Hello, I agree. I was also able to create an RTP streaming application for my H264 encoder within a week. More documentation would surely be appreciated by new users. Towards this, I documented my work and put it here: (it has sample code + UML diagrams)
http://www.white.ca/patrick/tutorial.tar.gz Do you think you would be able to do the same, Luc? I'm also interested in your question about packet loss. I have not yet had time to look at that part of RTP but I will have to, very soon. Are we to assume that presentation times will be regular (like every 33 ms) and if there is a gap between them on the receiving end, we know a frame was lost? I may be wrong but that doesn't seem like an elegant solution...

Even so, Livemedia is great, to do this from scratch would have taken me several weeks. One more question though regarding packet loss. In a previous post you told me that I can detect packet loss by inspecting the presentation times at a higher level. I don't see how this can work properly? Suppose we are streaming live MPEG4 video using RTP over the internet. If a P frame isn't delivered because one or more of it's composing packets are lost, the client should stop decoding until it receives a new and complete I frame. I don't see how the client can detect the packet loss by simply looking at the presentation time. If the streaming server delivers a variable framerate then there is no way to know that a frame is lost by looking at it's presentation time or am I wrong? The only way to detect the frame loss would be if the higher level had access to the frame's beginning and ending RTP sequence numbers or am I mistaken? What would be the simplest way to detect this? best regards, Luc Roels _________________________________________________________________ Ontdek Windows Live Hotmail, het ultieme online mailprogramma! http://get.live.com/mail/overview
