Video color looks strange

[danielcy]

Hi, I'm using screen sharing in my WebGL project. Everything works fine except the color of the video.
The origin picture looks like this:

And when I share this in my game, it looks like this:

My Unity version is 2021.3.12f1c2, using URP, and this is my video config:

_mRtcEngine.EnableVideo();
_mRtcEngine.EnableVideoObserver();
_mRtcEngine.EnableDualStreamMode(true);
VideoEncoderConfiguration config = new VideoEncoderConfiguration
{
degradationPreference = DEGRADATION_PREFERENCE.MAINTAIN_FRAMERATE,
mirrorMode = VIDEO_MIRROR_MODE_TYPE.VIDEO_MIRROR_MODE_DISABLED
};
_mRtcEngine.SetVideoEncoderConfiguration(config);

I've tried lots of things including change the config, adjust the shader ... but nothing good.
Really appreciate if anyone can help me or explain why this happend.
Thanks

Hi, we got the same questions from other people and it seems to be true this is happening on screensharing. Somehow I don't experience this on my setup. Can you do another test? Compare the output of the WebGL output to the regular webdemo's out put. And see if there is any difference?

I have similar color issues on web cam feed as well and the problem in my case is using linear color space.
I suspect @danielcy is using linear color space as well.

If you just change the color space from gamma to linear in the demo project, you'd experience this.

The issue has been addressed in Refactor 8 release. Linear color space matches the true color now.

Colors are a bit darker in play mode in the editor, however it is kind of faded in the webgl build. We can't change the color space to gamma because it messes up our lightmaps. Is there any other solution?
