Subject: Implementing RTP streaming from live source /multithreading issues/


I have following problem. I have to implement RTP server, which streams the 
data from video capture board and on the other side I have to implement RTP 
client which receives and decodes that stream. The problem is how to notify 
server thread that a new video frame is available for streaming ? My capture 
board delivers frames in separate threads ( I have the same problem on the 
client side. LiveMedia runs in separate thread but I need to connect, 
disconnect and invoke PLAY,PAUSE from main GUI thread ) I searched through 
list archives but found only some ugly-hacks with setting bool variable and 
checking it when select timeouts. I need more efficient solution, because 
I'm going to stream up to 400fps from twenty or more cameras ( it can be 
also a one camera at 1fps ). Is there any other solution eg. dummy socket or 
changing all sockets to WSAEventSelect() ( I'm running it on Windows ) ? 
Anybody tried it ?
Please help ...

Thank you in advance
