But still doesnt help

PYINC = /usr/include/python2.7

all:: vision.so

vision.so: vision.o fireflymv.o image.o
gcc -shared -W1 -ldc1394 -L$(PYLIB) -lpython2.7 -o vision.so vision.o fireflymv.o image.o

Binning is not a feature of IIDC, so vendors usually use different
Format_7 video modes to implement it. The maximal size of a 'binning'
video mode will thus be only half the maximal size of a normal mode.

F7M0: max size = 1280x1024
F7M1: max size = 640x1024 (horizontal binning)
F7M2: max size = 1280x512 (vertical binning)
F7M3: max size = 640x512 (full 2x2 binning)

Which mode corresponds to which binning depends on the model so
ultimately you'll have to check the camera docs to be sure.

To start using binning you just put the camera in the proper format_7
video mode and start capturing.
