-// An overlay validator for supporting fullscreen video underlays on Android.
-// Things are a bit different on Android compared with other platforms. By the
-// time a video frame is marked as overlayable it means the video decoder was
-// outputting to a Surface that we can't read back from. As a result, the
-// overlay must always succeed, or the video won't be visible. This is one of of
-// the reasons that only fullscreen is supported: we have to be sure that
-// nothing will cause the overlay to be rejected, because there's no fallback to
-// gl compositing.
