QuickTime for Java or QTJ is a software library that allows software written in the Java programming language to provide multimedia functionality, by making calls into the native QuickTime library. In practice, it allows Java applications on Mac OS, Mac OS X and Microsoft Windows to support the capture, editing, playback, and export of many different media formats and codecs.
QuickTime is an extensible multimedia framework developed by Apple Inc., capable of handling various formats of digital video, picture, sound, panoramic images, and interactivity.First made in 1991, the latest Mac version, QuickTime X, is currently available on Mac OS X Snow Leopard and newer. Apple ceased support for the Windows version of QuickTime in 2016, and ceased support for QuickTime 7. QuickTime Player lets you make common movie edits like trim, rearrange, and rotate. You can also split a movie into multiple clips and manipulate each one individually. How to edit a movie. Record your Mac screen.

- QuickTime 6 was initially available for Mac OS 8.6 – 9.x, Mac OS X (10.1.5 minimum), and Windows 98, Me, 2000, and XP. Development of QuickTime 6 for Mac OS slowed considerably in early 2003, after the release of Mac OS X v10.2 in August 2002. QuickTime 6 for Mac OS continued on the 6.0.x path, eventually stopping with version 6.0.3.
- In Mac OS X v10.6 and newer, since the QuickTime X (QT Player v10.x) AVFoundation playback structure no longer posses an open codec architecture for 3rd party plugins or components installation, you can't drop AVI files that aren't encoded as Mjpeg video with PCM onto QuickTime X player for direct playback.
- The QuickTime Player app lives a lonely quiet life in the Applications folder of many Mac users. It’s often ignored because folks assume it’s simply a video playback app.
QTJ has been deprecated by Apple.[1]
History[edit]
Owen W. Linzmayer, in Apple Confidential 2.0, traces QuickTime for Java's genesis back to Kaleida Labs, a spin-off company created by Apple Computer and IBM, noting that it and some Unicode text classes were the only Mac software salvaged from the four-year, $150 million disaster.[2] Ported to the Mac OS, it was developed under the code-name 'Biscotti', and first released as a public beta in 1999.[citation needed] Later versions were installed by default with Mac OS and Mac OS X, and were an optional part of the QuickTime install for Windows.
QTJ 6.1[edit]
In 2003, Apple issued a Java 1.4.1 implementation that broke any QTJ applications that tried to run under 1.4.1 on Mac OS X. The underlying problem was Apple's move from Carbon to Cocoa for their AWT implementation, and the removal of a Java-to-native library called 'JDirect' that QTJ relied on. QTJ applications could still run under Java 1.3.1, but apps that did not specify the version of Java they required, or that needed 1.4 features, were rendered unusable.
Later that year, Apple released a new version of QTJ that dealt with the incompatibilities, by offering a compatible but scaled-down version of the GUI classes. This 6.1 version of QTJ also radically changed the API, so that instead of having developers create GUI components and associate
Movie
s or other renderable objects with them, the developers now needed to start with the Movie
and request a suitable component from a factory. The new version also neglected to provide a component to show a visual preview of the input from a capture device, such as a webcam or camcorder.[3]Design[edit]
QTJ lays an object-oriented API on top of the native C-based QuickTime library. It does this by associating common
struct
s and the functions that work with them into classes. For example, the Movie
struct is the basis of the class quicktime.std.movies.Movie
, with functions like NewMovieFromFile
and GetMovieTrackCount
becoming the instance methods fromFile()
and getTrackCount()
respectively. The result is more like a genuine object-oriented API than other C-to-Java adaptations (such as JOGL, which dumps the OpenGL header files into classes with thousands of static methods).[4]The Cocoa-based QTKit is a similar attempt to put an object-oriented layer atop the procedural QuickTime library, using Objective-C.
Apple's use of the top-level package name
quicktime
violates the Java Language's Specification convention that packages use a reverse-domain-name scheme, such as com.apple.quicktime
. However, as Apple owns the 'QuickTime' trademark, there is no realistic chance of a namespace collision, the prevention of which is the purpose of the package naming convention.It is important to remember that QTJ is not a Java implementation of QuickTime, it is a Java wrapper around native QuickTime calls. For this reason, it can only run on systems that have the QuickTime libraries installed, namely the classic Mac OS (which is no longer supported), Mac OS X, and Windows.
Features[edit]
QTJ offers access to most of the native QuickTime library, including
- Playback
- Editing
- Capture
- Graphic import and export
- Movie import and export
- Sample-level access
As a wrapper around QuickTime, QTJ also inherits support for a vast collection of media formats and codecs, including MPEG-1, MPEG-4, H.264, AAC, Sorenson Video, Flash, 3GPP, WAV, AIFF, and more. Since QuickTime itself can be extended, QTJ can pick up support for formats such as DivX and Ogg Vorbis through the use of third-party QuickTime components.
Code Example[edit]
The following example shows an AWT file-selection dialog and then tries to import and play the selected media file.
Most of the code in this example involves itself with setting up the GUI. The only calls to QTJ are the calls to
OpenMovieFile.asRead()
and Movie.fromFile()
, which create a QuickTime movie from the specified file, and the calls to create an AWT component from the QTFactory
. This example puts the movie into the frame and immediately starts playing it; if a control bar (aka a 'scrubber') were desired, you would create a MovieController
from the Movie
and then create a component from the controller, rather than from the movie.Quicktime 10 For Mac
Status and Outlook[edit]
QTJ's acceptance is limited by its nature as a wrapper around Apple's proprietary QuickTime library. It does not exist for any platform other than Mac and Windows, and cannot until and unless Apple ports QuickTime to another platform, such as Linux.
Currently most of QTJ is broken on recent Windows-running computers. Windows machines that use the no-execute (NX) page-protection security feature of recent CPUs cannot run even the demos without changing the configuration. This can be easily verified by a developer via a test-run of one of the demos coming with QTJ. An 'execution protection violation' is reported and the program is aborted by Windows. This renders QTJ unsuitable for end-user application development due to the necessary complicated configuration of the NX feature.
Following the 2003 release of QTJ 6.1, Apple has made few updates to QTJ, mostly fixing bugs. Notably, QuickTime 7 was the first version of QuickTime not to be accompanied or followed by a QTJ release that wrapped the new native API's. QuickTime 7's new API's, such as those for working with metadata and with frame-reordering codecs, are not available to QTJ programmers. Apple has also not offered new classes to provide the capture preview functionality that was present in versions of QTJ prior to 6.1. Indeed, QTJ is dependent on some native API's that Apple no longer recommends, most notably QuickDraw.
