iphone - 从整个视频中播放 3 秒部分

Question

我有一个 10 秒长的视频剪辑，我想从 3 秒播放到 6 秒。CCPlayer可以做到吗？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

这是文档中的两个二传手。

// 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];

:)

更改 MPMoviewPlayer 中的 currentPlaybackRate 时间，

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