Auto select less compressed option

[GLPG35]

describe the feature you'd like to see

When using the website, I notice that in the options, you can select manually between h264, av1 and vp9, but there's no "auto" option.

What I mean with that "auto" option is just that sometimes YouTube offers av1 and vp9 codecs, but av1 could be just vp9 encoded into av1, and it's not the best quality, so it would be nice to detect automatically the less compressed codec from the source, as for example, yt-dlp does.
