QuickTime For Java
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. QTJ has been deprecated by Apple. History Owen W. Linzmayer, in ''Apple Confidential 2.0'', traced 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. Ported to the Mac OS, it was developed under the code-name "Biscotti", and first released as a public beta in 1999. 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 In 2003, Apple issued a ...

Library (computing)
In computing, a library is a collection of System resource, resources that can be leveraged during software development to implement a computer program. Commonly, a library consists of executable code such as compiled function (computer science), functions and Class (computer programming), classes, or a library can be a collection of source code. A resource library may contain data such as images and Text string, text. A library can be used by multiple, independent consumers (programs and other libraries). This differs from resources defined in a program which can usually only be used by that program. When a consumer uses a library resource, it gains the value of the library without having to implement it itself. Libraries encourage software reuse in a Modular programming, modular fashion. Libraries can use other libraries resulting in a hierarchy of libraries in a program. When writing code that uses a library, a programmer only needs to know how to use it not its internal d ...

Java OpenGL
Java OpenGL (JOGL) is a wrapper library that allows OpenGL to be used in the Java programming language. It was originally developed by Kenneth Bradley Russell and Christopher John Kline, and was further developed by the Game Technology Group at Sun Microsystems. Since 2010, it has been an independent open-source project under a BSD license. It is the reference implementation for Java Bindings for OpenGL (JSR-231). JOGL allows access to most OpenGL features available to C language programs through the use of the Java Native Interface (JNI). It offers access to both the standard GL* functions along with the GLU* functions; however the OpenGL Utility Toolkit (GLUT) library is not available for window-system related calls, as Java has its own windowing systems: Abstract Window Toolkit (AWT), Swing, and some extensions. Design The base OpenGL C API, as well as its associated Windowing API, are accessed in JOGL via Java Native Interface (JNI) calls. As such, the underlying sys ...

Ogg Vorbis
Vorbis is a free and open-source software project headed by the Xiph.Org Foundation. The project produces an audio coding format and software reference encoder/decoder (codec) for lossy audio compression, libvorbis. Vorbis is most commonly used in conjunction with the Ogg container format and it is therefore often referred to as Ogg Vorbis. Version 1.0 of Vorbis was released in May 2000. Since 2013, the Xiph.Org Foundation has stated that the use of Vorbis should be deprecated in favor of the Opus codec, an improved and more efficient format that has also been developed by Xiph.Org. Name Vorbis is named after the character Exquisitor Vorbis in the '' Discworld'' novel '' Small Gods'' by Terry Pratchett. The Ogg format is named after ''ogging'', jargon from the computer game ''Netrek''. Development Vorbis is a continuation of audio compression development started in 1993 by Chris Montgomery. Intensive development began following a September 1998 letter from the Fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DivX
DIVX (Digital Video Express) is a discontinued digital video format. Created in part by Circuit City, it was an unsuccessful attempt to create an alternative to video rental in the United States. The format's poor reception from consumers resulted in major financial losses for Circuit City and is credited with being part of the company's downfall. Format DIVX was a rental format variation on the DVD player in which a customer would buy a DIVX disc (similar to a DVD) for approximately US$4.50, which was watchable for up to 48 hours from its initial viewing. After this period, the disc could be viewed by paying a continuation fee to play it for two more days. Viewers who wanted to watch a disc an unlimited number of times could convert the disc to a "DIVX silver" disc for an additional fee. "DIVX gold" discs that could be played an unlimited number of times on any DIVX player were announced at the time of DIVX's introduction, but no DIVX gold titles were ever released. Eac ...

Audio Interchange File Format
Audio Interchange File Format (AIFF) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. The format was developed by Apple Inc. in 1988 based on Electronic Arts' Interchange File Format (IFF, widely used on Amiga systems) and is most commonly used on Apple Macintosh computer systems. The audio data in most AIFF files is uncompressed pulse-code modulation (PCM). This type of AIFF file uses much more disk space than lossy formats like MP3—about 10 MB for one minute of stereo audio at a sample rate of 44.1 kHz and a bit depth of 16 bits. There is also a compressed variant of AIFF known as AIFF-C or AIFC, with various defined compression codecs. In addition to audio data, AIFF can include loop point data and the musical note of a sample, for use by hardware samplers and musical applications. The file extension for the standard AIFF format is .aiff or .aif. For the compressed format the preferred suffi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sorenson Codec
Sorenson Media was an American software company specializing in video encoding technology. Established in December 1995 as Sorenson Vision, the company developed technology which was licensed and ultimately acquired from Utah State University. The company first announced its codec (compression and decompression tool) at a developer’s preview at MacWorld Expo in January 1997. One of the company's best known products is the Sorenson Video codec licensed to Apple Inc. for their QuickTime 3.0 software. Since its release, Sorenson Media’s video encoding technology was used in Apple's trailer web site and video clips for film studios such as Disney, Lucasfilm, MGM, and Paramount, as well as Apple's iTunes music videos, before the switch to the industry standard H.264 format. The company was led by its chairman and founder James Lee Sorenson (son of James LeVoy Sorenson); its final president and CEO was Patrick Nola. The company filed for Chapter 11 bankruptcy in October ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Audio Coding
Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. It was developed by Dolby, AT&T, Fraunhofer and Sony, originally as part of the MPEG-2 specification but later improved under MPEG-4.ISO (2006ISO/IEC 13818-7:2006 – Information technology — Generic coding of moving pictures and associated audio information — Part 7: Advanced Audio Coding (AAC), Retrieved on 2009-08-06ISO (2006, Retrieved on 2009-08-06 AAC was designed to be the successor of the MP3 format (MPEG-2 Audio Layer III) and generally achieves higher sound quality than MP3 at the same bit rate. AAC encoded audio files are typically packaged in an MP4 container most commonly using the filename extension .m4a. The basic profile of AAC (both MPEG-4 and MPEG-2) is called AAC-LC (''Low Complexity''). It is widely supported in the industry and has been adopted as the default or standard audio format on products including Apple's iTunes Store, Nintendo's Wii, DSi and ...

MPEG-4
MPEG-4 is a group of international standards for the compression of digital audio and visual data, multimedia systems, and file storage formats. It was originally introduced in late 1998 as a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC 1/SC29/WG11) under the formal standard ISO/IEC 14496 – ''Coding of audio-visual objects''. Uses of MPEG-4 include compression of audiovisual data for Internet video and CD distribution, voice (telephone, videophone) and broadcast television applications. The MPEG-4 standard was developed by a group led by Touradj Ebrahimi (later the JPEG president) and Fernando Pereira. Background MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video and VRML objects), support for externally specified ...

MPEG-1
MPEG-1 is a Technical standard, standard for lossy compression of video and Audio frequency, audio. It is designed to compress VHS-quality raw digital video and CD audio down to about 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital Cable television, cable/Satellite television, satellite TV and digital audio broadcasting (DAB) practical. Today, MPEG-1 has become the most widely compatible lossy audio/video format in the world, and is used in a large number of products and technologies. Perhaps the best-known part of the MPEG-1 standard is the first version of the MP3 audio format it introduced. The MPEG-1 standard is published as International Organization for Standardization, ISO/International Electrotechnical Commission, IEC 11172, titled ''Information technology—Coding of moving pictures and associated audio for digital storage media at up to about 1.5 Mbit/s''. The standard consists of the follow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namespace
In computing, a namespace is a set of signs (''names'') that are used to identify and refer to objects of various kinds. A namespace ensures that all of a given set of objects have unique names so that they can be easily identified. Namespaces are commonly structured as hierarchies to allow reuse of names in different contexts. As an analogy, consider a system of naming of people where each person has a given name, as well as a family name shared with their relatives. If the first names of family members are unique only within each family, then each person can be uniquely identified by the combination of first name and family name; there is only one Jane Doe, though there may be many Janes. Within the namespace of the Doe family, just "Jane" suffices to unambiguously designate this person, while within the "global" namespace of all people, the full name must be used. Prominent examples for namespaces include file systems, which assign names to files. Some programming languages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Package
A Java package organizes Java classes into namespaces, providing a unique namespace for each type it contains. Classes in the same package can access each other's package-private and protected members. In general, a package can contain the following kinds of types: classes, interfaces, enumerations, records and annotation An annotation is extra information associated with a particular point in a document or other piece of information. It can be a note that includes a comment or explanation. Annotations are sometimes presented Marginalia, in the margin of book page ... types. A package allows a developer to group classes (and interfaces) together. These classes will all be related in some way – they might all have to do with a specific application or perform a specific set of tasks. Programmers also typically use packages to organize classes belonging to the same category or providing similar functionality. Using packages In a Java source file, the package that this file' ...
