Hls dash is adaptive to resolution and image quality, hls is easy to obtain image quality, and dash is difficult to extract resolution and image quality, if you want to implement a button for users to switch image quality

dash.js is a chromeless player with a bunch of APIs. You need to add the UI. The library comes with a contributed UI that you can use that has almost an identical selector to what the youtube player offers. See https://reference.dashif.org/dash.js/latest/samples/getting-started/controlbar.html for example.
