How can i record video
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.allowsEditing = YES;
imagePickerController.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie];
imagePickerController.delegate = self;
[self presentModalViewController:imagePickerController animated:YES];
[imagePickerController release];
i tried this one but i am getting image capture and i am not getting video capture.
#import <MobileCoreServices/UTCoreTypes.h>
-(void)actionStartVideoRecord:(id)sender {
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
return;
}
UIImagePickerController* imagePicker = [[[UIImagePickerController alloc] init] autorelease];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.videoQuality = UIImagePickerControllerQualityTypeHigh;
imagePicker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie];
imagePicker.delegate = self;
[self presentModalViewController:imagePicker animated:YES];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mType = [info valueForKey:UIImagePickerControllerMediaType];
if([mType isEqualToString:#"public.movie"]){
[NSData dataWithContentsOfURL:[info objectForKey:#"UIImagePickerControllerMediaURL"]]
}
}
Once the imagePickerController is presented, start the videoCapture of the device.
For more info, see doc for UIImagePickerController
You can make a subclass of UIImagePickerController. There you can have a UIButton. On tapping that, you could start capturing the video.

I've got most of this working but I'm stuck with something that might be simple. Im trying to play a video from the camera roll in SpriteKit. A video will play from the main bundle, and the video picker also works until I choose the video. I think I'm locking the main thread because when choosing the video the picker freezes. You're help is extremely appreciated.
.h
#import <SpriteKit/SpriteKit.h>
#import "GameViewController.h"
#import <MobileCoreServices/UTCoreTypes.h>
#interface GameScene : SKScene<UINavigationControllerDelegate,UIImagePickerControllerDelegate>
#end
.m
#import "GameScene.h"
#import <AVFoundation/AVFoundation.h>
#implementation GameScene {
AVPlayer *player;
SKVideoNode *videoNode1;
NSURL *fileURL;
NSString *moviePath;
UIViewController *viewController;
}
-(void)didMoveToView:(SKView *)view {
player = [AVPlayer playerWithURL: fileURL];
videoNode1 = [[SKVideoNode alloc] initWithAVPlayer:player];
videoNode1.size = CGSizeMake(self.frame.size.width,self.frame.size.height);
videoNode1.position = CGPointMake(self.frame.size.width/2.0f,self.frame.size.height/2.0f);
videoNode1.zPosition = 100.0f;
[self addChild:videoNode1];
player.volume = 1.0f;
[videoNode1 play];
}
- (void)getVideo {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
viewController = self.view.window.rootViewController;
[viewController presentViewController: imagePicker animated: YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
if (CFStringCompare ((__bridge CFStringRef) mediaType, kUTTypeMovie, 0) == kCFCompareEqualTo) {
fileURL = (NSURL*)[info objectForKey:UIImagePickerControllerMediaURL];
moviePath = [fileURL path];
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
UISaveVideoAtPathToSavedPhotosAlbum (moviePath, nil, nil, nil);

Answering my own question for others who want this feature. You must set up your node and player in the imagePicker method.
- (void)getVideo {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
viewController = self.view.window.rootViewController;
[viewController presentViewController: imagePicker animated: YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
fileURL = [info objectForKey:UIImagePickerControllerMediaURL];
[picker dismissViewControllerAnimated:YES completion:NULL];
player = [AVPlayer playerWithURL: fileURL];
videoNode1 = [[SKVideoNode alloc] initWithAVPlayer:player];
videoNode1.size = CGSizeMake(self.frame.size.width, self.frame.size.height);
videoNode1.position = CGPointMake(self.frame.size.width/2.0f, self.frame.size.height/2);
videoNode1.zPosition = 100.0f;
[self addChild:videoNode1];
player.volume = 1.0f;
[videoNode1 play];
}
I am accessing default camera in my app.Sometimes it is displaying black screen.What is the solution for this problem?.
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera])
{
imgPicker = [[UIImagePickerController alloc] init];
imgPicker.delegate = self;
imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
// imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil];
imgPicker.allowsEditing = NO;
imgPicker.showsCameraControls = NO;
cameraView.backgroundColor = [UIColor clearColor];
imgPicker.cameraOverlayView = cameraView;
[self presentModalViewController:imgPicker animated:YES];
}
I think the issue is with the way you present the UIImagePickerController instance:
UIImagePickerController * imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
[self presentModalViewController:imagePicker animated:YES];
// [picker release];
I am using ImagePickerController for Video Capturing. I need to save the capturing video as image also.
So I selected AVCaptureSession for capturing Images. I'm not able to run AVCaptureSession as well as ImagePickerController. So I need to give the ImagePickerController as input to the AVCaptureSession.
But I don't know how to do that. Please Help me.. and suggest me for the right way.
I found only these two. Hope its helps.

UIImagePickerController: Getting image capture from video
I was having same issue.. I did work on image and video and used below code for image capturing:
- (void) snapImage: (id) sendern
{
UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.sourceType = UIImagePickerControllerSourceTypeCamera;
ipc.delegate = self;
ipc.allowsImageEditing = YES;
[self presentModalViewController:ipc animated:YES];
}
And for video recording i used below code:
- (void) recordVideo: (id) sender
{
UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.sourceType = UIImagePickerControllerSourceTypeCamera;
ipc.delegate = self;
ipc.allowsEditing = YES;
ipc.videoQuality = UIImagePickerControllerQualityTypeMedium;
ipc.videoMaximumDuration = 30.0f; // 30 seconds
ipc.mediaTypes = [NSArray arrayWithObject:#"public.movie"];
// ipc.mediaTypes = [NSArray arrayWithObjects:#"public.movie", #"public.image", nil];
[self presentModalViewController:ipc animated:YES];
}
Hope will help you both code snippets.
- (IBAction) useCamera: (id)sender
{
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController *imagePicker =
[[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType =
UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObjects:
(NSString *) kUTTypeImage,
nil];
imagePicker.allowsEditing = NO;
[self presentModalViewController:imagePicker
animated:YES];
newMedia = YES;
}
}
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self.popoverController dismissPopoverAnimated:true];
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
[self dismissModalViewControllerAnimated:YES];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage])
{
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
imageView.image = image;
if (newMedia)
UIImageWriteToSavedPhotosAlbum(image, self,
#selector(image:finishedSavingWithError:contextInfo:),nil);
}
}
-(void)image:(UIImage *)image
finishedSavingWithError:(NSError *)error
contextInfo:(void *)contextInfo
{
if (error)
{
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle: #"Save failed"
message: #"Failed to save image"
delegate: self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
}
The Apple docs and sample code related to AVFoundation has several mistakes. See iOS 4: Take photos with live preview using AVFoundation for code that actually captures images from a live preview.
I hope to load the videos in ipod/iphone library like app 'videos'.
the codes show below, but it always cause crash
UIImagePickerController *picker=[[UIImagePickerController alloc]init];
picker.sourceType= UIImagePickerControllerSourceTypePhotoLibrary;
picker.mediaTypes = [NSArray arrayWithObject:kUTTypeMovie];
picker.delegate = self;
Welcome any comment
Thanks

We need to know how you are presenting it as well and perhaps information about the line it crashed on if it happens to be in your code. Here is an example that works for me:
- (void)presentVideoPicker:(UIImagePickerControllerSourceType)sourceType
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = [self retain];
picker.mediaTypes = [NSArray arrayWithObjects:(NSString*)kUTTypeMovie, kUTTypeImage, nil];
picker.videoQuality = UIImagePickerControllerQualityTypeHigh;
picker.allowsEditing = YES;
picker.sourceType = sourceType;
[self.view.window.rootViewController presentModalViewController:picker animated:YES];
[picker release];
}
I send it UIImagePickerControllerSourceTypeCamera or UIImagePickerControllerSourceTypePhotoLibrary
I 'm new to xcode. I try to select an image from the UIImagePickerController and
then display this image pressing a button. But the simulator crashes.
In the .h I use
UIImage *dispimage; //in order to make a global image
-(IBAction) open;
-(IBAction) print;
In the .m I have
- (void)viewDidLoad {
self.imgPicker = [[UIImagePickerController alloc] init];
self.imgPicker.allowsImageEditing = YES;
self.imgPicker.delegate = self;
self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
dispimage = [info objectForKey:UIImagePickerControllerOriginalImage];
[self dismissModalViewControllerAnimated:YES];
}
-(IBAction) open{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];
};
-(IBAction) print{
imageView.image=dispimage;
};
When the button "print" is pressed, the sdk crashes. :(
Any help would be appreciated
Thanks in advance
Here is the code to get images from UIImagePickerController
-(void)viewDidLoad
{
self.imgPicker = [[UIImagePickerController alloc] init];
self.imgPicker.allowsImageEditing = YES;
self.imgPicker.delegate = self;
self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
dispimage = [[info objectForKey:UIImagePickerControllerOriginalImage]retain];
[picker dismissModalViewControllerAnimated:YES];
}
-(IBAction)open
{
if(self.imgPicker == nil)
{
self.imgPicker = [[UIImagePickerController alloc] init];
self.imgPicker.allowsImageEditing = YES;
self.imgPicker.delegate = self;
self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
[self presentModalViewController:self.imagePicker animated:YES];
[self.imagePicker release];
}
-(IBAction) print
{
if(dispimage != nil)
{
imageView.image=dispimage;
}
};
