CameraController, 3GS and 3.0

[marcelo.emmerich]

First of all, thanks to everyone who contributed to this thread, it helped me a lot in implementing an app that samples the preview of the camera and do meaningful, AR-ish things with the raw pixels.

Mmm... but I think takePicture() is not as fast as the streammed video, I will make some tests...

Any other way to take a sample of the camera, without using a private API?

According to this thread it looks like there is a way of sampling the preview of the camera using the generic UIImagePickerController, however no details are presented, as the developer is under NDA. He gives a couple of hints though.

Hi rilocr,

Is there any way to get YUV image data from coreSurfaceBuffer ?

Thank you.

Hi natios,

Try releasing the coreSurfaceBuffer variable with CFRelease(coreSurfaceBuffer).

That's the only additional code I have.

Hi,

Yes, but you have to find a function to translate RGB to YUV, which I don't have... maybe ask google.

surface.baseAddress;

returns a buffer encoded as RGB32, and I am sure there are functions to translate a buffer format to another one.
