Disabling noise reduction RK3399

[BidonX99]

What parameter is responsible for disabling noise reduction RK3399 (on/off)? (Android 6 & 7)

ex. for AMLogic noise reduction:

/sys/module/di/parameters/nr2_en 

Where is Rockchip setting?
I want to disable via Init.d-script.

No such setting exist as there isn't noise reduction.
If you mean deinterlacing, that happens automatically.

Noise reduction really works in HW (It gives slight turbidity).
In SW mode it auto turns off.
If you compare the picture in SW and HW mode the difference is visible (on a good TV screen).

Description Rockchip:

Noise reduction RK3399

[B]Compression noise[/B] reduct ion with filter matrix up to 7x7.
[B]Compression[/B] [B]noise[/B] reduction with filter matrix up to 7x7.
Programmable difference table for compression noise reduction.
Programmable distance table for compression noise reduction.
Spatial sampling noise reduction.
Temporal sampling noise reduction.
Optional coefficient for sampling noise reduction.

Max resolution for dynamic image:
Sampling noise reduction: 1920x1080
Compression noise reduction: 4096x2304

Can you post 2 pictures to download I can compare with HW and SW playback where the difference is noticeable to see?
And also a sample video I can test.
Which video players did you use MXPlayer(probably), Media Center app or Kodi 18?
Maybe I can then find out about a way to add an extra setting to still use HW playback but reduce the amount of noise reduction taking place.

Hmm. In my opinion screenshots are identical.
Perhaps there is no capture 'Image Post-Processor' RK3399 (where is module 'Noise reduction').

I use only MXplayer.

You can clearly see how the picture changes when you switch HW / SW

(8-bit, gray background, Star Trek: The Original).

SW is sharper.
The same thing was on AMLogic, until I found de-noise module 'nr2_en'.
Though AMLogic had a very strong compression. At Rockchip it is much weaker.
