I'm new here and don't really familiar with how to post something here, so I hope this reach you.

So I was following this example https://code.google.com/p/javacv/source/browse/samples/FacePreview.java But I don't understand how gray variable manage to get it's value, all I know when I try to write the frame (the gray one) into sd card the result is the gray version of what shown on the screen. Is there a way to get the RGB version instead?

Thank you

Sure, do something like this: https://github.com/bytedeco/javacv/blob/master/samples/RecordActivity.java And please post on GitHub next time, thanks.
