Can this be done?
What libraries do I have to study?

The concept is that my App will record an event from two different views – using separate physical devices.
After the event the views will be compared via some form of inter iPad communication (Bluetooth? Dropbox?) in order to analyze the diferences and evaluate the event accordingly.

Any ideas?

This can be done like they do in movie editing. Timestamp every frame with a time synchronized startpoint. All devices would have to have time set to exact time via a timeserver or some such external service.

Then, if you are videoing a scene from disparate locations with multiple devices, the data can be uploaded to a central repository and be merged on multiple channels of a video editing program, with each synched to the common start point.

Beyond that, it depends on what you want to do with the data.

This is way beyond the capability of MobiOne’s limited toolset.

Canon’s DSLR SDK for the EOS cameras with live view have some interesting C++ libraries (or C# and VB.Net)

Again, it isn’t easy.

There are a couple way you can do it depending on the data you want to check.

You can use php and write data to a file, then use that to check against the other device.

Or, to utilize HTML5 look into the web socket feature.

Thanks guys at least I have a start point.

Not thinking about anything as rarified as video – my game is bridge – I’m thinking about comparing score sheets here.
