Constant libmpv_sys::mpv_event_id_MPV_EVENT_QUEUE_OVERFLOW

pub const mpv_event_id_MPV_EVENT_QUEUE_OVERFLOW: mpv_event_id = 24;

Happens if the internal per-mpv_handle ringbuffer overflows, and at least 1 event had to be dropped. This can happen if the client doesn't read the event queue quickly enough with mpv_wait_event(), or if the client makes a very large number of asynchronous calls at once.

Event delivery will continue normally once this event was returned (this forces the client to empty the queue completely).
