i have a code that works perfectly for motion detection and tracking using webcam. But now i want to convert this code in which we can give video (mp4,avi etc) as an input. i have attached zip file of whole code. Run GUI and code will execute properly.

Convert the webcam() call into a VideoReader() call. Convert the snapshot() calls into readFrame() calls.

my code is like this

current_camera = webcam(Camera_number);

current_frame = snapshot(current_camera);

previous_frame = current_frame;

gray_current_frame = double(rgb2gray(current_frame));

gray_previous_frame = double(rgb2gray(current_frame));

. . . but when i am using VideoReader and readFrame it gives me below error

Undefined function 'readFrame' for input arguments of type 'VideoReader'.

Use the VideoReader read() method.
