Please add advanced prescale options in Kodi, like those that are available for mpv player or mpdn.

For example:

Super-xBR
NNEDI3 (Neural-Network Edge-Directed Interpolation)

These prescalers are especially nice for old DVDs, or when upscaling bluray to a 4k TV. There are more prescalers available (f.e. NEDI), but those two are the most commonly used.


For more information, take a look at this commit for mpv:
https://github.com/mpv-player/mpv/commit...4e5e9c2efb
or at the MPDN extensions github:
https://github.com/zachsaw/MPDN_Extensions


The option to activate the prescalers could be added as an expert option under "Settings -> Video Player -> Processing", for example like:
"Double video image resolution" -> Options: "Off" | "Only if required" | "Always"
"Algorithm for image resolution doubling" (greyed out suboption/only available if Double video image resolution is checked) -> Options: "Super-xBR" | "NNEDI3 (16 Neurons)" | "NNEDI3 (32 Neurons)" | ...

In the description, warn that these shaders are compute extensive and should only be activated when using a dedicated graphics card. For example:

"Use image doubling scalers for upscaling the video. These scalers can only upscale the original image by a factor of two. Useful for upscaling DVDs or Bluray to 4K. A modern, dedicated GPU is required.

These options should only be added for generic linux / windows builds. not be added for raspberry / android, since they lack the compute power.

Please add the SSSR upscale shader from MPDN to Kodi

"The aim of this shader is to make corrections to the upscaled image. Works with regular scalers only, not prescalers."

Available in MPDN extensions and as a mpv user script. For more information:

Is there a legit reason to open a 2nd thread for recommending/requesting upscale shaders?

No there is really not, I have joined the requests together.
This makes it easier for someone to find those references in case they are interested in attempting this for Kodi.
