I'm building an app that would apply various filters to data coming from the device camera's preview function and display the results in real-time. I have many questions, but I'll start with this one: is it possible to capture camera preview data without setting a preview display? e.g. Camera.setPreviewDisplay(surfaceholder)
I tried just not setting it and calling Camera.startPreview() ... but either I got an error or it never called the PreviewCallback (forgot which). The reason I ask is that, for the moment, I can only get this to work using two surfaceviews ... one for input and one for output. I z-order the output on top of the input so its not seen, however I suspect android is still rendering the original input to a surface ... in my case unnecessarily. Any thoughts on this question, or on my general approach would be appreciated. For example, I saw that NDK came out last Friday, would that be worth looking into?
