I tried with your OpenELEC, and the result is similar to Kodi nightly:
OpenELEC full range: link
OpenELEC limited range: link

Settings: VAAPI, no dithering.

And now turn off vaapi please. What happens?

And enable VDPAU or only software decoder?

I tried with both settings:

Kodi nightly software decoder: link
Kodi nightly VDPAU: link

And yes, the details are fine, only VAAPI softens the picture.

Cool. Please apt get install mpv and play it with that player with -vo vaapi Parameter. Paste the terminal output please, same issue?

Are you sure, that you start that from a running desktop with the user logged in? The procedure is as follows:

a) Find out, that other players that use VAAPI decoding are also affected xor are not affected.
b) If all players you tested are affected, file a bug with the VAAPI people on bugs.freedesktop.org where you provide the screenshot comparison. They then will ask you to test with gstreamer.

If you followed my howto in post 1 - the user is "kodi" and it has to be in the video / audio group. if you cannot connect to the X display then you have configuration issue on top.

Edit: And something else to care for irritated users: VDPAU obviously works cause it won't open on intel gpus and kodi falls back to SW - so VDPAU is the same as SW decoding on intel vaapi hardware.

I'm not a linux expert, but I followed the guide from first post, I tried with superuser, but the error is same. I'm sad because we could not solve the problem, and I will sell the hdmi capture device tomorrow.
I hope, somebody will improve the VAAPI picture quality, because so linux htpc not an option in quality...

As your user is NOT kodi you did not follow the howto from post 1 ...

Also: Post the sample (in that format it is now) you are using for testing somewhere, please. If it is too large, use dd to cut out a 50 MB part, e.g.

Code:
dd if=yourmovie.mkv of=50mbsample.mkv bs=1M count=50

You can retry to use mpv with:

Code:
mpv --hwdec=vaapi yoursample.mkv

There are plenty other things to test ... like disabling VAAPI Output in Video-> Acceleration

So please also try: Video -> Acceleration: Prefer VAAPI output disabled

djnice · 2016-05-12, 10:58

The Video -> Acceleration: Prefer VAAPI output disabled is solved the problem!

Thank you very much! This let's us investigate the issue. So it's not a decoder issue, but a rendering issue.

djnice · 2016-05-12, 11:22

Thank you!
This is the sample file: link

When is it expected to improve this issue?

Next year - currently moving, not working on kodi at all.
