Error using lansvd

Hello, I got the error by running the algorithms:

Hi @xKlask , I am sorry for my delayed feedback to you, and thanks for opening this issue, I will check it soon as possible due to my limited time

Hi,

I'm having a similar issue.

Error using VideoReader/init (line 619)
Could not read file due to an unexpected error. Reason: Unable to initialize the video obtain properties

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

Error in load_video_file (line 19)
  xyloObj = VideoReader(file);

Error in process_video (line 26)
video = load_video_file(inFile);

Error in main>pushbutton_process_Callback (line 200)
  stats = process_video(method_id,algorithm_id,inputFileName,outputFileName);

Error in gui_mainfcn (line 95)
        feval(varargin{:});

Error in main (line 42)
    gui_mainfcn(gui_State, varargin{:});

Error in

Error while evaluating UIControl Callback.

This occurs for some of the algorithms I tried out with a video other than the demo.avi.

Does it got to do with the video decoding process?

PS: I'm running it on 2017b MATLAB on Ubuntu 16.04
