A little script for the mpv to set preferred audio and subtitles for a folder of video files at once.
Drop per-folder-tracks.lua into your scripts folder.
Press y to write current audio and subtitles track ids to a file .mpv located in the folder with the currently playing video.
Keybind and filename are set at the top of the script — the very first assignment statements, should you wish to change them.
If the file is present, previously set tracks will be restored for any video file from the same folder, if possible.
Note
Matching is done only by number as it appears in the player UI, not by track name, language, or anything else. For best results, make sure that all videos in the folder have same audio/sub tracks.
If the script is unable to set the saved tracks (malformed file or missing tracks), it will show an OSD message, and a detailed error message to the console.
Let's suppose that for some reason there is a folder, where several video files are stored. These videos all have multiple audio and subtitle tracks, with same languages having same track ids.
Let's suppose that we want to play these files with non-default audio and subtitle tracks. With this handy script, you can open one of these files, change the tracks once, hit y (default) to save the selection. You can then enjoy watching the videos without ever having to switch "Signs&Songs" to "Full" again! (for this folder)

The original video files are not modified. To remove track preselection, simply remove the file created by the script.
This is a quick and dirty script to automate my own tedious clicking, so be aware of the following:
- It is only have been tested on local files on GNU/Linux.
(I don't know whether or not will it work with other video types and/or operating systems.) - It only provides a way to set audio and/or subtitle tracks with little error proofing.
(It is not a tool to store any other settings for the player. The filename may be misleading, but i couldn't come up with a better one. See script's comments for some of the shortcomings.)
Basically, works on my machine. Have fun.
