Hi,

There is 100 cameras and each has own proxy process delivering streams to 
multiple different clients.

I know that processes don’t interact, but something is causing timestamps jump 
backwards when stream is flowing trough this setup. Any ideas how to debug 
presentation time calculation?

What do you mean by this?  Are you referring to multiple ‘front-end’ clients 
accessing a single proxy server (serving a single ‘back-end’ server)?  Or are 
you talking about a proxy server with multiple ‘back-end’ servers?

(I assume you don’t literally mean “multiple proxy processes running parallel” 
because, of course, if you run multiple copies of the proxy server (as separate 
processes), then they will not interact at all.  And, of course, you can’t run 
any LIVE555 code as multiple *threads* (within a single process), because the 
code is intended to be single-threaded, using an event loop for concurrency.)
