How does Jellyfin-web determine what content a client is capable of playing?

Yes, I did, read the OP please.

A quick test shows probably for both 1.1.0 versions

Code:

var video = document.createElement('video');

types = [
    'video/mp4; codecs="hvc1.1.L120"',
    'video/mp4; codecs="hev1.1.L120"',
    'video/mp4; codecs="hvc1.1.0.L120"',
    'video/mp4; codecs="hev1.1.0.L120"'
    ];

types.forEach((t) => console.log('testing ' + t + ' ' + video.canPlayType(t)));
