Android: apply OpenGL effects to camera

Question

Is there any way in Android to use a GLSurfaceView to display the camera preview, while using OpenGL effects on that surface? Specifically additive blending effects. I know OpenGL can use the effects, and I know the camera can be placed on a SurfaceView, but can a camera be placed in a GLSurfaceView and have OpenGL blending effects applied to that camera preview?

Answer 1

You can use camera preview to get the raw pixels of camera frames, then upload it to a texture, and then you can do any effects you want. Try looking at this: Android Camera OpenGL ES Tutorial (android camera support is quite buggy though, it almost never works when used this way).
