FW: [Icecast] Multi-Level Fallbacks

[Klaas Jan Wierenga]

Do you mean you can relay within a single icecast server instance? So the
relay is running on the same icecast process from which it is relaying a
stream?

samplerate and channels are the main ones to keep the same, not all
systems can handle those changing mid stream.

The easiest way to separate clients based on originating mountpoints is
to use local relays

/b relays /a
/c relays /a

/d fallback to /b
/e fallback to /c
