Green Screen Show while playing video on Webview on Some Android TV

I have an issue to load an video on Webview which is show green screen

I used CustomView also like that

@Override
public void onShowCustomView(View view, WebChromeClient.CustomViewCallback callback) 
{

    Log.e("@@@view",""+"Voirwe");

    if (view == null) {
        return;
    }
    Log.e("@@@view1",""+"customView");
    if (customView != null && callback != null) {
        callback.onCustomViewHidden();
        return;
    }

    customView = view;
    fullscreenHolder = new FrameLayout(context);
    fullscreenHolder.addView(
            customView,
            new FrameLayout.LayoutParams(
                    FrameLayout.LayoutParams.MATCH_PARENT,
                    FrameLayout.LayoutParams.MATCH_PARENT
            ));

    FrameLayout decorView = (FrameLayout) getWindow().getDecorView();
    decorView.addView(
            fullscreenHolder,
            new FrameLayout.LayoutParams(
                    FrameLayout.LayoutParams.MATCH_PARENT,
                    FrameLayout.LayoutParams.MATCH_PARENT
            ));

    customView.setKeepScreenOn(true);
    ((View) currentAlbumController).setVisibility(View.GONE);
    setCustomFullscreen(true);

    if (view instanceof FrameLayout) {
        if (((FrameLayout) view).getFocusedChild() instanceof VideoView) {
            videoView = (VideoView) ((FrameLayout) view).getFocusedChild();
            videoView.setOnErrorListener(new VideoCompletionListener());
            videoView.setOnCompletionListener(new VideoCompletionListener());
        }
    }
    fullscreenHolder.bringToFront();
}

@Override
public void onHideCustomView() {
    Log.e("@@@view","hide");
    FrameLayout decorView = (FrameLayout) getWindow().getDecorView();
    decorView.removeView(fullscreenHolder);

    customView.setKeepScreenOn(false);
    ((View) currentAlbumController).setVisibility(View.VISIBLE);
    setCustomFullscreen(false);

    fullscreenHolder = null;
    customView = null;
    if (videoView != null) {
        videoView.setOnErrorListener(null);
        videoView.setOnCompletionListener(null);
        videoView = null;
    }
    contentFrame.requestFocus();
}
