It is possible to do that?
please give me a hint.

I would investigate ffmpeg, specifically libavcodec - this will allow you to convert static images in to a movie file (assuming you can get it to compile for iOS).
As far as adding to the iPod library is concerned, you aint going to be able to do that - you can read from the library from within an iOS app, but not write to it.

I've searched the web for having a good resource to implement a code in objective c that is able to record a video of the screen of the Ipad while the user is doing some actions to capture his performance, but I didn't get a clue. Is there anyway to make it possible?
You can download sample from the link below provided by Apple.

I would like to interact with the mp3 player the iPhone: Is possible to save a .mp3 file into Iphone music library programmatically?
If you aren't planning on distributing this through Cydia then the answer is no this isn't possible. However, if you are going the jail break route check out libiPodImport by H2CO3.

Is there a way to not stop the iPod music when I start my app in the iPhone?
Because when my app is launched, the music stops.
Thanks!
It depends what code and sound Library you are using in your application
adding MediaPlayer.framework will help you solve the issue quickly

I would like to add metadata to mp3 files in C/Objective-C (OS X).
I found several libraries (e.g. id3lib), but I have no clue on how to compile them.
Are there any tutorials on how you can do that? Is there any other framework for C/Objective-C to write ID3 tags to an MP3 file (song name, artist and coverart)?
Take a look at the id3lib Library Documentation. It provides a quick tutorial.
