如何从资产库中播放视频文件

Question

如何从资产库中播放视频文件？我有像文件的URL

"assets-library://asset/asset.MOV?id=1000000023&ext=MOV"

但是我无法使用以下代码在媒体播放器中播放此文件:

NSString *urlAddress = @"assets-library://asset/asset.mov?id=1000000023&ext=mov"; 
NSURL *theURL = [NSURL URLWithString:urlAddress]; 
MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:theURL];

Answer 1

我也遇到了问题,并得到了解决方案.我使用了以下代码,它对我有用.这urlAddress是视频的网址ALAssetsLibrary.

-(void)playVideo:(NSString *)urlAddress{

NSString *newUrl = [[NSString alloc] initWithFormat:@"%@",urlAddress];

NSURL *theURL = [NSURL URLWithString:newUrl];

//player = [[MPMoviePlayerController alloc] init];

[player setContentURL:theURL];
[player prepareToPlay];
[player play]; 

}
