AndroidUSBCamera 2.0
OkCamera
============
============
AndroidUSBCamera is developed based on the saki4510t/UVCCamera, the project of USB Camera (UVC equipment) and the use of video data acquisition are highly packaged, and it can help developers using USB Camera devices easily by a few simple APIs. By using AndroidUSBCamera,you can detect and connect to a USB Camera simply.And you also can use it to realize taking picture,recording mp4,switching resolutions and setting camera's contrast or brightness,etc.Here is some gifs of this demo:

(2) Capturing JPG Images
```java
mCameraHelper.capturePicture(picPath, new AbstractUVCCameraHandler.OnCaptureListener() {
@Override
public void onCaptureResult(String path) {
Log.i(TAG,"save path:" + path);
}
});
```
(3) Recording Mp4,supporting close voice and save file automatic.
```java
RecordParams params = new RecordParams();
params.setRecordPath(videoPath);
params.setRecordDuration(0); // 0,do not cut save
params.setVoiceClose(mSwitchVoice.isChecked()); // is close voice
mCameraHelper.startRecording(params, new AbstractUVCCameraHandler.OnEncodeResultListener() {
@Override
public void onEncodeResult(byte[] data, int offset, int length, long timestamp, int type) {
// type = 1,h264 video stream
if (type == 1) {
// FileUtils.putFileStream(data, offset, length);
}
// type = 0,aac audio stream
if(type == 0) {
}
}
@Override
public void onRecordResult(String videoPath) {
Log.i(TAG,"videoPath = "+videoPath);
}
});
```
(4) setting camera's brightness and contrast.
```java
mCameraHelper.setModelValue(UVCCameraHelper.MODE_BRIGHTNESS,progress);
mCameraHelper.setModelValue(UVCCameraHelper.MODE_CONTRAST,progress);
mCameraHelper.getModelValue(UVCCameraHelper.MODE_BRIGHTNESS);
mCameraHelper.getModelValue(UVCCameraHelper.MODE_CONTRAST);
...
```
(5) switch resolutions and camera.
```java
mCameraHelper.updateResolution(widht, height);
```
At last,remember adding permissions:
```
< uses-permission android:name = "android.permission.WRITE_EXTERNAL_STORAGE" / >
< uses-permission android:name = "android.permission.RECORD_AUDIO" / >
