以2x 3x 4x速度播放/转发视频 - iPhone SDK [英] Play/Forward video in 2x 3x 4x speed - iPhone SDK

问题描述

我想以不同的速度在MPMoviePlayerController中播放/转发视频。任何人都可以建议我如何做到这一点。

I want to play/forward video in MPMoviePlayerController with different speeds. Can any one suggest me how i do this.

现在我正在快进（单速），但在几秒钟后它恢复正常速度。

Right now i am doing fast forward (On single speed) but in few seconds it come back on normal speed.

请建议。

推荐答案

MPMoviePlayerController Conforms to MPMediaPlayback protocol 
you can see the property currentPlaybackRate as :-
@property(nonatomic) float currentPlaybackRate 
A value of 0 represents that the video is stopped , a value of 1 indicates normal speed and further positive values indicate increased speed while negative ones indicate reverse .

同时检查你的MPMediaPlayback的endseeking委托方法，因为它是将播放恢复正常的唯一方法

Also check your endseeking delegate method of MPMediaPlayback as it is the only method that reverts the playback to normal
