Problem
thorium-browser will no longer playback HEVC videos. Tested using https://thorium.rocks/misc/h265-tester.html
Tested latest google chrome, and it works, although without sound.

https://thorium.rocks/misc/h265-tester.html works for me using latest Thorium (M126).

You use

Thorium Version 122.0.6261.132

Please update and try again.

Same here it doesnt work on Windows with latest thorium build

Odd, i was sure i was running the latest version. In any regard, i removed 122, deleted all cache files and directories (.cache/thorium & .config/thorium) installed 126, but the problem persists.

@midzer @genesis224 @thnkman I am not able to recreate this on any of my machines. I have one with a core 2 duo and integrated graphics, a 4th gen laptop with AMD graphics, and my main system with nvidia graphics. Two of those have no hardware HEVC decoding support, which is what Thorium's patches are for, to allow HEVC and AC3 no matter what, falling back to software FFMPEG decoding if needed.

I can play HEVC videos on test sites, as well as the AC3 test files on my site.

Then i am at a loss. Thanks for checking.

@thnkman Are you using the regular AVX build? Because I think I may have found why
