Please help, Muhammad Anas Khan.

If you have the thumbnail image and the duration of the video then you have many options to overlay the duration onto the thumbnail image.

One example on the command line is to use ImageMagick: http://www.imagemagick.org/

If you prefer scripting then one way is to use PHP and its imaging capabilities: http://php.net/manual/en/book.image.php

In Ruby you can use the RVideo gem. The branch working with the latest version of ffmpeg is located here: http://github.com/howcast/rvideo
