Access to Capture Video in SDK 4.0

[wlindner]

From what I've read it seems like with iPhone OS 4.0 we have more access to each frame of captured video in our apps.

I've briefly messed around with it and I've been looking primarily at the enhancements of AVFoundation, which now include AVCaptureDevice and a few other classes that should give me access to the video data. Unfortunately, I can't even create an AVCaptureDevice object because the AVFoundation doesn't import this header. When I open AVFoundation.h I see this at the bottom:

#if TARGET_OS_EMBEDDED
#import <AVFoundation/AVCaptureSession.h>
#import <AVFoundation/AVCaptureDevice.h>
#import <AVFoundation/AVCaptureInput.h>
#import <AVFoundation/AVCaptureOutput.h>
#import <AVFoundation/AVCaptureVideoPreviewLayer.h>
#endif

And for some reason it is not importing these headers. Shouldn't TARGET_OS_EMBEDDED include the iPhone?

So my questions are.

1. With 4.0, do we really have access to each frame of video data that we can manipulate to modify preview/captured video?

2. Do I need to use AVCaptureDevice to do this, if so, why is the iPhone not considered an EMBEDDED device?

iPhone OS 4.0 is under NDA and can't be disscused here.

Oh, wow. I had no idea o_0. So nothing can be discussed about it here? Not even if the functionality to manipulate video as it is being captured will be present with 4.0 officially comes out?

Hellow wlindner,

I have faced the same problem when trying to access AVCaptureSession. But After placing the code on that block as follows, the compiler errors have gone.

#if TARGET_OS_EMBEDDED

//Here you can capture the AVCaptureSession

#endif

Still I didnt run the project onto iPhone 4 device, so not sure whether its right or wrong. Moreover, I am sure what is meant by TARGET_OS_EMBEDDED! Is it specifying the iPhone device only or any other embedded device for apple?

If you have come out with a solution please share and that would be a great help to me.

As from other threads, if you build the application on device, then there will be no compiler errors. So, I would like to conclude: TARGET_OS_EMBEDDED means the installed os on device (iPhone).
