MPEG logo Some well known older (up to 2005) digital media formats and the MPEG standards they use. The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by ISO and IEC that sets standards for media coding, including compression coding of audio, video, graphics, and genomic data; and transmission and file formats for various applications.

VVenC & VVdeC – An open-source encoder and decoder released by Fraunhofer HHI based on the Versatile Video Coding (VVC/H.266) standard available on GitHub. XEVE (the eXtra-fast Essential Video Encoder) MPEG-5 Part 1: Essential Video Coding; XEVD (the eXtra-fast Essential Video Decoder) MPEG-5 Part 1: Essential Video Coding
MPEG-21 defines also a "Rights Expression Language" standard as means of managing restrictions for digital content usage.As an XML-based standard, MPEG-21 is designed to communicate machine-readable license information and do so in a "ubiquitous, unambiguous and secure" manner.
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 ...
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
libmpeg2 is a free and open source software library for decoding MPEG-1 and MPEG-2 video streams. libmpeg2 is released under the terms of the GNU GPL license. Legality and software patents [ edit ]
In the newer designs found in H.264/MPEG-4 AVC and HEVC, encoders have much more flexibility about referencing structures. They can use the same referencing structures as were previously used in older designs, or they can use more pictures as references and they can use more flexible ordering of the coding order relative to the display order.
MPEG-2 is used in Digital Video Broadcast and DVDs. The MPEG transport stream, TS, and MPEG program stream, PS, are container formats.. MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". [1]
