Codec issue when playing from browser

[Skellum]

Apologies if this seems an obvious question

I am receiving a playback error when attempting to watch a TV Show on my browser.
Error is:
Stream mapping:
  Stream #0:0 -> #0:0 (hevc (native) -> av1 (av1_nvenc))
  Stream #0:1 -> #0:1 (eac3 (native) -> eac3 (native))

This appears to relate to the AV1 codec but I'm using a RTX3050 graphics card on my Jellyfin server which should support all formats and have been watching this show without issue on my TV.
If it relates to the device I am using then my computer uses a RTX3080 card and I have tried viewing the show in both Edge and Brave browsers.
Do I need to install codecs on my PC for the stream to decode? I presumed they would be built into my card software...

Thanks in advance.

Your card does not support encoding to AV1.  Disable it in your Playback Transcoding settings on the server.

Legend!

Thank you, I didn't realise that setting was even enabled. Working fine now.
