Question

我试图找出有关此问题的信息，但没有找到确切的解决方案。

 NSString *strPath = @"video.mp4";
 NSURL *URL = [NSURL fileURLWithPath:strPath];
 AVURLAsset *avAsset = [AVURLAsset URLAssetWithURL:URL options:nil];
 AVAssetExportSession *exportSession = [[AVAssetExportSession alloc]initWithAsset:avAsset presetName:AVAssetExportPresetMediumQuality];
 exportSession.shouldOptimizeForNetworkUse = YES;
 NSString *cachesFolder = [NSTemporaryDirectory() stringByAppendingPathComponent: [NSString stringWithFormat:@"%@", [strPath lastPathComponent]]];
 NSURL *fileUrl = [NSURL fileURLWithPath:cachesFolder];
 exportSession.outputURL = fileUrl;
 exportSession.outputFileType = AVFileTypeMPEG4;

 exportSession exportAsynchronouslyWithCompletionHandler:^{
     switch ([exportSession status]) {
        case AVAssetExportSessionStatusFailed:
           NSLog(@"Export failed");
         break;
        case AVAssetExportSessionStatusCompleted:
           NSLog(@"Export Completed");
         break;
       default:
         break;
 }

Log: Export failed

我无法评论：（

我只是测试您的代码，一切正常。只需检查调试“ strPath”是否正确（捆绑中包含导出mov文件）

视频导出失败显示错误AVAssetExportSessionStatusFailed
