HEVC playback on web

[Turbofiero 5]

This used to work fine, im not sure what happened over the past year or so, but it would seem I can no longer direct play HEVC content despite having the codec installed and edge://media-internals CDMs do show hevc listed...

Suggestions? Issue is present on any device even ones that do have hevc support

Hi there, have you explored the stats feature in the video player to learn why a conversion was taking place?

[Turbofiero 5]

It said codec not supported, but I have found the culprit

HEVC playback has been broken on edge since 117... downgrading to 116.0.1938.98 has resolved all HEVC related issues

[Luke 42081]

Do you have the windows store hevc extension installed? 

[Turbofiero 5]

Yup, otherwise the copy/paste up there from edge://media-internals wouldnt have hevc listed

FWIW Having no issues with HEVC (8-bit or 10-bit) and AAC/AC3 audio DirectPlaying on Edge 117.x (Win 10).

interesting, this version doesnt work for me, and http://ott.dolby.com/codec_test/index.html indicates you have h265 support? What version of the HEVC Video Extension from the ms store are you running? Wonder why its working for you and not me... others seem to be having issues with av1 as of version 117.x

Thanks for the screenshots!

Issue seems to be present on another machine but instead of hevc breaking on version 117 on this other machine 120 breaks it

Very odd... I wonder if you were to update to 120, would hevc still work

Have no provisions to update it for at least another month or so, so not much help for you there. 

Either way, I keep other browsers (MS Edge, Chrome, Firefox) installed and occasionally updated just for forum support, Chromium Marmaduke is my web-player of choice, you might wanna give it a spin and see how does that compare.
