gl_FragColor = vec4(r, g, b, 1.0);

val mediaPlayer = MediaPlayer().apply setDataSource(videoPath) setSurface(Surface(renderer.getSurfaceTexture())) prepare() start()

The renderer’s SurfaceTexture feeds frames to the shader. Add a setting in UI: override fun onSurfaceChanged(gl: GL10

fun getSurfaceTexture(): SurfaceTexture = surfaceTexture

private fun generateTexture(): Int // ... generate GL_TEXTURE_EXTERNAL_OES texture config: EGLConfig?) program = createProgram(vertexShader
