Not able to create an AVAsset from the exportSession.outputUrl.

[abhipermukha]

I am trying to export the recorded video and then create an AVAsset from the exportSession.outputUrl so that i can use this asset for mixing other audios to the video as per the requirement of my app. But i am not able to create an AVAsset from the exportSession.outputUrl .

If I save it to camera roll , then i am able to create an AVAsset. But without saving to camera roll, just after the completion of exporting, if i try to create an AVAsset from the exportSession.outputUrl, then it says the duration of the asset is zero seconds(when i print the duration of asset).

Please help me out.

Thanks.

code is as below,

• (void)saveToCameraRoll { self.navigationItem.rightBarButtonItem.enabled = NO; SCFilter *currentFilter = [self.filterSwitcherView.selectedFilter copy]; [_player pause];

  SCAssetExportSession *exportSession = [[SCAssetExportSession alloc] initWithAsset:self.recordSession.assetRepresentingSegments]; exportSession.videoConfiguration.filter = currentFilter; exportSession.videoConfiguration.preset = SCPresetHighestQuality; exportSession.audioConfiguration.preset = SCPresetHighestQuality; exportSession.videoConfiguration.maxFrameRate = 35;

  exportSession.outputUrl = self.recordSession.outputUrl;

  exportSession.outputFileType = AVFileTypeQuickTimeMovie;//AVFileTypeMPEG4; exportSession.delegate = self; exportSession.contextType = SCContextTypeAuto; self.exportSession = exportSession;

  self.exportView.hidden = NO; self.exportView.alpha = 0; CGRect frame = self.progressView.frame; frame.size.width = 0; self.progressView.frame = frame;

  [UIView animateWithDuration:0.3 animations:^{ self.exportView.alpha = 1; }];

  //SCWatermarkOverlayView *overlay = [SCWatermarkOverlayView new]; //overlay.date = self.recordSession.date; //exportSession.videoConfiguration.overlay = overlay; //exportSession.videoConfiguration.watermarkFrame = CGRectMake([UIScreen mainScreen].bounds.size.width-210, [UIScreen mainScreen].bounds.size.height-210, 200, 200);

  //exportSession.videoConfiguration.watermarkFrame = CGRectMake(0, 0, 200, 200); //exportSession.videoConfiguration.watermarkImage = [UIImage imageNamed:@"watermark"]; NSLog(@"Starting exporting");

  CFTimeInterval time = CACurrentMediaTime(); __weak typeof(self) wSelf = self; [exportSession exportAsynchronouslyWithCompletionHandler:^{ __strong typeof(self) strongSelf = wSelf;

    if (!exportSession.cancelled) {
        NSLog(@"Completed compression in %fs", CACurrentMediaTime() - time);
    }
  
    if (strongSelf != nil) {
        [strongSelf.player play];
        strongSelf.exportSession = nil;
        strongSelf.navigationItem.rightBarButtonItem.enabled = YES;
  
        [UIView animateWithDuration:0.3 animations:^{
            strongSelf.exportView.alpha = 0;
        }];
    }
  
    NSError *error = exportSession.error;
    if (exportSession.cancelled) {
        NSLog(@"Export was cancelled");
    } else if (error == nil) {
        [[UIApplication sharedApplication] beginIgnoringInteractionEvents];
        [exportSession.outputUrl saveToCameraRollWithCompletion:^(NSString * _Nullable path, NSError * _Nullable error) {
            [[UIApplication sharedApplication] endIgnoringInteractionEvents];
  
            if (error == nil) {
                [[[UIAlertView alloc] initWithTitle:@"Saved to camera roll" message:@"" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
                NSLog(@"path = %@",path);
  
                NSLog(@"exportSession.outputUrl = %@",[exportSession.outputUrl absoluteString]);
                NSData *videoFile = [NSData dataWithContentsOfURL:exportSession.outputUrl];
                NSLog(@"videoFile size is : %.2f MB",(float)videoFile.length/1024.0f/1024.0f);
  
                AVAsset *asset = [AVAsset assetWithURL:[NSURL fileURLWithPath:[exportSession.outputUrl absoluteString]]];
                float duration = asset.duration.value/asset.duration.timescale;
  
                NSLog(@"duration = %f",duration);  //this gets printed as 0.00 , why????????
  
            } else {
                [[[UIAlertView alloc] initWithTitle:@"Failed to save" message:error.localizedDescription delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
            }
        }];
    } else {
        if (!exportSession.cancelled) {
            [[[UIAlertView alloc] initWithTitle:@"Failed to save" message:error.localizedDescription delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
        }
    }
  

  }]; }
