Native software-based AV1 playback in Plex on Apple TV 4K

To enable native AV1 software decode in Plex on Apple TV 4K you have to add your own xml to override on the server side.

You need to find the «Application Support/Plex Media Server/Profiles» folder and put the xml file there.

Apple TV 4K has a very powerful cpu that can software decode 4K30 HDR AV1, it can also to my surprise decode the Opus audio codec.
