BDCamera is a simple video and photo camera with AVFoundation.

Get Started

Installation with CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like AFNetworking in your projects.

Podfile

platform :ios, '7.0'
pod "BDCamera", "~> 0.1"

Default installation

Drag the BDCamera folder to your project. This library must be ARC enabled.

Usage

At first import class for photo

#import "BDStillImageCamera.h"

or video

#import "BDCamera.h"

Make property for your camera

@property (nonatomic, strong) BDStillImageCamera *camera;
// or
@property (nonatomic, strong) BDCamera *camera;

Next, all you need is a UIView container in your controller for camera preview layer.

UIView *cameraView = [[UIView alloc] initWithFrame:self.view.bounds];
self.camera = [[BDStillImageCamera alloc] initWithPreviewView:self preset:AVCaptureSessionPresetPhoto];
//or
self.camera = [[BDCamera alloc] initWithPreviewView:self preset:AVCaptureSessionPreset1280x720];

[self.camera startCameraCapture];

[self.view addSubview:cameraView];

Photo Camera

Make a photo

[self.camera captureImageWithCompletion:^(UIImage *capturedImage, NSError *error) {
        // your captured image
}];

Video Camera

Video Camera has a delegate that gives you url for your recorded video. You need to set a videoDelegate for camera.

  self.camera.videoDelegate = self;

Start record video

NSURL *movieURL = //url for video output file
self.camera startRecordingWithURL:movieURL];

Stop recording

[self.camera stopRecording];

Video output will we sended in videoDelegate

- (void)didFinishRecordingToOutputFileAtURL:(NSURL *)outputFileURL error:(NSError *)error
{
    // here you can save your recorded video to Photos, for example.
    ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init];
    [assetLibrary writeVideoAtPathToSavedPhotosAlbum:outputFileURL completionBlock:^(NSURL *assetURL, NSError *error) {
        [[NSFileManager defaultManager] removeItemAtURL:url error:nil];
        [self showSuccessAlert];
    }];
}

Examples of using BDCamera included in example project.

Some useful things

Change recording FPS

You can recording slow motion videos with switching output FPS. Max FPS for iPhone 5 - 60. Max FPS for iPhone 5S - 120. iPhone 5S: BDCamera recording video with AVCaptureMovieFileOutput and you can control your slow-motion videos in Photos.

[self.camera switchFPS:120.f];

Live previews feed

BDCamera has a functionality of live previews.

/*
    Every item in this array should be BDLivePreview for render live preview
 */
@property (nonatomic, strong) NSMutableArray *displayedPreviews;

BDLivePreview is a subclass of GLKView. You can create BDLivePreview with videoCamera EAGLContext.

//You need to enable sample buffer capturing
[self.camera captureSampleBuffer:YES];

// then create preview views
CGRect frame = //some frame
BDLivePreview *preview = [[BDLivePreview alloc] initWithFrame:frame context:self.camera.eaglContext];
self.camera.displayedPreviews addObject:preview];
[self.view addSubview:preview];

That's all. I have tested BDCamera on 9 live previews.
