Only works in mmap'ed mode. -A <path+file> Path and filename to write archive images. See man strftime for possible tokens. -M <value> Maximum number of images to keep in archive. -E <value> Take a snapshot for the archive each <value> image. -R Swap left/right like a mirror. -U Swap top/bottom like a mirror. -G Do not use mmap'ed memory - needed only for certain cams -X Do not fork in daemon mode, good for testing/debbuging -Z 'commands' Execute <commands> after each image.
