[Video playback] Video player's colors are off from file version

[gm-bug-reporter]

Description

When trying to play videos through the video player, everything seems to be fine but the colors are different from what I expected, oranges were really yellow while blues were darker. Images provided shows the expected version in image2 and the gamemaker version in image.

Here's other dev reporting the same issue:

An example may be helpful, here's the same png as an asset/sprite vs played as a video after conversion to mp4

Yep, this is a serious problem. Here's a colour bars comparison. The first file is the original and the second is how GameMaker is rendering.

This is made with the most vanilla export humanly possible: 1080p h264 mp4 from Premiere with all standard settings.

Can confirm this issue, I'm hoping it's a simple enough fix to get this out of the backlog- I can also confirm the video works great in YUV formats on console, it's just the RGB playback that's bugged.

As a temporary fix for my stuff, I figured out the colour change that is being done and we have exported our video with another filter that reverses it. Ive put the equations for the rgb values here . They aren't exactly correct but generally they are close enough, this wont work for values that go out of the 0-255 range as well.

Hopefully it is useful for others

This seems to have been fixed in runtime 2024.11.0.227 (tested on Windows and macOS).
