I've disabled the ambient light in 3D/VR videos since 2019 because there was no way to capture the image from a 3D video. But it might be worth investigating it once again.

So far, I've got it partially working.

Firefox displays nothing, but Chromium browsers work sometimes:

But after navigating to another VR video (or sometimes just randomly after a while) the image data becomes corrupted:

Apparently the corrupted image data on Chromium browsers only happens with the ANGLE flag set to D3D11on12.

Todo:

• [x] Bland (incorrect?) colors. The ambient light has to be drawn only when the VR video's webgl drawArrays function is called
  • [x] Navigating from a hidden tab to a visible tab
  • [x] When the VR video is being rotated while it's paused
  • [x] Seeking through a paused VR video
  • [x] Resizing the browser window when the video is paused
  • [x] Changing a setting corrupts the image data (Fixed some times, could not be fixed completely)
• [x] Setting the framerate limiter pauses the ambient light
• [x] Setting: Enable in VR videos
• [x] Disable framerate limiter setting on VR videos
• [x] Doesn't work yet on Firefox, exclude support?
