I have already set up a session that can take photos using the AVFoundation and I have a custom camera, so I am not using the default picker controller. How can I add the option to record video?
On the button I have added a gesture that detects if it has been held and this should start the video recording. I'll post the code I have for the image capture first, and then post the code that I have tried to use for the video capture. Sorry in advance for the long post
Photo Capture Code:
(view did load)
session = [[AVCaptureSession alloc]init];
[session setSessionPreset:AVCaptureSessionPresetHigh];
inputDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
NSError * error;
deviceInput = [AVCaptureDeviceInput deviceInputWithDevice:inputDevice error:&error];
if([session canAddInput:deviceInput])
{
[session addInput:deviceInput];
}
previewLayer = [[AVCaptureVideoPreviewLayer alloc] initWithSession:session];
[previewLayer setVideoGravity:AVLayerVideoGravityResizeAspectFill];
CALayer * rootLayer = [myImageView layer];
[rootLayer setMasksToBounds:YES];
CGRect frame = CGRectMake(0,0,400,800);
[previewLayer setFrame:frame];
[rootLayer insertSublayer:previewLayer atIndex:0];
stillImageOutput = [[AVCaptureStillImageOutput alloc] init];
NSDictionary * outputSettings = [[ NSDictionary alloc] initWithObjectsAndKeys:AVVideoCodecJPEG, AVVideoCodecKey, nil];
[stillImageOutput setOutputSettings:outputSettings];
[session addOutput:stillImageOutput];
movieFileOutput = [[AVCaptureMovieFileOutput alloc] init];
[session startRunning];
(button method)
AVCaptureConnection * videoConnection = nil;
for(AVCaptureConnection * connection in stillImageOutput.connections)
{
for(AVCaptureInputPort * port in [connection inputPorts])
{
if([[port mediaType] isEqual:AVMediaTypeVideo])
{
videoConnection = connection;
break;
}
}
if(videoConnection)
{
break;
}
}
[stillImageOutput captureStillImageAsynchronouslyFromConnection:videoConnection completionHandler:^(CMSampleBufferRef imageDataSampleBuffer, NSError *error) {
if(imageDataSampleBuffer != NULL)
{
NSData * imageData = [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageDataSampleBuffer];
UIImage * image2 = [UIImage imageWithData:imageData];
myImageView.image= image2;
previewLayer.hidden = YES;
[self didFinishSelectingPhoto];
}
}];
Video Capture Code (does not work)
- (void)doAction:(UILongPressGestureRecognizer *)recognizer {
if (recognizer.state == UIGestureRecognizerStateBegan) {
//start video
[session beginConfiguration];
AVCaptureDevice *videoCaptureDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
AVCaptureDeviceInput *videoInput = [[AVCaptureDeviceInput alloc] initWithDevice:videoCaptureDevice error:nil];
AVCaptureSession *session = [[AVCaptureSession alloc] init];
[session addInput:videoInput];
[session addOutput:movieFileOutput];
[session commitConfiguration];
[self startRecording];
}
}
- (void)startRecording
{
[movieFileOutput startRecordingToOutputFileURL:[self tempFileURL]
recordingDelegate:self];
}
- (void) stopRecording
{
NSLog(@"stop recording");
[movieFileOutput stopRecording];
}
- (NSURL *) tempFileURL
{
NSString *outputPath = [[NSString alloc] initWithFormat:@"%@%@", NSTemporaryDirectory(), @"output.mov"];
NSURL *outputURL = [[NSURL alloc] initFileURLWithPath:outputPath];
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:outputPath]) {
NSLog(@"file saved");
}
return outputURL;
}
