Sample Code
This page lists new and recently changed sample code. Most sample code has a revision history, which details additions and changes since the previous version. Look for "Revision History" at the bottom of the sample code page.

Items are listed in reverse chronological order by publication date. To see the list sorted by the type of revision, click Sort by Revision Type. Items published for the first time (First Version) will be at the top of the list, followed by items with new or changed content (Content Update), followed by items with small fixes, such as typos and format errors, but no significant content changes (Minor Change).

New and updated sample code is announced in the bi-weekly Apple Developer Connection News, available as an option to ADC members. See the Membership Overview page for details on joining.

2008-08-14 OpenGLScreenSnapshot (HTML) (DMG) (ZIP)
Code refactoring.
 Content Update OpenGL
2008-07-30 GLSL Basics Cocoa (HTML) (DMG) (ZIP)
Refactored the sample code to better demonstrate the interaction of OpenGL APIs with an OpenGL view. Moved the GLSL program object instantiation into its own basic class. Moved the GLSL hardware check code into its a separate file. Consistent use of float math library functions for pattern and palette generation. Animation continues during window resizing. Consistent use of doubles and their OpenGL equivalents during geometry generation. Updated the Xcode project to use the new format. Updated the NIB to use the new format. Added a simple GLUT string class.
 Content Update OpenGL
2008-06-02 MyMovieFilter (HTML) (DMG) (ZIP)
Updated to use a Core Animation layer-backed view.
 Content Update QuickTime
2008-05-09 WhackedTV (HTML) (DMG) (ZIP)
Fixed two bugs: (1) "Select Output Format" in the audio dialog failed with error -206 if the source audio were set to 20 or 24 bits on an Intel Mac. The source format is 24-bits aligned low in 32-bits. WhackedTV was setting this as the default output format. But QuickTime movies can only contain packed samples. Added a utility function to conform the output format for movie-safety. (2) Began preferring the kQTSGAudioPropertyID_CodecSpecificSettingsArray property to the kQTSGAudioPropertyID_MagicCookie property. See QuickTimeComponents.h for an explanation of the differences between these properties, and why CodecSpecificSettingsArray should always be preferred over MagicCookie.
 Content Update QuickTime
2008-04-24 CIColorTracking (HTML) (DMG) (ZIP)
More comments. Fixed some errors in the project.
 Content Update Carbon, Cocoa, Games, Quartz
2008-04-24 LiveVideoMixer (HTML) (DMG) (ZIP)
