Does Opera GX support HEVC (H.265) video playback?

Hi!
I'm trying to switch to Opera GX, but I'm having trouble with videos encoded in HEVC (H.265). When playing media from my Jellyfin server, the browser forces transcoding.
On other chromium based browsers like edge or chrome everything works just fine.

On Windows, Opera uses the Windows Media Foundation for proprietary codec (like h.264) playback. So, the first requirement would be for Windows itself to support h.265 (via https://apps.microsoft.com/detail/9nmzlz57r3t7?hl=en-US&gl=US and not some direct show codec). However, even then, I don't know if Opera will take advantage of it or not. I don't think it does.
I'm on Windows 11 23H2 and Chrome for example doesn't play https://test-videos.co.uk/vids/bigbuckbunny/mp4/h265/1080/Big_Buck_Bunny_1080_10s_1MB.mp4 for me. Edge doesn't play it either. I don't have the h.265 codec from the store installed though.
Things might be different on macOS.
Vivaldi usually does the same as Opera in these cases.

Sorry for not replying earlier. Unfortunately, at that time I didn’t have enough time to investigate the issue further. From what I observed back then, the problem didn’t seem to be the codec itself, but rather the combination with container format, specifically MKV.
I found a set of browser test files at the time, and after running some tests I came to these conclusions. That’s where I left the topic, and in the meantime I changed my computer and reinstalled the operating system.
Today, out of curiosity, I played the video in Jellyfin and it turned out to work
It’s possible that the issue was actually on my side.Thanks for the replies.
