MPV_EVENT_CLIENT_MESSAGE constant
int
const MPV_EVENT_CLIENT_MESSAGE
Triggered by the script-message input command. The command uses the first argument of the command as client name (see mpv_client_name()) to dispatch the message, and passes along all arguments starting from the second argument as strings. See also mpv_event and mpv_event_client_message.
Implementation
static const int MPV_EVENT_CLIENT_MESSAGE = 16;
