Does hardware acceleration effect in any way VideoView when
displaying a video ?
Thinking back and seeing that onCreate reports hardwareAcceleration as
false, because this is too early
and in fact it is true when checked after onCreate.
perhaps all along I have had hardware acceleration, so then the question
should have been does h/w acc. effect VideoView
and this is why I can hear but not see the video ?
Thanks

LayoutInflater inflater = (LayoutInflater)
getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.image_viewer, screen);
FrameLayout parent = (FrameLayout)
view.findViewById(R.id.image);
Log.e("main", "view is " + view.isHardwareAccelerated() );
Media image = null;
Log.e("main", "parent is " + parent.isHardwareAccelerated() );
image = new Media_Video (getApplicationContext() , parent
, fName);
Log.e("main", "=============================================");
Log.e("main", "view is " + view.isHardwareAccelerated() );
Log.e("main", "parent is " + parent.isHardwareAccelerated() );
Log.e("main", "image is " + image.isHardwareAccelerated() );
Log.e("main", "screen is " + screen.isHardwareAccelerated() );
Log.e("main", "=============================================");
image.ButtonSetup(view);
screen.setOnTouchListener(image);
Where Media_Video has the following
video = (VideoView) screen.findViewById(R.id.video);
video.setKeepScreenOn(true);
video.setClickable(true);
video.setVideoPath(fName);
Log.i("video", "screen is " + screen.isHardwareAccelerated() );
Log.i("video", "video is " + video.isHardwareAccelerated() );
Log.w("video" , "How has focus " + video.findFocus() );
Log.w("video" , "video Buffer " + video.getBufferPercentage() );
Log.w("video" , "video Layer Type " + video.getLayerType() );
Log.w("video" , "video Visibility " + video.getVisibility() );
Log.w("video" , "video Screen On " + video.getKeepScreenOn() );
Log.w("video" , "video is Clickable " + video.isClickable() );
Log.w("video" , "video is Focusable " + video.isFocusable() );
Log.w("video" , "video is Visibility " + video.getVisibility() );
Log.w("video" , "video has a Holder " + (video.getHolder() == null) );
Log.w("video" , "video root View " + video.getRootView() );
Log.w("video" , "video is Opaque " + video.isOpaque() );
Log.w("video" , "video is Shown " + video.isShown() );
Thus resulting in the following LogCat:

These all show isHardwareAcceleration as true
Which still produces the error and Video with NO picture , Video
with only audio
What then produces the err=-19 error ?
