heard of live555 and others. Any ideas ?

RTP: rfc1889 RTSP: rfc2326 SDP: rfc2327 (this is useful for rtsp or multicast streams) RTCP: rfc3550 Then, depending on which standard are you working at (MPEG-4 SP, AVC) you have to verify the corresponding RFC to see how to packetizes the encoded frame.

I already worked with an H.264 Encoder & Streaming application, and with H.264 we have sps and pps periodically transmited which allows a client to receive the stream even is the sender is not at the beggining of the transmission. In MPEG-4 we only have the MPEG-4 header (I think is VOL header) at the beggining an then we just have VOP headers. The receiver cannot receive the stream if he dows not get the VOL header. My question is, how can we do this using the MPEG-4 Encoder at DM355? Does anybody knows the size of the VOL header generated by the encoder at DM355??
