Help with "Extra priority" usage

Added by wet willy about 12 years ago

Hello dear Tvheadend developers.

I just installed 3.2 beta(HTS Tvheadend 3.1.743~g7687dd4) and it's looking really good.

Currently I'm using one pci tuner and one usb tuner where the pci one works better than the USB so I would like to use the pci one primarily.

I took a look at the Help text and it says the following about Extra priority:

"Extra priority
This field can be used to define a priority ordering for adapters. This will be used when determining which adapter to use to service a subscription request. It could be used for example to prefer a DVB-S adapter over a DVB-T one."

So how should I proceed in order to give my pci tuner extra priority? Is it supposed to be used the same as routing metrics where a lower value equals a higher priority e.g. my pci tuner should be left at 0 and the usb >=1?

Or is it the other way around? :) eg, leave my usb at priority 0 and the pci >=1?

For the stable release it might be a good idea to specify the usage in the help text, but I read that there would be focus on the documentation so I'm sure you already got it covered!

Keep up the good work!

If you simply want to prioritise PCI over USB you don't need to. TVH has an inherent prioritisation based on the bus type of the adapter, PCI should by preferred over USB by default.

The extra priority is more for overriding this and to select between adapters using the same bus type, i.e. you might prefer a (PCI) DVB-S over (PCI) DVB-T because of the high bandwidth available on S for example.

Alright. That clears things up :)

Thanks for your reply Adam!

Wading in for the sake of completeness.... if you do have two adapters of the same bus type, then, how would you prioritise them? Any clues?

From what I can see on other posts, it's the LOWEST numbered adapters that have the HIGHEST priority - correct? So, you de-prioritise an adapter by raising the "extra priority" value...

I believe that explanation is indeed correct, the field is somewhat backwards. And I've just spotted a bug in my code ;)
