mpv-createchapter VS mpv-quality-menu

createchapter.lua: this one might be handy if you want to create chapters at certain point of a video.

acompressor.lua: compressor. blur-edges.lua: fills the black bars on the side of a video with a blurred copy of its edges. createchapter.lua: self-explanatory. crop.lua: crop video in a visual manner. encode.lua: make an extract of the video currently playing using ffmpeg. reload.lua: reloads videos if an online video stops caching. seek-to.lua: go to timestamp. simplehistory.lua: stores whatever you open in a history file. skiptosilence.lua: skip past "previously on...". smartcopypaste_ii.lua: copy/paste links sponsorblock.lua: skip sponsors in yt videos. streamsave.lua: save looped section to a separate file. subit.lua: download subtitles to playing video. uosc.lua: feature-rich minimalist proximity-based ui (my fav!). webm.lua: similar to encode.lua but with more features and no external dependencies. webtorrent-mpv-hook: enable mpv to stream torrents using webtorrent. youtube-quality.lua: change quality of currently playing yt video.

you can create chapters with this script https://github.com/shinchiro/mpv-createchapter

here this is what you want I think

Every other script has dropped in and works instantly other than this one, no matter what I do the menu never loadsm or gives any indication of loading. The old, outdated youtube quality script loads, but presumably because of changes to youtube it fails fetching the list of formats. The menu does still show up.

first you should probably stop using the ancient version of that script and use https://github.com/christoph-heinrich/mpv-quality-menu instead. this one works on all sites for me, as long as they actually have quality options. youtube, twitch, vimeo, etc
