Using the library without `winit::event_loop`

[aome510]

Hi, I'm trying to use this library in MacOS Monterey 12.3.1.

Running examples/print_events doesn't work (no media event printed even when I press one, no metadata shown up in the media control). Running example/example.rs works perfectly but I'm not sure I understand the requirement of winit library here. winit and winit::event_loop seem to be the only difference between examples/print_events.rs and examples/example.rs

Does souvlaki work without winit, as I see that winit is only included as the devdependencies? Am I missing something here?

Hi. To run in Windows, souvlaki needs a raw window handle also known as HWND. In MacOS and Linux, a window handle isn't required, so the print_events example should work. That's weird. I can't comment much on the MacOS implementation since I didn't write it (@jpochyla). Maybe it has to do with the thread being blocked. Can you try opening the media controls in another thread and/or reducing the sleep time?

Media control is only available for window processes on MacOS.

Still not work AFAICT. I guess the reason is because MacOS needs an open window to listen to the events, as other mentioned.

Will close this issue for now. Thanks.

I'd appreciate if someone with access to MacOS could pin down the behaviour of media controls and window processes, so it can be stated in the crate's documentation and prevent misunderstandings. I'm going to put a warning in the docs for now.

From my experience with a NodeJS library I used with Electron (electron-media-service), it is likely that an application event-loop is required (i.e. Winit's event_loop), but a window itself is not strictly required (as it is common for Mac OS applications to continue running despite no open windows, the event loop would continue anyway)

I think the specific requirement would be a running AppDelegate, regardless of the existence of any windows.

(This also requires that the code be running on the main application thread, as Mac OS doesn't support having the AppDelegate on another thread)
