iPad crashing when linking with CoreVideo or CoreMedia

Question

Hi there,

I have an application that runs fine on the simulator.

When trying to run on the actual iPhone, I get link errors that require the CoreVideo and CoreMedia frameworks - and then the application runs fine on the iPhone hardware and the iPhone simulator.

Unfortunately, as soon as I do that, the application crashes on the iPad simulator (and according to some report - on the iPad hardware too) - until I REMOVE the CoreMedia and CoreVideo frameworks... But then again it doesn't link for the iPhone hardware.

Catch 22...

I searched the internet high-and-low, but found no answer. I tried weak-linking to these frameworks, but is still didn't help - the iPad simulator crashes like mad...

Is there maybe a way to add a framework to a specific application?

EDIT
Based on Michal's comment, here's some more information.
1. I need these libraries for the h/w, in order to successfully link with the ZXing QR code scanning widget.
2. The iPad version of my software crashes as soon as it launches with the following error:

Attaching to process 73137. dyld: Library not loaded: /System/Library/Frameworks/CoreMedia.framework/CoreMedia Referenced from: /Users/admin/Library/Application Support/iPhone Simulator/3.2/Applications/CF1E8FD0-3E84-495F-B2CB-3A2BF5F1F916/myappname.app/myappname

CoreVideo and CoreMedia are only available on iOS 4.0 and above. I presume the iPad simulator version you're trying to run is iPhone OS 3.2? If so it will crash unless you weak leak those frameworks and put appropriate conditional code checks around code that uses them.
