CameraPreviewController

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

I'm writing this since I couldn't find a open source with complete basic source to start develop camera application from, and is based on GPUImage library inside.

This example contains the following features.

1. front camera preview / still capture / video capture

2. back camera preview / still capture / video capture

3. flipping camera

4. torch control

5. tap to focus

6. add/remove filter

7. face detection

8. pinch to zoom in/out

I'm going to add more features that every camera application must have.

Please don't hesitate to contribute on this project. Any advice and suggestions will be greatly appreciated.
