How to play video from NSData - mpmovieplayercontroller

Question

I would like to know if it's possible to play a video from an NSData object... with the MPMoviePlayerController.

Answer 1

Ben's answer works perfectly on simulator but wont work on the device, You cannot write anywhere on the device. Check code below
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"myMove.mp4"];
[videoData writeToFile:path atomically:YES];
NSURL *moveUrl = [NSURL fileURLWithPath:path];
player = [[MPMoviePlayerController alloc]init];
[player setContentURL:moveUrl];
player.view.frame = viewPlayer.bounds;
[viewPlayer addSubview:player.view];
[player play];

Answer 2

As far as I know this is not possible. If the data comes from your DB, can you save it into a temporary file and play that?

Answer 3

It is better to use NSFileManager in this case instead writeToFile
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"myMove.mp4"];
[[NSFileManager defaultManager] createFileAtPath:path contents:videoData attributes:nil];
NSURL *moveUrl = [NSURL fileURLWithPath:path];
player = [[MPMoviePlayerController alloc]init];
[player setContentURL:moveUrl];
player.view.frame = viewPlayer.bounds;
[viewPlayer addSubview:player.view];
[player play];

create a file with the type of your NSData for example if your NSData is type of mp4 create a file with that type - for example - "myMove.mp4"
copy past the file to your app resurces
add this code
NSData *mediaData; //your data
NSString *movePath=[[NSBundle mainBundle] pathForResource:#"myMove" ofType:#"mp4"];
[mediaData writeToFile:movePath atomically:YES];
NSURL *moveUrl= [NSURL fileURLWithPath:movePath];
MPMoviePlayerController *movePlayer=[[MPMoviePlayerController alloc]init];
[movePlayer setContentURL:moveUrl];
[movePlayer play];
