Video Playback on Texture - Black screen appears at beginning for a moment

Issue explanation: a blank screen appears for a few moments (it's usually less than half a second), after the target was detected

When?: right after a target is detected, and the video is right about to start (PLAYING state)

How to solve? Well, the solution is based on NalinS' idea: try to delay a few frames the render of the contents

Just go to VideoPlaybackRenderer.java, inside renderFrame method, and replace this:

if ((currentStatus[currentTarget] == VideoPlayerHelper.MEDIA_STATE.READY)

|| (currentStatus[currentTarget] == VideoPlayerHelper.MEDIA_STATE.REACHED_END)

|| (currentStatus[currentTarget] == VideoPlayerHelper.MEDIA_STATE.NOT_READY)

|| (currentStatus[currentTarget] == VideoPlayerHelper.MEDIA_STATE.ERROR))

{

.....

} else {

.....

}

with this:

if ((currentStatus[currentTarget] == VideoPlayerHelper.MEDIA_STATE.READY)

|| (currentStatus[currentTarget] == VideoPlayerHelper.MEDIA_STATE.REACHED_END)

|| (currentStatus[currentTarget] == VideoPlayerHelper.MEDIA_STATE.NOT_READY)

|| (currentStatus[currentTarget] == VideoPlayerHelper.MEDIA_STATE.ERROR))

{

.....

} else {

mFramesPlayed++;

if (mFramesPlayed < MAX_FRAMES_TO_JUMP) return;

.....

}

You will also have to add a new class member:

private int mFramesPlayed = 0;

And a constant to define how many frames you'd like to eat from the beginning of the video:

private static final int MAX_FRAMES_TO_JUMP = 10;

Hope this helps someone!
