Hi Androidphan, I have one doubt, i have one logitech QuickCam Connect which supports jpeg as raw pixel format unlike other camera's which support RGB or yuv as raw pixel format.
whether i needs to change anything in v4l2-camera.patch to make this work with android or it straight forward works. Because, in ur camera module, u are doing conversion fro yuv to jpeg during saving the picture. i need to modify this.
