problem when setting the watch-later-directory using an auto-profile

[S-Aarab]

I'm trying to set a different watch-later-directory for different websites (YouTube, for example) using auto-profile.

/tmp/mpv
 ├──  watch_later
 ├──  yt_watch_later
 │   └──  EF2F1F0F986057AEA98BE516743E1DBD
 └──  config

/tmp/mpv/config

[default]   
watch-later-directory = /tmp/mpv/watch_later
save-position-on-quit = yes
    
[youtube]
profile-cond = get('path', ''):find('^https://www%.youtube%.com')         
profile-restore = copy
watch-later-directory = /tmp/mpv/yt_watch_later

mpv --config-dir=/tmp/mpv --log-file=log.txt 'https://www.youtube.com/watch?v=tlsGQKSL1K4'

log.txt

The problem is that by the time the property path is available and the auto-profile can be applied, it's too late because MPV has already run the resume logic using the default watch-later-directory and didn't find any resume config file.

How can I solve this? the perfect solution will be:

• Make the resume logic wait for the path to be available.
• Re-run the resume logic whenever the property watch-later-directory changes.

Maybe I'm missing something, any help/solution for this?
Thank you.

I managed to solve this problem by using a Lua script that retrieves the current playlist's filename, as it is available earlier, and uses it instead of the path, since both have the same value.

mp.add_hook('on_before_start_file', 50, function()
    for _, entry in ipairs(mp.get_property_native('playlist', {})) do
        if entry.current then
            mp.set_property_native('user-data/playlist_current_filename', entry.filename)
            break
        end
    end
end)

mp.add_hook('on_after_end_file', 50, function()
    mp.set_property_native('user-data/playlist_current_filename', nil)
end)

[default]   
watch-later-directory = /tmp/mpv/watch_later
save-position-on-quit = yes
    
[youtube]
profile-cond = get('user-data/playlist_current_filename', ''):find('^https://www%.youtube%.com')         
profile-restore = copy
watch-later-directory = /tmp/mpv/yt_watch_later

There is one important point to note: profiles that use user-data/playlist_current_filename will always be applied before those that use path, regardless of the order in which they appear in the config file. Please keep this in mind.

For now, this solution meets my needs. If you have a better alternative, please feel free to share it. Thank you.

Just a note: As of version 0.40.0, auto_profiles uses mp.add_hook with a priority of 5. You need to adjust the Lua script above to use the same priority or a higher one.

mp.add_hook('on_before_start_file', 4, function()
