Copy Subler functionality into my app

I have an application developed. I need someone to copy functionality from an existing opensource app (Subler) into my app. Get Perian and install it - [login to view URL] (It is required for the functionality below) The functionality i want to copy from Subler is as follows: 1. Get subler from [login to view URL] and install it. 3. Download this ([login to view URL]) file. This is the project you will be using later. It contains an mkv file which contains image based subtitles 2. Right click [login to view URL] and open with subler. 3. You will be presented with a screen (Notice that the vobsub (image based) are converted to Tx3g (text based). Watch this screen carefully.) - select all the checkboxes and click add. 4. Once added - select every checkbox and click save as. 5. Subler converts the .mkv to .m4v. The .m4v will contain text-based subtitles. I want someone to copy this functionality into my app (Subler does alot of other stuff as well that i don't need).
