NationMaster - Encyclopedia: Ogg Media

Ogg Media (OGM), meaning Ogg Media File, is a container format (for video, audio and subtitle streams). It was developed by Tobias Waldvogel and can do a few things the common AVI format cannot. OGM's features include in particular: Ogg is an open standard for a free container format for digital multimedia, unrestricted by software patents and designed for efficient streaming and manipulation. ... A container format is a computer file format that can contain various types of data, compressed by means of standardized codecs. ... It has been suggested that this article or section be merged with Closed captioning. ... AVI, an acronym for Audio Video Interleave, is a multimedia container format introduced by Microsoft in November 1992, as part of the Video for Windows technology. ...

OGM support for Windows (Including Microsoft's Windows Media Player) is available via Tobias's own OggDS, Haali Media Splitter, VLC, or RadLight's Ogg Media filters (the last of which can also decode Theora video). On Unix-based systems OGM support is available in MPlayer, xine and VLC. For other uses, see MP3 (disambiguation). ...

Fundamentally, the format is a hack of the Ogg container format, which had only been designed to support encoders endorsed by Xiph.org (website), the creators of Ogg. It is most likely going to be viewed as a temporary solution, to be phased out when other media container formats (for example, Matroska) mature and come to support the same services.^{[citation needed]} Hack has several meanings in the technology and computer science fields: a clever or quick fix to a computer program problem; a clumsy or inelegant solution to a problem; illegally breaking into a computer, generally over a network connection; or a modification of a program or device to give the...

The Xiph. ... // The Matroska Multimedia Container is an open standard free multimedia container format that can hold an unlimited number of video, audio, picture or subtitle tracks inside a single file. ...

Originally, a major drawback of OGM was that it was not free software / open source, even though it was based on the open-source Ogg framework. The reason was that Tobias was embarrassed about the quick-dirty-hack quality of his code, wanting to improve it before releasing it to the keen eyes of the Xiph.org people ^{[citation needed]}. Tobias has officially joined the Xiph.org team since, and has donated all the code of his DirectShow filters — including format manipulation and playback — to their BSD-style free software licensed repository. It is available, though without documentation, in the "oggds" module of the repository. Another implementation is available in Moritz Bunkus' ogmtools package. This article is about free software as used in the sociopolitical free software movement; for non-free software distributed without charge, see freeware. ... Open source software is computer software whose source code is available under a license (or arrangement such as the public domain) that permits users to study, change, and improve the software, and to redistribute it in modified or unmodified form. ... BSD redirects here; for other uses see BSD (disambiguation). ... This article is about Free Software as defined by the sociopolitical Free Software movement; for information on software distributed without charge, see freeware. ...

OGM files most often carry video encoded in the MPEG-4 ASP format and audio in Vorbis or AC-3 (Dolby Digital).^{[citation needed]} MPEG-4 Part 2 is a video compression technology developed by MPEG. It belongs to the MPEG-4 ISO/IEC standard (ISO/IEC 14496-2). ... Dolby Digital is the marketing name for a series of lossy audio compression technologies by Dolby Laboratories. ...
