file to replace

I think that the issue appears because the library was tuned to work with
earlier devices (before iPhone 3Gs) and most probably new devices (iPhone 3Gs,
4, 4s, iPad 2) are give out the video stream in new format, so for this devices
need to change the library module setting. Now Apple supported only new device,
so I think no needed supported old device in this plugin.

the changes are next
