Is there a way to reload uosc without relaunching mpv?

[SherLock707]

From pywal I'm updating the colour in ~/.config/mpv/script-opts/uosc.conf and wondering if there is a way to reload uosc without killing active player via cli.

[tomasklaen]

We do listen to on_update event of options.read_options (search for it on https://mpv.io/manual/master, links to headers don't work), which enables runtime updates.

But I don't think mpv is listening for file changes. uosc certainly isn't.

[SherLock707]

Don't need to listen to changes, any manual refresh command will do too.

[tomasklaen]

Then just change script opts at runtime and it should propagate to uosc.

[SherLock707]

How to set this in runtime?
color=foreground=ed939d

[tomasklaen]

set script-opts uosc-color="...colors, see uosc.conf docs..."

[SherLock707]

Looks like can't send commands from external terminal to set these. Thanks.

Thanks! This helped immensely.

I ended up launching mpv with socket with input-ipc-server=/tmp/mpvsocket in config and setting colour from external script via that socket as echo '{ "command": ["set", "script-opts", "uosc-color=foreground=ea76cb"] }' | socat - /tmp/mpvsocket

[mrfragger]

This works too saving theme to uosc.conf and also showing immediate change. Mac or Linux should work.

yes, I have a script that does this everytime a new colour scheme is generated. By socket I can set to already opened widows too which is what I was looking for. thanks.

[mrfragger]

yes I'm aware with socket....mostly over my head but I get it's function ..allows reading input and passing arguments via the command line interface. Mainly was just posting in case others might have use of it. Same with this lua script.

Here's the script I now use. Say one likes a style, font size, font, colors, etc. so they set it to be default. Then everytime they open new audio/video it'll be that font/ style. But if one opens a playlist and switching to new media keeps it to the current font /style so this allows one to apply the default font/style that's set in mpv.conf

edit: removed sub-back-color as it's an alias for sub-shadow-color

say I set default style /font

so it saves the values in mpv.conf

then I switch to another font/color style I can easily revert back to my default / favorites font/color style
