MediaPlayer.MediaPlayerRateChanged 事件

定义

在媒体播放速率更改时发生。

注意

MediaPlayer.MediaPlayerRateChanged 可能在Windows 10版本 1607 之后更改或不可用。 请改用 MediaPlayer.PlaybackSession 属性获取 MediaPlaybackSession 对象,然后使用 MediaPlaybackSession.PlaybackRateChanged 事件。

// Register
event_token MediaPlayerRateChanged(TypedEventHandler<MediaPlayer, MediaPlayerRateChangedEventArgs const&> const& handler) const;

// Revoke with event_token
void MediaPlayerRateChanged(event_token const* cookie) const;

// Revoke with event_revoker
MediaPlayer::MediaPlayerRateChanged_revoker MediaPlayerRateChanged(auto_revoke_t, TypedEventHandler<MediaPlayer, MediaPlayerRateChangedEventArgs const&> const& handler) const;
