iOS: How to save a video in your directory and play it afterwards?

Question

I am working in an iOS project. I want may application to download a video from the internet programmatically. Then I want to play it.

Answer 1

I found the answer

here I saved the video

    NSString *stringURL = @"http://videoURL";
NSURL  *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
NSString  *documentsDirectory ;
if ( urlData )
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
   documentsDirectory = [paths objectAtIndex:0];

    NSString  *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"videoName.mp4"];
    [urlData writeToFile:filePath atomically:YES];

}

and this code is for playing the video form its directory

    NSString  *filepath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"videoName.mp4"];

//video URL
NSURL    *fileURL    =   [NSURL fileURLWithPath:filepath];
moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[moviePlayerController play];

Answer 2

If you have a valid url of the video, Apple provides an API to directly buffer videos with NSURL.

1. You should hold a reference to the MPMoviePlayerController object from the controller so that ARC doesn't release the object.

   @property (nonatomic,strong) MPMoviePlayerController* mc; 
   

2. Make the URL

   NSURL *url = [NSURL URLWithString:@"http://www.example.com/video.mp4"];
   

3. Init MPMoviePlayerController with that URL

   MPMoviePlayerController *controller = [[MPMoviePlayerController alloc] initWithContentURL:url];
   

4. Resize the controller, add it to your view, play it and enjoy the video.

   self.mc = controller; // so that ARC doesn't release the controller
   controller.view.frame = self.view.bounds;
   [self.view addSubview:controller.view];
   [controller play]; //Start playing
