[Question] How to show MPV's builtin STATS programingly

[CarterLi]

IINA uses libmpv as its backend and we want to toggle showing mpv statistics. I can't find any options / commands to do it except --load-stats-overlay which doesn't seem to be useful

Can I send keyboard events to libmpv?

Can I send keyboard events to libmpv?

iiana can, I don't know whether it allows users to send them to mpv.

As for stats.lua, it can also be activated using script-message. See the "Different key bindings" section at the stats docs, though again, I don't know if iiana has a way to allow users to send script-messages to mpv.

I'm one of a developer of IINA and I'm searching for method to communicate with libmpv using various options / commands. Sorry for confusion.

Can I send keyboard events to libmpv?

iiana can, I don't know whether it allows users to send them to mpv.

I mean if I can forward keyboard events to libmpv somehow.

As for stats.lua, it can also be activated using script-message. See the "Different key bindings" section at the stats docs, though again, I don't know if iiana has a way to allow users to send script-messages to mpv.

IINA don't uses MPV's native window but IINA creates its own, so MPV won't receive users' keyboard events directly. We have to forward these keyboard events to libmpv using libmpv's API somehow. I want to know if there are APIs for that.

As for script-message, I still don't know how to use it. Any examples?

The simplest way for both would probably be with to send a keypress KEY and/or script-message MESSAGE ARG... commands to mpv.

There are other ways. client.h is documented quite well, and so are the available mpv commands (at the mpv docs).

Sorry, script-binding, not script-message. E.g. script-binding stats/display-stats-toggle (as seen at that docs section.
