Description

Chrome 136+ supports the HEVC/H265 codec in WebRTC; see https://chromestatus.com/feature/5153479456456704.

This PR adds details of this to https://developer.mozilla.org/en-US/docs/Web/Media/Guides/Formats/WebRTC_codecs.

I searched around MDN, but didn't really see anywhere else where I should mention this.

@chrisdavidmills This is exactly the right place to update. One concern though. See https://developer.mozilla.org/en-US/docs/Web/Media/Guides/Formats/Video_codecs#hevc_h.265

I don't think we should just change that to "Yes" without some research as to whether this is a typo or something special is going on with Chrome.

Ah, I missed this table entry. Doesn't that just mean that support for it being used in WebRTC wasn't there before, but now it is so that we can toggle it to "yes"? I don't know what kind of special circumstances you might be referring to, but then again, I know very little about WebRTC.

I've asked the Chrome folks to look at this one in case of any specific information I need to include.

It doesn't say "works with" it says "compatible with". So asking the Chrome people what it takes to make a format compatible or incompatible with WebRTC and if there is such a distinction, how they got around it in this case is the right thing to do.

I suspect it does mean compatible with, but if that proves wrong we can change the docs. I know someone we can ask in FF land if you need me to.
