Simple OpenGL Shaders with the camera2 apis in Android 5.0+
Check out shadercam-example here for basic usage.
Also, shadercam was built for usage with a couple Android Experiments:
updated 9/14/15
We've added a PermissionsHelper
fragment to make handling Android M's new permissions model a bit easier.
Refer to the example applications MainActivity.java
for implementation specifics.
Import shadercam in your build.gradle file:
compile project(':shadercam')
or
compile 'com.androidexperiments:shadercam:1.1.0'
shadercam comes with a simple implementation of the camera2 apis called CameraFragment, which only
requires that you add a TextureView to your layout.
private void setCameraFragment() {
mCameraFragment = CameraFragment.getInstance();
mCameraFragment.setCameraToUse(CameraFragment.CAMERA_PRIMARY); //or CAMERA_BACK
mCameraFragment.setTextureView(mTextureView); //the TextureView we added to our layout
//add fragment to our setup and let it work its magic
getSupportFragmentManager().beginTransaction()
.add(mCameraFragment, TAG_CAMERA_FRAGMENT) //any tag is fine if u want to access later
.commit();
}
Once your CameraFragment is setup, we need to wait until our TextureView is ready to create
our CameraRenderer.
public void onResume() {
if(!mTextureView.isAvailable())
mTextureView.setSurfaceTextureListener(mTextureListener);
else
setReady(mTextureView.getSurfaceTexture(), mTextureView.getWidth(), mTextureView.getHeight());
}
Our texture listener is your normal, every day TextureView.SurfaceTextureListener that will also call our setReady method that will create our renderer.
Now all you have to do is extend CameraRenderer to do anything you want with the video feed!
private void setReady(SurfaceTexture surface, int width, int height) {
mRenderer = new ExampleRenderer(this, surface, mCameraFragment, width, height);
mRenderer.setOnRendererReadyListener(this);
mRenderer.start();
//initial config if needed
mCameraFragment.configureTransform(width, height);
}
Check out MainActivity and ExampleRenderer in shadercam-example for more in depth explanations and details.
If you make something cool with shadercam, let us know by heading over to Android Experiments and submitting your experiment!
