I am doing my work about capturing screen and encoding on Android 5.0. I want to control the frame rate and read this below

Controlling Frame Rate of VirtualDisplay

I created a SurfaceTexture and a Surface initialised by the SurfaceTexture , and pass the Surface to createVirtualDisplay.

The onFrameAvailable callback fired, almost 60 times per second.

But when I try to save a frame, the data got from glReadPixels is 0

Anyone knows about it? Any help would be greatly appreciated!
