This is a demo for using OpenGL to render video to a TextureView.
With this you can use OpenGL shaders for video effects during playback.
Important files:
TextureSurfaceRenderer.java - Similar to GLSurfaceView, it initialiazes OpenGL context on a TextureView surface and has an abstract draw() function where OpenGL drawing should be done.
VideoTextureRendrer.java - Extension of TextureSurfaceRendrer that uses OpenGL shaders to render video with OpenGL.
