Beep media file

The Beep Media Player (BMP) was a free audio player, based on the XMMS multimedia player. The lead developer was Milosz “deadchip” Derezynski[1]. The BMP is mainly a port of XMMS to GTK+ 2 and, as such, integrates better with the look and feel of more recent versions of GNOME, Xfce, and, if using the GTK-QT theme engine for KDE, KDE desktop environments. Like XMMS, BMP looks like Winamp and even supports Winamp and XMMS skins. BMP supports most of the audio file formats supported by XMMS, since the main difference between the plug-ins used in both players is the graphical widget toolkit used for 'About' and configuration dialog boxes. However, BMP cannot directly use XMMS plugins because of the differences in GTK versions--XMMS plug-ins requiring configuration will crash because some GTK 1.x symbols clash with the ones in GTK 2.x, so plug-ins have to be ported to GTK 2.x in order to compile. XMMS plug-ins that have already been compiled may work if copied to BMP's plug-in directory; however, this is unsupported, and any dialog boxes created by the plug-ins will probably make BMP segfault.

AVI media file

Audio Video Interleave, known by its acronym AVI, is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows technology. AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback. Like the DVD video format, AVI files support multiple streaming audio and video, although these features are seldom used. Most AVI files also use the file format extensions developed by the Matrox OpenDML group in February 1996. These files are supported by Microsoft, and are unofficially called "AVI 2.0".

AMV media file

Advanced Systems Format (formerly Advanced Streaming Format, Active Streaming Format) is Microsoft's proprietary digital audio/digital video container format, especially meant for streaming media. ASF is part of the Windows Media framework.ASF is based on serialized objects which are essentially byte sequences identified by a GUID marker.The format does not specify how (i.e. with which codec) the video or audio should be encoded; it just specifies the structure of the video/audio stream. This is similar to the function performed by the QuickTime, AVI, or Ogg container formats. One of the objectives of ASF was to support playback from digital media servers, HTTP servers, and local storage devices such as hard disk drives.The most common filetypes contained within an ASF file are Windows Media Audio (WMA) and Windows Media Video (WMV). Note that the file extension abbreviations are different from the codecs which have the same name. Files containing only WMA audio can be named using a .WMA extension, and files of audio and video content may have the extension .WMV. Both may use the .ASF extension if desired.ASF files can also contain objects representing metadata, such as the artist, title, album and genre for an audio track, or the director of a video track, much like the ID3 tags of MP3 files. It supports scalable media types and stream prioritization; as such, it is a format optimized for streaming.The ASF container provides the framework for digital rights management in Windows Media Audio and Windows Media Video. An analysis of an older scheme used in WMA reveals that it is using a combination of elliptic curve cryptography key exchange, DES block cipher, a custom block cipher, RC4 stream cipher and the SHA-1 hashing function.

AIFF media file

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 co-developed by Apple Computer in 1988 [1] 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 a standard AIFF file is uncompressed pulse-code modulation (PCM). There is also a compressed variant of AIFF known as AIFF-C or AIFC, with various defined compression codecs.Standard AIFF is a leading format (along with SDII and WAV) used by professional-level audio and video applications, and unlike the better-known lossy MP3 format, it is non-compressed (which aids rapid streaming of multiple audio files from disk to the application), and lossless. Like any non-compressed, lossless format, it uses much more disk space than MP3 -- about 10MB for one minute of stereo audio at a sample rate of 44.1kHz and a sample size of 16 bits. 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 variants it is supposed to be .aifc, but .aiff or .aif are accepted as well by audio applications supporting the format.

AVS media file

Development of AVS was initiated by the government of the People's Republic of China. Commercial success of the AVS standard would not only reduce China's royalty/licensing payments to foreign companies, it would presumably earn China's electronics industry recognition among the more established industries of the developed world, where China is still seen as an outlet for mass production with limited indigenous design capability.In January 2005, the AVS workgroup submitted their draft report to the Information Industry Department (IID). On March 30, 2005, the first trial by the IID approved the video portion of the draft standard for a public showing time.The dominant audio/video compression codecs, MPEG and VCEG, enjoy widespread use in consumer digital media devices, such as DVD players. Their usage requires Chinese manufacturers to pay substantial royalty fees to the mostly-foreign companies that hold patents on technology in those standards. For example, as of 2006, licenses ranging from $2.50 to $4 already make up about ten percent of the cost for a contract-manufactured DVD player unit.According to the state-run media, a key consideration of AVS was to reduce foreign dependence on core intellectual properties used in digital media technology. Proposed as a national standard in 2004, AVS had a targeted royalty of 1 RMB (or about $0.10 USD) per player. On 30 April 2005, AVS standard video officially passed the public show and became the national standard.AVS is currently expected to be approved for the Chinese high-definition successor to the Enhanced Versatile Disc.Open source implementations of an AVS video decoder can be found in the OpenAVS project and within the libavcodec library. The latter is integrated in some free video players like MPlayer, VLC or xine. xAVS is also an open source AVS encoder with a working decoder.China's proposed high-definition video disc format, known as CBHD (China Blue High-Definition), will include support for AVS.

MP4 MEDIA FILES

MPEG-4 Part 14, formally ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital audio and digital video streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. A separate hint track is used to include streaming information in the file. The official filename extension for MPEG-4 Part 14 files is .mp4, thus the container format is often referred to simply as MP4.
Some devices advertised as "MP4 players" are simply MP3 players that also play AMV video and/or some other video format, and do not play MPEG-4 part 14 format. This can become rather confusing for potential buyers.it is frequntly used in mobile phones other than mp4(in short)player.It format of vedio make the size of media very short and have good result, therefor used frequntly.

3GP SONG,VIDEOS,ETC

3GP (3GPP file format) is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS multimedia services. It is used on 3G mobile phones but can also be played on some 2G and 4G phones.it is frequently used in many countries for mobile mean celullar phones.it may contain the data of any type.3G2 (3GPP2 file format) is a multimedia container format defined by the 3GPP2 for 3G CDMA2000 multimedia services. It is very similar to 3GP file format.
3GP is defined in ETSI 3GPP technical specification.3GP is required file format for video and associated speech/audio media types and timed text in ETSI 3GPP technical specifications for IP Multimedia Subsystem (IMS), Multimedia Messaging Service (MMS) and Transparent end-to-end Packet-switched Streaming Service (PSS). 3G2 is defined in 3GPP2 technical specification.
