首先添加AVFoundation和CoreMedia.framework
+(UIImage *)getImage:(NSString *)videoURL{
AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:[NSURL fileURLWithPath:videoURL] options:nil];
AVAssetImageGenerator *gen = [[AVAssetImageGenerator alloc] initWithAsset:asset];
gen.appliesPreferredTrackTransform = YES;
CMTime time = CMTimeMakeWithSeconds(0.0, 600);
NSError *error = nil;
CMTime actualTime;
CGImageRef image = [gen copyCGImageAtTime:time actualTime:&actualTime error:&error];
UIImage *thumb = [[UIImage alloc] initWithCGImage:image];
CGImageRelease(image);
return thumb;
}
另一種方法
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:videoURL];
moviePlayer.shouldAutoplay = NO;
UIImage *thumbnail = [moviePlayer thumbnailImageAtTime:time timeOption:MPMovieTimeOptionNearestKeyFrame];
//這個也一樣
+(UIImage *)fFirstVideoFrame:(NSString *)path {
MPMoviePlayerController *mp = [[MPMoviePlayerController alloc]
initWithContentURL:[NSURL fileURLWithPath:path]];
UIImage *img = [mp thumbnailImageAtTime:0.0
timeOption:MPMovieTimeOptionNearestKeyFrame];
[mp stop];
[mp release];
return img;
}
