What you’re describing is possible; however, this is something that you would
need to program yourself; i.e., it is not available simply via a command-line
option. Note that the (custom) RTSP “REGISTER” command was originally intended
to be something that would be implemented in network cameras themselves, rather
than in the “LIVE555 Proxy Server”. However, you could, in principle, add this
functionality to the “LIVE555 Proxy Server” (or any LIVE555-based RTSP server);
see
http://lists.live555.com/pipermail/live-devel/2020-February/021495.html
However, the system that you describe seems rather complex. You’re also
omitting the HTTP server that would use the output from the “LIVE555 HLS Proxy”
(or perhaps that is part of your “[App]”??). It would be much simpler to just
to do the following (ignoring the ‘OpenVPN’s):
[IP cam RTSP]-->[Live555 HLS proxy][HTTP server]—[Home firewall]<-[App]
or
[IP cam RTSP]-->[Live555 HLS proxy]—[Home firewall]--[HTTP
server]<-[App]
I.e., Don’t implement any intermediate RTSP server at all; instead, have the
“LIVE555 HLS Proxy” read directly from the IP camera. If you do this, then
your problem becomes either:
1/ Figure out how to access the HTTP server from across your firewall (if you
run your HTTP server inside your firewall), or
2/ Figure out how to make the HLS segments+“.m3u8” file accessible across your
firewall (if you run your HTTP server outside your firewall). I.e., in this
case you could either transfer the HLS segments+“.m3u8” file across your
firewall dynamically, or somehow make the file system directory (that contains
the HLS segments+“.m3u8” file) accessible to the HTTP server outside your
firewall, e.g., using some file/directory sharing protocol (like NFS).
Either of these solutions seems simpler than messing with an intermediate RTSP
server/proxy (that implements “REGISTER”).
