mgvideocrop - three issues #18

Closed krisny closed 8 years ago

1) I think it would be good if there was instructions to the user to select a cropping frame and double click to end the selection procedure. Maybe a printout in the command window.

2) I had some trouble getting the pos argument to work. The help file should probably specify with an example: croppedvideo = mgvideocrop(d,[20 40 30 50])

3) When specifying file name like this croppedvideo = mgvideocrop(d,[20 40 30 50],'newfilename') I get the following output:

_cropping video_ process in progress:100% Error using VideoReader/init (line 607) The filename specified was not found in the MATLAB path.

Error in VideoReader (line 172) obj.init(fileName);

Error in mgvideoreader (line 27) obj = VideoReader(fn);

Error in mgvideocrop (line 110) s = mgvideoreader(filename);

I guess the given filename should be 'newfilename.avi' . Writer needs the file extension.
