Camera: Compress webcam frames to fit the game's framesize

Browse Source 
The PSP camera keeps JPEG frames within the framesize from the video setup.
Go!Edit stores frames in 15KB slots and only takes frames that fit, so our
uncompressed-quality webcam frames were dropped and one frame got repeated
for the whole clip. Lower the JPEG quality until a frame fits.
