How can I record with filter in Show + Capture Camera?

[thenopen]

I've started android programming. I tried to review your code to CameraCameraActivity.
I don't know how can I record both video and filters to a file.
Please show me your hint.

For drawing on screen, CameraCaptureActivity sets up a GLES program with a filter and renders with it. For recording to video, a separate (but shared) EGL context is used. You'd need to modify TextureViewEncoder to set up and use a filter. An easy way to do that would be to clone CameraCaptureActivity#updateFilter() into TextureViewEncoder, which also uses a FullFrameRect for rendering.

Another approach would be to structure the code more like ContinuousCaptureActivity, which uses a single EGL context for rendering to the screen and to the video output file. CameraCaptureActivity uses separate EGL contexts because there's no real choice with GLSurfaceView.
