  /// Some API functions will return MPV_ERROR_UNINITIALIZED in the uninitialized
  /// state. You can call mpv_set_property() (or mpv_set_property_string() and
  /// other variants, and before mpv 0.21.0 mpv_set_option() etc.) to set initial
  /// options. After this, call mpv_initialize() to start the player, and then use
  /// e.g. mpv_command() to start playback of a file.
  ///
  /// The point of separating handle creation and actual initialization is that
  /// you can configure things which can't be changed during runtime.
  ///
  /// Unlike the command line player, this will have initial settings suitable
  /// for embedding in applications. The following settings are different:
  /// - stdin/stdout/stderr and the terminal will never be accessed. This is
  /// equivalent to setting the --no-terminal option.
  /// (Technically, this also suppresses C signal handling.)
  /// - No config files will be loaded. This is roughly equivalent to using
  /// --config=no. Since libmpv 1.15, you can actually re-enable this option,
  /// which will make libmpv load config files during mpv_initialize(). If you
  /// do this, you are strongly encouraged to set the "config-dir" option too.
  /// (Otherwise it will load the mpv command line player's config.)
  /// For example:
  /// mpv_set_option_string(mpv, "config-dir", "/my/path"); // set config root
  /// mpv_set_option_string(mpv, "config", "yes"); // enable config loading
  /// (call mpv_initialize() _after_ this)
  /// - Idle mode is enabled, which means the playback core will enter idle mode
  /// if there are no more files to play on the internal playlist, instead of
  /// exiting. This is equivalent to the --idle option.
  /// - Disable parts of input handling.
  /// - Most of the different settings can be viewed with the command line player
  /// by running "mpv --show-profile=libmpv".
  ///
  /// All this assumes that API users want a mpv instance that is strictly
  /// isolated from the command line player's configuration, user settings, and

  /// options.
  ///
  /// The mpv command line parser is not available through this API, but you can
