[mythtv] "New" Feature: RTSP streaming for myth backend

[Stormboy]

Why not implement a controllable RTP transmitter for MythTV content that
transcodes the content and sends it via RTP?

You could then use existing application/codebase for the RTSP server
(live.com/DSS/etc.), reflecting the RTP stream.  The integration with an
RTSP server might involve dynamically creating or starting an RTP
transmitter upon URL request of the RTSP server.

Alternatively, if you are streaming on a local network (or larger
network if allowed by routers/firewalls), clients could connect directly
to the RTP stream.  You just need to deliver an SDP spec to the clients
so they can tune into the stream(s).

I think there is RTP code in gstreamer and live.com that may be used
(not sure of live.com's licensing though).
