• Grab single thumbnai or image from any video format.
• Grab single thumbnail or imagein any image format, recommended jpg, png.
• Grab single thumbnail or image from any specified duration e.g "00:00:15" represent grabbing thumbnail from 15th second of video.
• Grab single thumbnail or image in any specified size or in default video size.

Grab multiple thumbnails or images

• Grab multiple thumbnails or images from any video format.
• Grab multiple thumbnails or images in any image format, recommended jpg, png.
• Grab multiple thumbnails or images in any specified numbers. e.g No_of_thumbs=10 means grab 10 thumbnails from video.
• Grab multiple thumbnails or images from any specified time interval. e.g Start_Time="00:00:10" means start grabbing or capturing thumbnails from 10th second of video.

Grab 20 thumbnails from video starting from duration 00:01:00 and after every 15 seconds.

string outfile = m_handler.Grab_Multiple_Image(filename, _ffmpegpath, InputPath, OutputPath, 20, "00:01:00", "00:00:15", "jpg");

// This will generate 20 thumbnails starting from position 00:01:00.
