播放整个视频中的3秒片段

Question

我有一个10秒长的视频剪辑，我想从3秒播放到6秒。使用CCPlayer可以做到这一点吗？或者甚至是MPMoviewPlayer？

这是我的代码：

MPMoviePlayerController *_theMovie;  
[_theMovie setCurrentPlaybackTime:1.0];  
[_theMovie setEndPlaybackTime:2.0];  
[_theMovie play];  

但视频播放时间为0到2秒:(

谢谢

Answer 1

这是docs中的两个setter。

// The start time of movie playback. Defaults to NaN, indicating the natural start time of the movie.
@property(nonatomic) NSTimeInterval initialPlaybackTime;

// The end time of movie playback. Defaults to NaN, which indicates natural end time of the movie.
@property(nonatomic) NSTimeInterval endPlaybackTime;


MPMoviePlayerController *_theMovie;
[theMovie setInitialPlaybackTime:3.0]; //instead of [_theMovie setCurrentPlaybackTime:1.0];
[theMovie setEndPlaybackTime:6.0];
[_theMovie prepareToPlay];
[_theMovie play];

在MPMoviewPlayer中更改currentPlaybackRate时间，

moviplayer.currentPlaybackRate =moviePlayer.duration/3 or  6;
