[Live-devel] How to implement upload multiple audio streaming to rtsp server?

[Eric_Hsieh at alphanetworks.com]

Hi Ross

Thanks for your reply.

After past few days struggling, I think we found the key point.
The key point is server side always use same port to handle RTP/RTCP packet.

Transport: RTP/AVP;unicast;destination=127.0.0.1;source=127.0.0.1;client_port=46774-46775;server_port=6970-6971

Server always return server_port=6970-6971. When two client upload rtp packet at same time,
both data are received from same port, only one packet will be handled.

We change the server_port assign rule, now, anything seems to work well.
We need to do more test. Thanks for your help.

Also, it will alternate through all of the readable sockets (so that one socket cannot ‘starve out’ the others).  Therefore, if your scheduler is never handling a socket, then that means that either (1) there are no incoming packets for that socket, or (2) ‘background read handling’ was not requested for that socket.
