Android OpenGL video renderer based on GPUImage, providing color blind correction filters.

1. init GLSurfaceView

 mPlayerView = new GLSurfaceView(this);
 mPlayerView.getHolder().addCallback(this);
 mPlayerView.setEGLContextFactory(new ContextFactory());
 mPlayerView.setEGLConfigChooser(new ConfigChooser());
 
 spoRenderer = new SpoRenderer(mPlayerView);
 mPlayerView.setRenderer(spoRenderer);

2. init player

 player = new MediaPlayer();
 player.setDataSource(url);
 player.prepare();
 spoRenderer.setPlayer(player);
 mPlayerView.onResume();

3. set filter or filter intensity

spoRenderer.setGlFilter(new GlFilter());

or

spoRenderer.setGlFilter(new GlRedBlindFilter(5))

or

spoRenderer.setGlFilterIntensity(8)

4. release

   @Override
public void surfaceDestroyed(SurfaceHolder holder) {
   ...
   spoRenderer.release();
　...
}

Protanope and Protanomaly Correction

spoRenderer.setGlFilter(new GlRedBlindFilter(intensity));

Deuteranopia and Deuteranomaly Correction

spoRenderer.setGlFilter(new GlGreenBlindFilter(intensity));

Tritanopia and Tritanomaly Correction

spoRenderer.setGlFilter(new GlBlueBlindFilter(intensity));
