/// # MPV_ERROR_SUCCESS
/// No error happened (used to signal successful operation)
/// # MPV_ERROR_EVENT_QUEUE_FULL
/// The event ringbuffer is full. This means the client is choked, and can't
/// receive any events. This can happen when too many asynchronous requests
/// have been made, but not answered. Probably never happens in practice,
/// unless the mpv core is frozen for some reason, and the client keeps
/// making asynchronous requests. (Bugs in the client API implementation
/// could also trigger this, e.g. if events become "lost".)
/// # MPV_ERROR_NOMEM
/// 'Memory allocation failed' error
/// # MPV_ERROR_UNINITIALIZED
/// The mpv core wasn't configured and initialized yet. See mpv.init()
/// for additional details
/// # MPV_ERROR_INVALID_PARAMETER
/// Generic catch-all error if a parameter is set to an invalid or
/// unsupported value. This is used if there is no better error code.
///
/// Typically this is sent when you are trying to set properties or options
/// where the value is not supported, but the format itself is
///
/// # MPV_ERROR_OPTION_NOT_FOUND
/// Trying to set an option that doesn't exist.
///
/// For a full list of options, see [here](http://mpv.io/manual/master/#options)
///
/// # MPV_ERROR_OPTION_FORMAT
///
/// Trying to set an option using an unsupported format.
///
/// ## Example
///
/// Sending a 'sid' value as a float.
///
/// Note that in most of the cases, when the libmpv option/property expect an integer
/// and gets a &str, it will try to convert the said str and a integer.
///
/// # MPV_ERROR_OPTION_ERROR
/// Setting the option failed. Typically this happens if the provided option
/// value could not be parsed
/// # MPV_ERROR_PROPERTY_NOT_FOUND
/// The accessed property doesn't exist
/// # MPV_ERROR_PROPERTY_FORMAT
/// Trying to set or get a property using an unsupported MPV_FORMAT.
/// See MPV_ERROR_OPTION_FORMAT for more details.
/// # MPV_ERROR_PROPERTY_UNAVAILABLE
/// The property exists, but is not available.
///
/// ## Example
///
/// This usually happens when the
/// associated subsystem is not active, e.g. querying audio parameters while
/// audio is disabled.
/// # MPV_ERROR_PROPERTY_ERROR
/// Error setting or getting a property
/// # MPV_ERROR_COMMAND
/// General error when running a command with mpv_command and similar
/// # MPV_ERROR_LOADING_FAILED
/// Generic error on loading (used with MpvEventEndFile.error).
/// # MPV_ERROR_AO_INIT_FAILED
/// Initializing the audio output failed.
/// # MPV_ERROR_VO_INIT_FAILED
/// Initializing the video output failed.
///
/// # MPV_ERROR_NOTHING_TO_PLAY
/// There was no audio or video data to play. This also happens if the
/// file was recognized, but did not contain any audio or video streams,
/// or no streams were selected.
///
/// # MPV_ERROR_UNKNOWN_FORMAT
///
/// When trying to load the file, the file format could not be determined,
/// or the file was too broken to open it.
/// # MPV_ERROR_UNSUPPORTED
/// Generic error for signaling that certain system requirements are not
/// fulfilled.
/// # MPV_ERROR_NOT_IMPLEMENTED
/// The libmpv API function which was called is a stub only
/// Note that unimplemented mpv-rs functions will simply panic with unimplemented!()
