  1. POHow can I increase ScreenCaptureView efficiency on iPad?
    text
    copied!<p>I've been tasked with a new iOS project. As part of this, I am essentially looking to take a series screenshots of a UIView with it's subviews, and compile them in to a video file.</p> <p>I have searched about, and most topics on this reference <a href="http://codethink.no-ip.org/wordpress/archives/673" rel="nofollow">ScreenCaptureView</a>, which I have tried out and it works!</p> <p>I am using iOS SDK 5.1, and have this compiled with the -fno-objc-arc applied to ScreenCaptureView.m in the build phases section.</p> <p>Before reading further, please note that I do not always have access to hardware to test on, and have currently only tested in the Simulator. When I get access to equipment to test on I shall update.</p> <p>This is great on the iPhone, I find that because of the screen size this works smoothly and doesn't seem to lag at all. I do get the occasional dropped frame, but that isn't my concern with this question.</p> <p>I'm creating an app to record the screen on either the iPhone or the iPad. </p> <p>When I am using the iPad simulator, the efficiency of ScreenCaptureView drops significantly. I find that, presumably due to the resolution of the iPad display, it's having to work a lot harder to capture the screen and write it to a frame.</p> <p>The video becomes jerky and misses a lot of frames.</p> <p>How can I increase the efficiency of the ScreenCaptureView method, or is there another method I can use to capture what is displayed in a UIView?</p> <p>I admit I am very new to image manipuation/video work in general, and have no experience outside to draw on.</p> <p>Many thanks!</p>
