I have a laptop with limited decoding capabilities with regards to royalty free formats, which YouTube tends to use, but I do prefer the quality that I get out of av1/vp9 encoded content on YouTube when using those on my home PC over what I get through h264ify.

What I do have, is a server which runs Jellyfin and can transcode content just fine. Is there any software I could host which could transcode videos I watch with a browser extension via my server?

Sorry if this is jumbled or unclear but it’s something that I would really have a use for, and if feasible, would even write myself.
