[mythtv-users] How to choose between 2 backends ?

[Barry Martin]

Hi Klaus!

Some interesting inquiries you have been making!
> I have frontend and backend on a desktop pc.
>
> But I would also like to record tv on a laptop. This laptop has no screen and
> the graphic card is probably to small to watch tv. I installed frontend on it
> to test it, but now I want to use only the frontend on the desktop pc.
>
> So sometimes, I want to record tv on the laptop, but watch recorded episodes

> How to organize that ? How to tell frontend on the desktop pc which backend I

I have done something similar here with two Backends, though I'll admit 
not an 'elegant' solution.  I have two Backends because of 'pixellation  
issues' -- really due to reception problems but that's a different 
issue.  Having a Frontend switch from viewing one Backend to the other 
appears to be more complicated than simply updating the configuration 
file to the alternate BE's IP and password: it appears when the 
configuration is changed the FE's audio and video configuration is reset 
to default, in other words instead of using a High Quality nVidia video 
setting it is changed back to the default generic setting.  Same for the 
audio.  The Theme preference also is resent to Terra (default).

What I did, which LIS isn't elegant, is use a Raspberry Pi B as my 
second Frontend.  The primary FE is a desktop with the output to HDMI1 
of the television.  The secondary FE is an RPi, configured to the other 
Backend, and whose output goes to HDMI2 of the TV.   (Told you it wasn't 
elegant!)

Now what I found is the RPi B and MythTV don't play nice all the time 
with the WiFi here at the house: some video and audio stuttering.  The 
good news is no problems with a wired connection. The computers around 
here are all hardwired so simply pulled an old 10/100 switch from the 
storage box to 'split' the Ethernet to the two Frontends.  Works fine!

Admittedly not quite what you had in mind but given for consideration as 
a different way to  accomplish the end.  I have no idea if the new PRi 
3+ has sufficient 'oomph' to work with MythTV; LIS my RPI 3 is right on 
the verge, so hopefully....
