CameraFilter is a Java library typically used in User Interface, Graphics applications. CameraFilter has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can download it from GitHub.

研究 Android 用 OpenGL ES 2.0 处理相机预览和滤镜。. 使用 GLSurfaceView 显示相机画面，用 OpenGL 实现不同滤镜效果。. android-gpuimage 使用 GL_TEXTURE_2D 作为纹理目标。在处理相机预览画面时，需要将每帧的图像颜色由 YUV 转成 RBGA，画面不流畅。. 这里使用 GL_TEXTURE_EXTERNAL_OES 作为纹理目标，绕过了 YUV 转 RBGA 步骤。另外简单处理了一下预览画面的比例。. 使用 grafika 方案（需要Android 4.3)，用 MediaCodec、MediaMuxer 编码生成 MP4。使用 MediaCodec 的 createInputSurface，接收来自 OpenGL 渲染的画面。. 与 android-gpuimage 一样，使用 GL_TEXTURE_2D 作为纹理目标，传入需要处理的图片，然后用滤镜渲染。不过因为纹理目标不同，不能直接套用相机的滤镜，导致每个滤镜分别要写两次…….

There are a few things wrong with your code on top

You are using a AVCaptureVideoPreviewLayer but this is going to transport pixels capture by the camera directly to the screen, skipping your image processing and CIFilter and is not necessary.

Your conformance to AVCaptureVideoDataOutputSampleBufferDelegate is out of date. func captureOutput(captureOutput: AVCaptureOutput!, didOutputSampleBuffer sampleBuffer: CMSampleBuffer!, fromConnection connection: AVCaptureConnection!) is now called func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection)

Because you won't be using AVCaptureVideoPreviewLayer you'll need to ask for permission before you'll be able to start getting pixels from the camera. This is typically done in viewDidAppear(_:) Like:
