i thanks a lot everybody Now- how do i encapsulate a h264 stream + audio stream (very simple format - maybe even non compressed) + auxiliary data in such a file? Another question: if I want to stream rtsp - how do I do it ? I need the full souirce code of those solutions - and possibly code that works also under windows ce Thanks again Albert
