No black borders on AMLogic platform input

• [x] I confirm that this is an issue rather than a question.

Bug report

It seems the image is grabbed before black borders (or Kodi UI elements but that's probably a different issue) are added, then resized to whatever size is setted in the config. So one can't disable black border detection and if they are there the LEDs are off cause stretched on one axis.

Steps to reproduce

1) Disable black border detection 2) play a 4:3 video on a 16:9 screen or vice-versa

What is expected?

LEDs at the black borders stay off.

What is actually happening?

Hyperion is ignoring the black border.

@Portisch Can you say something about that?

[Portisch]

A bit late but I tested it now. On CoreELEC 19.2_Matrix-rc2 and alpha.9

I think it's a issue of the grabber as it get stretched in the Webinterface:

@V10lator Can you re-test with alpha10 and report back please, if the issue is still present?

[V10lator]

It's still the same with alpha10.

Made a photo showing the issue. This is with black border detection disabled:

Actually, this issue belongs in the feature request corner. Since the AMLogic grabber captures the video source material and not the screen, no black borders can be detected because there are none. If the video source material is encoded with black borders, everything should work as intended. I see that the next thing is that black border detection does not work with AML grabber and 16:9 videos on 4:3 output devices. I will close here. Please make a feature request. Thanks
