Try this :
.h file
import MediaPlayer/MediaPlayer.h
NSString *strSelectedVideoPath;
MPMoviePlayerController *player
#property (nonatomic,retain) NSString *strSelectedVideoPath;
#property (nonatomic,retain) MPMoviePlayerController *player;
.m file
-(void) viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:strSelectedVideoPath]];
player.scalingMode = MPMovieScalingModeFill;
player.movieSourceType = MPMovieSourceTypeFile;
player.view.frame = CGRectMake(0, 45, 320, 400);
player.shouldAutoplay = YES;
[player prepareToPlay];
[self.view addSubview:player.view];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(movieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification object:player];
[player play];
}
- (void) movieFinishedCallback:(NSNotification*) aNotification {
MPMoviePlayerController *player1 = [aNotification object];
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:player1];
[player1.view removeFromSuperview];
player1 = nil;
}
You have to add MediaPlayer.framework
For Record video :
-(void) imagePickerController: (UIImagePickerController *) picker didFinishPickingMediaWithInfo: (NSDictionary *) info {
NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
[self dismissModalViewControllerAnimated:NO];
if (CFStringCompare ((CFStringRef) mediaType, kUTTypeMovie, 0)
== kCFCompareEqualTo) {
NSString *moviePath = [[info objectForKey: UIImagePickerControllerMediaURL] path];
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
UISaveVideoAtPathToSavedPhotosAlbum (moviePath,self,#selector(video:didFinishSavingWithError:contextInfo:), nil);
}
}
}
- (void)video:(NSString*)videoPath didFinishSavingWithError:(NSError*)error contextInfo:(void*)contextInfo {
if (error) {
}
else{
NSURL *videoURl = [NSURL fileURLWithPath:videoPath];
AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:videoURl options:nil];
AVAssetImageGenerator *generate = [[AVAssetImageGenerator alloc] initWithAsset:asset];
generate.appliesPreferredTrackTransform = YES;
NSError *err = NULL;
//For Thumb Image
CMTime time = CMTimeMake(1, 60);
CGImageRef imgRef = [generate copyCGImageAtTime:time actualTime:NULL error:&err];
self.strUploadVideoPath = videoPath;
CGImageRelease(imgRef);
[generate release];
[asset release];
}
}
