See more:

here they are using this code to acquire video :

C#

hVideoSrc = vision.VideoFileReader; 
hVideoSrc.Filename = 'viptrain.avi'; 
hVideoSrc.VideoOutputDataType = 'single';

i would like to replace that part with:

C#

vid=videoinput('winvideo',1); 
start(vid); 
preview(vid);

how can i do that ? please help.
