Video Recording with Camera2 and apply video filter.

Step 1. Add the JitPack repository to your build file

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Step 2. Add the dependency

dependencies {
     implementation 'com.github.MasayukiSuda:CameraRecorder-android:v0.1.5'
}

Usage

SetUp on onResume method.

  sampleGLView = new GLSurfaceView(getApplicationContext());
  FrameLayout frameLayout = findViewById(R.id.wrap_view);
  frameLayout.addView(sampleGLView);

  cameraRecorder = new CameraRecorderBuilder(activity, sampleGLView)
    .lensFacing(LensFacing.BACK)
    .build();

Release on onPause method.

  sampleGLView.onPause();      

  cameraRecorder.stop();
  cameraRecorder.release();
  cameraRecorder = null;

  ((FrameLayout) findViewById(R.id.wrap_view)).removeView(sampleGLView);
  sampleGLView = null;

Start and Stop Video record.

  // record start.
  cameraRecorder.start(filepath);
  // record stop.
  cameraRecorder.stop();

This filter is OpenGL Shaders to apply effects on camera preview. Custom filters can be created by inheriting GlFilter.java. , default GlFilter(No filter). Filters is here.

  cameraRecorder.setFilter(GlFilter);

Other methods.

  // if flash enable, turn on or off camera flash. 
  cameraRecorder.switchFlashMode();
  // autofocus change.
  cameraRecorder.changeAutoFocus();
  // set focus point at manual.
  cameraRecorder.changeManualFocusPoint(float eventX, float eventY, int viewWidth, int viewHeight); 
  // scale camera preview
  cameraRecorder.setGestureScale(float scale);
