Video Object wont get accepted

I was trying the following code to accept video from webcam:

vidobj = videoinput('winvideo', 1, 'RGB24_640x480');

set(vidobj, 'FramesPerTrigger', 60);

triggerconfig(vidobj, 'manual');

start(vidobj);

trigger(vidobj);

data = getdata(vidobj, [1 Inf]);

........

which is giving me the error: No method 'getdata' with matching signature found for class 'imaq.winvideo1_1'.

Error in test2 (line 19) data = getdata(vidobj, [1 Inf]);

Any help will be appreciated, thanks

The second argument to the getdata command should be a single number, not a vector. You set the FramesPerTrigger property to 60, so if you call getdata with only one argument, it will return 60 frames:

 data = getdata(vidobj); % Will return 60 frames.

Maybe try getsnapshot(), or the new webcam add-on "Webcam support package" in R2014a http://www.mathworks.com/help/matlab/import_export/installing-the-webcams-support-package.html
