youtube-quality

A userscript for MPV that allows you to change youtube video quality (ytdl-format) on the fly, as though you were using the web player.

Toggle the menu with ctrl+f (configurable). Select from the list with the arrow keys (configurable), and press enter (configurable) to select. Menu times out after 10 seconds (configurable.)

Installation

Copy youtube-quality.lua into your scripts directory, e.g.:

cp youtube-quality.lua ~/.config/mpv/scripts/

optional, copy the config file:

cp youtube-quality.conf ~/.config/mpv/script-opts/

OSC extension

Completely optional, an extended version of the OSC is available that includes a button to display the quality menu. To use this, copy the youtube-quality-osc.lua file into your scripts directory and put osc=no in your mpv.conf.

PLEASE NOTE: This conflicts with other scripts that modify the OSC, such as TheAMM's excellent mpv_thumbnail_script. Merging this OSC modification with that script or others is certainly possible, but is left as an exercise for the user...

Plans For Future Enhancement

• Visual indication of what the current quality level is.
• Option to populate the quality list automatically with the exact formats available for a given video.
• Optional OSC extension.

Credit

• reload.lua, for the function to reload a video while preserving the playlist.
• mpv-playlistmanager, from which I ripped off much of the menu formatting config.
• ytdl_hook.lua, from which I ripped off much of the youtube-dl code to fetch the format list
• somebody on /mpv/ for the idea
