Cannot Acquire full camera resolution in OS X with Image acquisition toolbox and 1394b camera

I'm trying to acquire movie sequence with PointGrey Flea2 FW800(IEEE1394b) camera and Image Acquisition toolbox in OS X. (My matlab version is 2013a, in OS X)

I'm succeed with default mode,

vid = videoinput('dcam', 1, 'F7_Y16_324x244_mode1');

However, when I try to acquire full resolution,

vid = videoinput('dcam', 1, 'F7_Y16_648x488_mode0')

or

vid = videoinput('dcam', 1, 'F7_Y8_648x488_mode0');

the preview(vid) shows the error below.

dcam: Unable to set the bytes per packet on the camera.

I am not sure its mac-specific bug or some comparability issue with PTG camera and matlab. Other parts(including HW triggering) are perfect, but it bothers me few days.

Hi, I have osX 10.9.2. I used

vid=videoinput('macvideo',1,'YCbCr422_1280x720')

I hope help you

I believe that firewire cams are effectively IP cameras for MATLAB purposes, which would have a fairly different treatment than the built in macvideo .
