Jellyfin 10.11.2 transcode

[alucardnos13]

Hello, 

am running the latest version of jellyfin on my server and devices (tablet, firetv)

Most of my videos are encoded into AV1 with handbrake.
When i play these files through jellyfin app they are on directplay

When i open through web browser from my computer or tablet then it tries to transcode the files. I disabled transcoding and remuxing and they dont play at all, i then enabled only remuxing and they play.

Why does it have to remux when running from browsers on my phone, pc? Video is AV1 main profile on handbrake and audio is AAC stereo.
If i try to play it from my phone using jellyfin app instead of web browser its direct playing. 

H264 files with the same aac audio are direct playing in browser.
I use the latest versikn of chrome and firefox to test

I am accessing my jellyfin server remotely using cloudflare and caddy

After checking the logs i saw that container is not supported and thats why is remuxing.
I thought that chrome and firefom are fully compatible with AV1 mp4
