I'm trying to get as good an image as possible from the camera, but can only find examples that captureStillImageAsynchronouslyFromConnection and then go straight to:
NSData *imageData = [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageSampleBuffer];
UIImage *image = [[UIImage alloc] initWithData:imageData];
JPEG being lossy and all, is there any way to get the data as PNG, or even just RGBA (BGRA, what-have-you?). AVCaptureStillImageOutput doesn't seem to have any other NSData* methods....
Actually looking at the CMSampleBufferRef, it seems like it's already locked as JPEG ~
formatDescription = <CMVideoFormatDescription 0xfe5e1f0 [0x3e5ac650]> {
mediaType:'vide'
mediaSubType:'jpeg'
mediaSpecific: {
codecType: 'jpeg' dimensions: 2592 x 1936
}
extensions: {(null)}
}
Is there some other way to take a full-res picture and get the raw data?
