VP9
VP9 is an open and royalty-free video coding format developed by Google. VP9 is the successor to VP8 and competes mainly with MPEG's High Efficiency Video Coding (HEVC/H.265). At first, VP9 was mainly used on Google's video platform YouTube. The emergence of the Alliance for Open Media, and its support for the ongoing development of the successor AV1, of which Google is a part, led to growing interest in the format. In contrast to HEVC, VP9 support is common among modern web browsers (see HTML5 video § Browser support). Android has supported VP9 since version 4.4 KitKat, while iOS/iPadOS added support for VP9 in iOS/iPadOS 14. Parts of the format are covered by patents held by Google. The company grants free usage of its own related patents based on reciprocity, i.e. as long as the user does not engage in patent litigations. History VP9 is the last official iteration of the TrueMotion series of video formats that Google bought in 2010 for $134 million together with ...

High Efficiency Video Coding
High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video coding format, video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H.264, or MPEG-4 Part 10). In comparison to AVC, HEVC offers from 25% to 50% better data compression at the same level of video quality, or substantially improved video quality at the same bit rate. It supports resolutions up to 8192×4320, including Ultra-high-definition television, 8K UHD, and unlike the primarily 8-bit AVC, HEVC's higher fidelity Main 10 profile has been incorporated into nearly all supporting hardware. While AVC uses the integer discrete cosine transform (DCT) with 4×4 and 8×8 block sizes, HEVC uses integer DCT and Discrete sine transform, DST transforms with varied block sizes between 4×4 and 32×32. The High Efficiency Image File Format, High Efficiency Image Format (HEIF) is based on HEVC. , HEVC is used by 43% of video develope ...

HTML5 Video
The HTML5 specification introduced the video element for the purpose of playing videos, partially replacing the object element. HTML5 video is intended by its creators to become the new standard way to show video on the web, instead of the previous de facto standard of using the proprietary Adobe Flash plugin, though early adoption was hampered by lack of agreement as to which video coding formats and audio coding formats should be supported in web browsers. As of 2020, HTML5 video is the only widely supported video playback technology in modern browsers, with the Flash plugin being phased out. History of <video> element The <video> element started being discussed by the WHATWG in October 2006. The <video> element was proposed by Opera Software in February 2007. Opera also released a preview build that was showcased the same day, and a manifesto that called for video to become a first-class citizen of the web. <video> element examples The following HTML ...

WebM
WebM is an audiovisual media file format. It is primarily intended to offer a royalty-free alternative to use in the HTML5 video and the HTML5 audio elements. It has a sister project, WebP, for images. The development of the format is sponsored by Google, and the corresponding software is distributed under a BSD license. The WebM container is based on a profile of Matroska. WebM initially supported VP8 video and Vorbis audio streams. In 2013, it was updated to accommodate VP9 video and Opus audio. It also supports the new AV1 codec. Vendor support Software Native WebM support by Mozilla Firefox, Opera, and Google Chrome was announced at the 2010 Google I/O conference. Internet Explorer 9 requires third-party WebM software. In 2021, Apple released Safari 14.1 for macOS, which added native WebM support to the browser. , QuickTime does not natively support WebM, but does with a suitable third-party plug-in. In 2011, the Google WebM Project Team released plugins for Inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FFmpeg
FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the command-line ffmpeg tool itself, designed for processing of video and audio files. It is widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post-production effects and standards compliance (SMPTE, ITU). FFmpeg also includes other tools: ffplay, a simple media player and ffprobe, a command-line tool to display media information. Among included libraries are libavcodec, an audio/video codec library used by many commercial and free software products, libavformat (Lavf), an audio/video container mux and demux library, and libavfilter, a library for enhancing and editing filters through a Gstreamer-like filtergraph. FFmpeg is part of the workflow of many other software projects, and its libraries are a core part of software media players such as VLC, an ...

Video Coding Format
A video coding format (or sometimes video compression format) is a content representation format for storage or transmission of digital video content (such as in a data file or bitstream). It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation. A specific software, firmware, or hardware implementation capable of compression or decompression to/from a specific video coding format is called a video codec. Some video coding formats are documented by a detailed technical specification document known as a video coding specification. Some such specifications are written and approved by standardization organizations as technical standards, and are thus known as a video coding standard. The term 'standard' is also sometimes used for ''de facto'' standards as well as formal standards. Video content encoded using a particular video coding format is normally bundled with an audio stream (encoded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MPEG LA
MPEG LA is an American company based in Denver, Colorado that licenses patent pools covering essential patents required for use of the MPEG-2, MPEG-4, IEEE 1394, VC-1, ATSC, MVC, MPEG-2 Systems, AVC/H.264 and HEVC standards. History MPEG LA started operations in July 1997 immediately after receiving a Department of Justice Business Review Letter. During formation of the MPEG-2 standard, a working group of companies that participated in the formation of the MPEG-2 standard recognized that the biggest challenge to adoption was efficient access to essential patents owned by many patent owners. That ultimately led to a group of various MPEG-2 patent owners to form MPEG LA, which in turn created the first modern-day patent pool as a solution. The majority of patents underlying MPEG-2 technology were owned by three companies: Sony (311 patents), Thomson (198 patents) and Mitsubishi Electric (119 patents). In June 2012, MPEG LA announced a call for patents essential to the High Ef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
