Mozilla currently has no plans to support H.265. Our focus will be on AV1.

For some impressive VP9 results refer to https://www.twoorioles.com/eve-for-vp9

I understand you want to support the next generation codec AV1 but this is not an answer to your users who want support for current best codec available and widely used H.265.
x265 is an open-source implementation of H.265 / HEVC and is licensed under GPL v2 compatible with MPL 2.0 license so you can use this project to handle the hard work.
I see no reasons to ignore this feature.

[Jean-Yves Avenard [:jya]]

The reason we won't support H265 has nothing to do with the difficulty in finding a decoder, or that a decoder source code is released under GPL. Those are trivial matters.

We will not support h265 video while its patent encumbered.

BTW, even today vp9 provides better results than H265.

> I see no reasons to ignore this feature

I suggest you research about the h265 patent pools and the licensing model in use.

From what I can see, hevc is royalty-free specifically for browsers.

HEVC Advance is ONE patent pool, there's plenty more. MPEG LA pool is another, Technicolors etc...
All with their licensing policy.

Since there is a project https://github.com/StaZhu/enable-chromium-hevc-hardware-decoding use OS api to support HEVC on Win/macOS, can firefox use the same method?

Comment 11

[Tom Vaughan]

The request is not for Mozilla to provide HEVC video decoding in Firefox, which would require Mozilla to license HEVC. The request is to support (pass through) HEVC when the device supports it, as Safari and Chrome do. The device handles the video decoding, and as such, the device OEM is responsible for licensing all required HEVC patents. Device OEMs have been licensing and supporting HEVC for many years. As of 2018 the majority of mobile devices supported HEVC decoding... https://www.scientiamobile.com/growing-support-of-hevc-or-h-265-video-on-mobile-devices/.

I agree with this.

My question is if we should create a new ticket? This ticket is closed and therefore probably hardly noticed.

This is true. On the other hand developers often use filtered lists to get an overview of "TODO" tickets. Closed projects are usually filtered out.
