farchord commented 5 months ago

This patch was originally created by @Zamundaaa in the #kde-sig channel in Matrix. This patch enables viewing of HDR videos on systems that supports it.

This feature was set to only function on ChromeOS. This patch undoes that.

This has been tested as working on Wayland with the ozone flag set to Wayland as well.

Or, at the very least, the HDR logo could be seen on youtube videos. The color is still off, but that's something being worked on on KDE's side.
