  1. POFront Facing Camera Issue in IPhone 5S IOS 7
    text
    copied!<p>I have problem on IPhone 5S with front camera output, the same session resolution like rear camera. (<code>AVCaptureSessionPreset352x288</code>) and <code>kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange</code> setting for <code>kCVPixelBufferPixelFormatTypeKey</code>. I found some discussion on apple forum about exact issue, here is the link: <a href="https://discussions.apple.com/message/23150694#23150694" rel="nofollow">https://discussions.apple.com/message/23079639#23079639</a></p> <p>What is the problem? Please Help. </p> <p>Good output, rear-facing camera.</p> <pre><code>Printing description of imageBuffer: &lt;CVPixelBuffer 0xd5e2f30 width=352 height=288 pixelFormat=420v iosurface=0xd80e724 planes=2&gt;
