Question

我有一个图像选择器，我选择一个电影（可以编辑）。然后我使用;

抓取缩略图

UIImage *tempImage = [moviePlayerThumb thumbnailImageAtTime:1.0 timeOption:MPMovieTimeOptionNearestKeyFrame];

这项工作很好，我可以用另一种方法显示图像没有问题。我还存储了视频数据以便稍后上传;

[mediaDict setValue:[NSData dataWithContentsOfFile:mediaPath] forKey:@"data"];

这也适用于上传文件时服务器没有问题。

我存储的最后一些东西是URL和路径，然而，当我稍后将它们放入播放器中时，我会卡住播放器说“正在加载”（加上spinny东西）;

我认为这是因为编辑后的选择器将视频存储在临时目录中（当我稍后播放该文件时）已被清空。

路径是这样的;

file://localhost/private/var/mobile/Applications/B26A085A-C471-4972-9070-5A3F8DC48449/tmp//trim.ttCbAg.MOV

我试图让选择器像这样永久存储视频;

    NSString *mediaPath = [[info objectForKey:UIImagePickerControllerMediaURL] path];

    NSURL *mediaURL=[info objectForKey:UIImagePickerControllerMediaURL];
    if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (mediaPath))
    {
        UISaveVideoAtPathToSavedPhotosAlbum (mediaPath, nil, nil, nil);
    }

我知道这是有效的，因为我的相册正在慢慢填满我的视频的编辑版本。问题是如何在UISaveVideo方法之后找出文件的路径？

玩家记录此内容;

[MPAVController] Autoplay: Disabling autoplay for pause
[MPAVController] Autoplay: Disabling autoplay
[MPAVController] Autoplay: Disabling autoplay for pause
[MPAVController] Autoplay: Disabling autoplay
[MPAVController] Autoplay: Skipping autoplay, disabled (for current item: 1, on player: 0)
[MPAVController] Autoplay: Enabling autoplay

播放器代码如下所示（我尝试过使用mediaPath和mediaURL）;

    // Play the movie
    NSURL *tempMediaPath = [NSURL fileURLWithPath:images[indexPath.item][@"path"]];

    NSURL *tempMediaURL = images[indexPath.item][@"URL"];

    NSLog(@"Media Path, URL : %@, %@", tempMediaPath, tempMediaURL);

    MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:tempMediaPath];

    [self.view addSubview:moviePlayer.view];
    [moviePlayer setFullscreen:YES animated:YES];
    [moviePlayer prepareToPlay];
    [moviePlayer play];

和NSLog;

Media Path, URL : file://localhost/private/var/mobile/Applications/B26A085A-C471-4972-9070-5A3F8DC48449/tmp//trim.ttCbAg.MOV, file://localhost/private/var/mobile/Applications/B26A085A-C471-4972-9070-5A3F8DC48449/tmp//trim.ttCbAg.MOV

任何帮助都非常感激。

您可以更好地将文件移动到您控制的临时文件位置：

NSString *tempFileName = [[NSUUID UUID] UUIDString];
NSURL *location = [[NSURL fileURLWithPath:NSTemporaryDirectory()] URLByAppendingPathComponent:tempFileName];

[[NSFileManager new] moveItemAtURL:tempMovieURL toURL:location error:nil];

我在另一个项目中做了同样的事情，以下代码在嵌入模式和全屏模式下都有效：

_movieController = [[MPMoviePlayerController alloc] initWithContentURL:self.movieURL];
_movieController.view.frame = self.view.bounds;
_movieController.controlStyle = MPMovieControlStyleEmbedded;
_movieController.backgroundView.hidden = YES;
_movieController.contentURL = self.movieURL;
[_movieController prepareToPlay];
_movieController.scalingMode = MPMovieScalingModeAspectFit;
_movieController.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
_movieController.shouldAutoplay=YES;
_movieController.movieSourceType = MPMovieSourceTypeFile;
[self.view addSubview:_movieController.view];

在UIImagePicker和UISaveVideoAtPathToSavedPhotosAlbum之后找到mediaPath
