推荐答案
如何合并两个来源并在媒体播放器上播放它们.
How do I combine two sources and play them on the media player.
从语法角度来看,Source
属性只能设置一次,最后一次有效.因此,您的媒体将仅播放mediaSource_audio
中的音频.根据您的要求,您可以制作两个MediaPlayer
并使用 MediaTimelineController
可在多个播放器中同步内容.
From syntax point of view, the Source
property can only be set once and last valid. So you media will only play audio from mediaSource_audio
. For your requirement, you could make two MediaPlayer
and use MediaTimelineController
to synchronize content across multiple players.
mediaPlayer = new MediaPlayer();
mediaPlayer.Source = MediaSource.CreateFromUri(new Uri("ms-appx:///Assets/example_video.mkv"));
_mediaPlayerElement.SetMediaPlayer(mediaPlayer);
_mediaPlayer2 = new MediaPlayer();
_mediaPlayer2.Source = MediaSource.CreateFromUri(new Uri("ms-appx:///Assets/example_video_2.mkv"));
_mediaPlayerElement2.SetMediaPlayer(_mediaPlayer2);
_mediaTimelineController = new MediaTimelineController();
mediaPlayer.CommandManager.IsEnabled = false;
mediaPlayer.TimelineController = _mediaTimelineController;
_mediaPlayer2.CommandManager.IsEnabled = false;
_mediaPlayer2.TimelineController = _mediaTimelineController;
用法
private void PlayButton_Click(object sender, RoutedEventArgs e)
{
_mediaTimelineController.Start();
}
