Camera framework requires 352x288, and 320x240 frames for video preview and video

may abort when entering video mode, or start video recording.
Also truned off switching fake frames, leaving only the checker board.

These two tasks (starting the camera device, and starting working thread that pulls frames
from the started camera device) should be clearly separated, and should not be combined in
one method (as it was with the 'startCapturing' method).
