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

(In reply to Johnny Stenback (:jst, firstname.lastname@example.org) from comment #1) > 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
Some background about AV1 https://www.youtube.com/watch?v=lzPaldsmJbk#action=share
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.
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. http://www.hevcadvance.com/pdfnew/Software_Policy_092017.pdf
HEVC Advance is ONE patent pool, there's plenty more. MPEG LA pool is another, Technicolors etc... All with their licensing policy.
