Building

• OS X 10.9

• Xcode 5.0.2

• ./build_debug.sh - Builds a debug release (verbose logging) in bin/screen-recording

• ./build_release.sh - Builds a regular release (no logging) in bin/screen-recording

Design

• AVCaptureScreenInput is used to generate the screen recording.
• Code from Square's Zapp open source project is used for finding window information and creating a croprect.
• Apple's ScreenShack example was helpful for identifying proper API usage.
• focusPid from the Amethyst project didn't work on Android and was flaky for iOS. Instead AppleScript is used to focus the window.
