[mythtv] How to integrate streaming content

Fri Jan 9 12:25:34 EST 2004

Not sure how this would be coded, and I'm still in the process of 
completing my myth setup, so some of this may or may not make 100% sense :)

However, the ideal way I'd like to see streaming stuff like Internet 
Radio, webcasts, etc work would be to add them as channels on the mythtv 
guide (not sure how you'd put the schedule in, since obviously xmltv 
won't get these...), so that I could just select them and record them 
alongside other programs.  I suggested something like this a day or 2 
ago by way of a software tuner (in place of a hardware tuner like a 
bttv, etc card), so that you could define a tuner, set a schedule 
against it, and record stuff on it without a new mythmodule.

I have no idea how much work this would be, but that would - at least to 
me - be the easiest way to _use_ it...  Don't know if you'd have to have 
a "tuner" per type (i.e. one for real audio, etc) or one tuner with 
plugins for different formats, etc, and may have to translate to a 
format Myth understands (i.e. mpeg2, etc).  Does this even sound at all 
reasonable?
