MPV how do you change the default window size?

[frekac]

Have been trying to get MPV to start with a different initial window size but all attempts have failed.
It almost seem like it's a floating window issue, e.g. Bitwarden starts with the exact same size 875x600.
Have used hyprctl clients to check the sizes.

Have tried editing the mpv.conf.
E.g. volume=xx works but not geometry or autofit.

Have created a windowrule.conf and sourced it in ~/.config/hypr/hyprland.conf
The rule looks like this (have tried different variations and none have worked):
windowrule {
name = resize-mpv
match:class = mpv
float = on
size = 1920 1080
center = on
}

Have tried using that rule in the default .conf file locations as well.
But so far nothing have changed the size of the window.
Have found a similar issue here but in regard to Steam.
But don't want to mess that discussion up if it's unrelated.

Any help appreciated.

Found a solution to the problem.

Seem like the steam size settings were getting used if I edited the steam.conf file.
So I compared the "hyprctl clients" output from both mpv and steam.
With mpv there was an extra tag called "floating-window*" that was not present in the steam output.
Added a line in my windowrule.conf file to remove the tag and voila!

For anyone that stumble upon the same problem here is an example of my windowrule.conf file for mpv.

windowrule = tag -floating-window*, match:class mpv

windowrule {
    name = resize-mpv
    match:class = mpv
    float = on
    size = 1920 1080
    center = on
}
