i interfaced my handycam using a video capture device.it got detected in image acquisition toolbox.Was able to view in the preview also,but when i run the program,i get the following error,......
*??? Error using ==> videoinput.videoinput at 328
The FORMAT specified is not supported by this device. See IMAQHWINFO(ADAPTORNAME).
Error in ==> testvid at 9
vid = videoinput('winvideo',2,'YUY2_720X480');*
when i used the IMAQHWINFO(ADAPTORNAME),got the following output
*obj = videoinput('winvideo', 2);
obj_info = imaqhwinfo(obj)
obj_info =
AdaptorName: 'winvideo'
DeviceName: 'SMI Grabber Device'
MaxHeight: 480
MaxWidth: 720
NativeDataType: 'uint8'
TotalSources: 2

Please try
devinfo = imaqhwinfo('winvideo', 2);
devinfo.SupportedFormats
Notice for example that you are asking for a format with 720 x 480, but the camera is saying it is 480 x 720.

Thank u for your suggestion,i tried it out.. *devinfo = imaqhwinfo('winvideo', 2); devinfo.SupportedFormats
ans =
'UYVY_720x480' 'UYVY_720x576'*
i changed the format to 720 X 480....
still the same problem persists....
Is there any other area where i am going wrong
