An AVAsset instance is a collection of one or more pieces of media data (audio and video tracks) that are intended to be presented or processed together, each of a uniform media type, including (but not limited to) audio, video, text, closed captions, and subtitles. The primary class that the AV Foundation framework uses to represent media is AVAsset. A QTMedia object represents the data associated with a QTTrack object. In turn, a QTTrack object is associated with a single QTMedia object. A QTTrack object represents the ordering and other characteristics of media data in a QTMovie object, such as a single video track or audio track. A QTMovie object is associated with instances of the QTTrack class. In QTKit, the QTMovie object represents a playable collection of media data. More information on these tools can be found in their respective man pages (for example, type man nm from the Terminal application).īack to Top Working with Audiovisual Media Resources Representing Audiovisual Media Resources MyQuickTimeApp.app/Contents/MacOS/MyQuickTimeApp (for architecture i386):Ġ0003025 (_TEXT,_text) non-external.

Otherwise, if you are already using the modern frameworks, you probably need only update those portions that are using the now deprecated QuickTime APIs. If your application is using older frameworks such as Carbon it may require significant changes to modernize it. By always using the latest tools, you can keep your application up to date with the current versions of all the frameworks. As frameworks evolve through various releases, APIs are introduced or deprecated and behaviors of existing APIs may occasionally change.

Make sure and always build your application using the latest version of Xcode and the Mac OS X SDK. Identifying Deprecated APIs with Xcodeīuild your application with Xcode to identify all the APIs that need updating. To get a quick look at your existing binary to see what QuickTime API's you are using, use the process described in Checking your existing binary with nm. To understand what is required to modernize your entire application, build your application with Xcode and the latest SDK as described in Identifying Deprecated APIs with Xcode. This document describes the mapping of the QTKit classes and methods to the newer AV Foundation classes to help you get started working with AV Foundation objects and their associated methods to accomplish a variety of tasks. Introduced in OS X 10.4, QTKit provides a set of Objective-C classes and methods designed to handle the basic tasks of playback, editing, export, audio/video capture and recording, in addition to a number of other multimedia capabilities. AV Foundation is also recommended for transitioning existing apps based on QTKit.

The services offered by this framework include the following: The framework includes many Objective-C classes, with the core class being AVAsset this class presents a uniform model and inspection interface for all forms and sources of audiovisual media. Introduced in OS X 10.7, AV Foundation is a framework that you can use to play and create time-based audiovisual media.
