[Pyrolr]

Thanks for sharing this wonderful code Alan ,
i'm having issue with iOS - 8 orientation while the recording is ongoing , it record in same orientation though device orientation has change
If any one has solved this problem please suggest a way to solve this problem
Thanks

Here is the solution:

#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN(v)                 ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
//...

- (void)writeVideoFrame
{
     //...
     // draw each window into the context (other windows include UIKeyboard, UIAlert)
        // FIX: UIKeyboard is currently only rendered correctly in portrait orientation
        CGFloat width = _viewSize.width;
        CGFloat height = _viewSize.height;
        if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8") && UIInterfaceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation)) {
            width  = MAX(_viewSize.width, _viewSize.height);
            height = MIN(_viewSize.width, _viewSize.height);
        }

        dispatch_sync(dispatch_get_main_queue(), ^{
            UIGraphicsPushContext(bitmapContext); {
                for (UIWindow *window in [[UIApplication sharedApplication] windows]) {
                    [window drawViewHierarchyInRect:CGRectMake(0, 0, width, height) afterScreenUpdates:NO];
                }
            } UIGraphicsPopContext();
        });

        //...
}

- (CGContextRef)createPixelBufferAndBitmapContext:(CVPixelBufferRef *)pixelBuffer
{
    CVPixelBufferPoolCreatePixelBuffer(NULL, _outputBufferPool, pixelBuffer);
    CVPixelBufferLockBaseAddress(*pixelBuffer, 0);

    CGContextRef bitmapContext = NULL;
    bitmapContext = CGBitmapContextCreate(CVPixelBufferGetBaseAddress(*pixelBuffer),
                                          CVPixelBufferGetWidth(*pixelBuffer),
                                          CVPixelBufferGetHeight(*pixelBuffer),
                                          8, CVPixelBufferGetBytesPerRow(*pixelBuffer), _rgbColorSpace,
                                          kCGBitmapByteOrder32Little | kCGImageAlphaPremultipliedFirst
                                          );
    CGContextScaleCTM(bitmapContext, _scale, _scale);
    CGAffineTransform flipVertical = CGAffineTransformMake(1, 0, 0, -1, 0, _viewSize.height);
    CGContextConcatCTM(bitmapContext, flipVertical);

    if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8") && UIInterfaceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation)) {
        CGContextRotateCTM(bitmapContext, M_PI_2);
        CGContextTranslateCTM(bitmapContext, 0, -_viewSize.width);
    }
    if(SYSTEM_VERSION_LESS_THAN(@"8") && [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeLeft) {
        CGContextRotateCTM(bitmapContext, M_PI);
    }

    return bitmapContext;
}
