  2. You can use any hex editor to change the fourcc. I don't know what the fourcc is for 16 bit greyscale.

    And, of course, if the data isn't 16 bit greyscale you'll get garbage. And you'll need a decoder for whatever fourcc you use.

    According to there is a 16 bit greyscale fourcc, "Y16 ". But I don't see any decoder for it.
