I am trying to display a filtered camera preview, using onPreviewFrame() callback.

The problem is that when i remove this line: mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

to hide the preview, the app crashes. The log reads: 08-19 15:57:51.042: ERROR/CameraService(59): registerBuffers failed with status -38

What does this mean? Is this documented anywhere?

I am using the CameraPreview from the SDK APIDemos: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/CameraPreview.html
