Currently, hasAvailableFrameCallback is called whenever we render a frame on screen with no exception. This callback is used for two purposes: 1- Let the MediaPlayerPrivate knows that the first frame has been decoded and rendered 2- When gathering frame metadata due to a call to requestVideoFrameCallback 1- is only required once after a flush 2- is only required if the JS has used requestVideoFrameCallback API. We could optimise the code to only call hasAvailableFrameCallback when needed only.
