<br>
You’re still not explaining your problem very well, but I assume - from your description - that you want something like this:<br>
<br>
<br>
back-end RTSP stream 1 -> +————————————+<br>
back-end RTSP stream 2 -> | |<br>
back-end RTSP stream 3 -> | Your ‘reverse’ proxy server | -> front-end RTSP client<br>
… | |<br>
back-end RTSP stream N -> +————————————+<br>
<br>
<br>
If this is the case, then I’d describe your "‘reverse’ proxy server” as being in front of "multiple backend video sources”; not “behind multiple backend video sources”.<br>
<br>
Is your "‘reverse’ proxy server” intended to (somehow) select from one of these N back-end RTSP streams - so that only one back-end RTSP stream is streaming at a time (rather than having all back-end streams flowing simultaneously, with your ‘server’ somehow ‘mixing’ the incoming streams)? If so, then how do you intend your server to choose which back-end RTSP stream to use? In other words, what criteria would your server use to decide which back-end RTSP stream to use?<br>
<br>
The usual way to do this would be to just use the stream name (in the front-end “rtsp://“ URL) to select the back-end stream. I.e., each of the N back-end RTSP streams would be represented by a different stream name requested by the front-end RTSP client. If these N back-end streams are known in advance, then you could do this already, with our existing ‘LIVE555 proxy server”, by running:<br>
live555ProxyServer <back-end-RTSP-stream-URL-1> <back-end-RTSP-stream-URL-2> … <back-end-RTSP-stream-URL-N><br>
