Regarding Hyperion issue about too dark v4l2 grabber image, some hyperion team members say (here the complete thread):

Maybe the defaults have changed in the kernel drivers in 18 ?

Can you use something like v4l-ctl to adjust brightness and contrast ?

----

You need v4l-utils package installed afaik:

https://github.com/LibreELEC/LibreELEC.t.../v4l-utils

To install that should be these commands run from the Libreelec SSH shell:

Codeudo apt-get update
sudo apt-get install v4l-utils
afterwards v4l-ctl will be present as that is part of the utils 

As to the cause I'm not entirely sure, best guess:

- Default brightness / gamma changed in LibreElec test build for grabbing devices which v4l-ctl can correct but not ideal.
- Kodi 18 defaults to 10bit and doesn't play nice with 8bit readouts (losing brightness as a result)

@Milhouse I don't know if this is something you can fix or take a look, and I am sorry if this is not related with your work.
Thanks.
