* You can extract images from a video, or create a video from many images:

For extracting images from a video:

ffmpeg -i foo.avi -r 1 -s WxH -f image2 foo-%03d.jpeg

This will extract one video frame per second from the video and will output them in files named `foo-001.jpeg', `foo-002.jpeg', etc. Images will be rescaled to fit the new WxH values.

If you want to extract just a limited number of frames, you can use the above command in combination with the -vframes or -t option, or in combination with -ss to start extracting from a certain point in time.

For creating a video from many images:

ffmpeg -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi

public DataTable GetRols()
     {
        DataTable DT = new DataTable();
        string Query = "GetRols";
        DT = _dbHelper.ExecuteDataTable(Query);
        return DT;
     }

private void GetRols()
        {
            Cls_Role Role = new Cls_Role();
            cmbRole.DataSource = Role.GetRols();
            cmbRole.DisplayMember = "Role_Name";
            cmbRole.ValueMember = "Role_ID";
        }
