Just tried ur tweaked Version but it doesn't work for me, if i enable va-api i get a way too dark picture
as usual with Full RGB Enabled and nothing else.. :/

True. Just tried with RGB Full. There is no change.
But the change is visible on RGB Limited. I dont know, but think that the aim should be RGB Full I am wrong here?

Black levels shouldn't have changed with this as they seemed correct before. Maybe your screens are set to display blacker-than-black (levels under 16)? [another edit: actually if the picture is too dark, it sounds like your screen expects limited range]

To troubleshoot your problems:

1) Figure out which RGB range your TV expects. Use a bluray player or any other media source that you can use to play calibration patterns and set to RGB output. I suggest using AVSHD709 for patterns. Check with the basic tests that you have working settings either in full range or limited range. Make sure your source is set for neutral brightness/contrast. Take note of the lowest and highest visible values.

2) Use xrandr to select full or limited range, same as you used above.

3) Check black levels on xbmc using the same patterns. They should match.

If your black levels don't match between steps 1 and 3, please report your reference device and the highest/lowest visible with each device.

At the moment, it is not possible to get blacker-than-black (under 16) or whiter-than-white (over 235) with VA-API decoding. They are clipped by the colorspace conversion. If you need those, you will have to use software decoding for now.


edit: Crssi: it doesn't matter if you aim for full or limited range at the moment. Use whichever your display defaults to. If you can set it to either, use full.
