Pre-loaded tuner option

[Dan_Austin 62]

Based on a comment in the live TV forum, it struck me as a way to
greatly speed up common live TV channel tuning.

The idea is to allow the server admin to set a number of tuners, be they
IPTV or HDHR, that can be used to tune to to channels that are not
actively being watched.  The channels would be selected based on
their 'favorite' score.

When no one is watching, the stream goes to the NULL device, or
equivalent.  Once a user selects it, there is an active stream already
remuxed or transcoded, greatly reducing the time to get the channel
loaded.

For recordings or a user wanting to watch a channel not pre-tuned,
the system should check to see if anyone is watching an tuner and
hijack the least favorite, or any tuner not in the pretune pool.

Instead of automatically using all tuners, I'd suggest a configurable
number.  Especially to keep an IPTV newbie from setting up hundreds
of pretune streams and then wondering why they blow through their
ISPs data limits, with obvious warnings about cummelative bandwidth
usage.

I think a lot of the elements already exist in Emby, favorite (score based?)
and tuner sharing.  I won't claim the rest should be easy, but would be
a big user experience win.

Double bonus points if this also includes a limited buffer on each pretune
stream so it would be possible to rewind to the start if you tune to a channel
a little bit late(which would likely break tuner sharing, but might allow getting
a full recording).

Hi, yes it's not a bad idea for the future. Thanks for the feedback.

Going to need a bigger transcoding SSD!
