Timestamp of each frame
See original GitHub issueIs calling cameraTexture.getTimestamp() after cameraTexture.updateTexImage() the closest time in nanoseconds we can get to when the camera sensor exposed first row of image sensor?
I see a comment by @fadden on this SO post that says you can get the timestamp from the camera if you send the frames to a SurfaceTexture, and do your work in GLES instead of Java. Is the timestamp from SurfaceTexture the time when frame was captured, or received by the SurfaceTexture? Is the time between these two significantly low (<1ms) to be ignorable?

@CreaRo I’ve had the same problem in trying to sync the timestamps from the camera and the microphone. It’s still unclear to me how that’s supposed to work.
@CreaRo if you post on SO, can you link to it here?
