Record, Save And/Or Convert Video in Mp4 Format

Record, save and/or convert video in mp4 format?

You are doing right thing.. Now you need to convert this mov file to mp4 as below.

NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
NSString *videoPath1 = @"";
if (CFStringCompare ((__bridge_retained CFStringRef) mediaType, kUTTypeMovie, 0) == kCFCompareEqualTo)
 {
   if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(moviePath))
   {
         NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
         NSString *moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];
         videoPath1 =[NSString stringWithFormat:@"%@/xyz.mov",docDir];
         NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
         NSData *videoData = [NSData dataWithContentsOfURL:videoURL];
         [videoData writeToFile:videoPath1 atomically:NO];
       //  UISaveVideoAtPathToSavedPhotosAlbum(moviePath, self, nil, nil);
   }
 }

    AVURLAsset *avAsset = [AVURLAsset URLAssetWithURL:[NSURL fileURLWithPath:videoPath1] options:nil];
    NSArray *compatiblePresets = [AVAssetExportSession exportPresetsCompatibleWithAsset:avAsset];

    if ([compatiblePresets containsObject:AVAssetExportPresetLowQuality])
    {
        AVAssetExportSession *exportSession = [[AVAssetExportSession alloc]initWithAsset:avAsset presetName:AVAssetExportPresetPassthrough];
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        videoPath = [NSString stringWithFormat:@"%@/xyz.mp4", [paths objectAtIndex:0]];
        exportSession.outputURL = [NSURL fileURLWithPath:videoPath];
        NSLog(@"videopath of your mp4 file = %@",videoPath);  // PATH OF YOUR .mp4 FILE
        exportSession.outputFileType = AVFileTypeMPEG4;

      //  CMTime start = CMTimeMakeWithSeconds(1.0, 600);
      //  CMTime duration = CMTimeMakeWithSeconds(3.0, 600);           
      //  CMTimeRange range = CMTimeRangeMake(start, duration);            
      //   exportSession.timeRange = range;        
      //  UNCOMMENT ABOVE LINES FOR CROP VIDEO   
        [exportSession exportAsynchronouslyWithCompletionHandler:^{

            switch ([exportSession status]) {

                case AVAssetExportSessionStatusFailed:
                    NSLog(@"Export failed: %@", [[exportSession error] localizedDescription]);

                    break;

                case AVAssetExportSessionStatusCancelled:

                    NSLog(@"Export canceled");

                    break;

                default:

                    break;

            }
             UISaveVideoAtPathToSavedPhotosAlbum(videoPath, self, nil, nil);

AVFoundation record video in MP4 format

I am currently unaware of how to do it in foundation classes, but you can certainly do it using AVAssetWriter look for option outputFileType and shouldOptimizeForNetworkUse.

Swift - How to record video in MP4 format with UIImagePickerController?

Here is some code that you can use to convert the recorded video into MP4:

func encodeVideo(videoURL: NSURL)  {
let avAsset = AVURLAsset(URL: videoURL, options: nil)

var startDate = NSDate()

//Create Export session
exportSession = AVAssetExportSession(asset: avAsset, presetName: AVAssetExportPresetPassthrough)

// exportSession = AVAssetExportSession(asset: composition, presetName: mp4Quality)
//Creating temp path to save the converted video

let documentsDirectory = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]
let myDocumentPath = NSURL(fileURLWithPath: documentsDirectory).URLByAppendingPathComponent("temp.mp4").absoluteString
let url = NSURL(fileURLWithPath: myDocumentPath)

let documentsDirectory2 = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0] as NSURL

let filePath = documentsDirectory2.URLByAppendingPathComponent("rendered-Video.mp4")
deleteFile(filePath)

//Check if the file already exists then remove the previous file
if NSFileManager.defaultManager().fileExistsAtPath(myDocumentPath) {
    do {
        try NSFileManager.defaultManager().removeItemAtPath(myDocumentPath)
    }
    catch let error {
        print(error)
    }
}

 url

exportSession!.outputURL = filePath
exportSession!.outputFileType = AVFileTypeMPEG4
exportSession!.shouldOptimizeForNetworkUse = true
var start = CMTimeMakeWithSeconds(0.0, 0)
var range = CMTimeRangeMake(start, avAsset.duration)
exportSession.timeRange = range

exportSession!.exportAsynchronouslyWithCompletionHandler({() -> Void in
    switch self.exportSession!.status {
    case .Failed:
        print("%@",self.exportSession?.error)
    case .Cancelled:
        print("Export canceled")
    case .Completed:
        //Video conversion finished
        var endDate = NSDate()

        var time = endDate.timeIntervalSinceDate(startDate)
        print(time)
        print("Successful!")
        print(self.exportSession.outputURL)

    default:
        break
    }

})

}

func deleteFile(filePath:NSURL) {
guard NSFileManager.defaultManager().fileExistsAtPath(filePath.path!) else {
    return
}

do {
    try NSFileManager.defaultManager().removeItemAtPath(filePath.path!)
}catch{
    fatalError("Unable to delete file: \(error) : \(__FUNCTION__).")
}
}

How to save a Video recorded from webcam in mp4 format using mediaDevices in HTML

There is nothing wrong with your code. The format is actually not supported by QuickTime player.

If you use VLC or Chrome/Firefox browser to play the file it will work.
