Hi all,
I got things happening, my sample test application worked fine i tried
initializing my camera in JPEG and saved as direct file in .jpg format, i
didn't do any conversion algorithm. I am not sure whether the same can be
used for Android's camera application since general gtk display requires RGB
data to be display real time image data in screen i believe.
Pls do give your comment
Cheers,
Suresh Kalidasan.
