Might also fail with your graphics card. Not all graphics card support HEVC decoding. You can check it here: https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new
I have a GTX3080ti, I'm full green on that chart.
Firefox doesn't support HEVC decoding at all on Linux even using software decoding.
Firefox only supports HEVC experimentally on Windows through Windows Media Foundation. (Basically, Firefox itself does not provide the HEVC-related components. It only serves as a link for the Windows components that actually enable HEVC.)
They explicitly do not support it due to its patents (which means Mozilla would need to license HEVC, and, therefore, pay royalties/license fees).

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.
That's a 2017 answer that doesn't really cover the latest progress.

I've updated the README with a note on HEVC.
I am having trouble playing HEVC files in Firefox. Based on this project I feels like HEVC should be supported?
I am on Fedora 39 using X11, with Nvidia Driver 555.42.02. I have built the driver from the Master branch (was testing MPV, was the same on 0.0.12).
When attempting to play HEVC I see errors
