What Is VP9?
This is another installment in our series of What Is.? articles, designed to offer definitions, history, and context around significant terms and issues in the online video industry.
VP9 is an open-source codec from Google that was developed from technology acquired from On2 Technologies in February 2010 for an estimated $124.6 million. The first codec Google released from this acquisition was VP8, which was paired with the Vorbis audio codec in the WebM file structure. VP9 is the next iteration of the codec, which became available on June 17, 2013. VP9 will be the last VPx-based codec released by Google, as the company contributed all codec technology to the Alliance for Open Media in September 2015.

Executive Summary
Streaming media production starts with the infinite real world as captured by the lenses of our camcorders, and ends with the tightly compressed files necessary for streaming delivery. Along the way, the video is digitized, encoded, re-encoded, and frequently transcoded, with possible stops along the way for transrating, transsizing, and transmuxing.
These are terms we use every day, but few, if any, have precise definitions. Until now. Read on for our attempt to bring clarity to the lexicon of streaming media workflows and processes as we follow the life of a video from capture to consumption (on multiple platforms, of course).
What Is AV1?
This is another installment in our series of What Is.? articles, designed to offer definitions, history, and context around significant terms and issues in the online video industry.
The AV1 codec will be the first codec released by the Alliance for Open Media (AOM), and it s scheduled to ship sometime between December 2016 and March 2017. It is positioned to replace Google s VP9 and to compete with the standards-based High Efficiency Video Codec (HEVC). While the codec s performance won t be known until it ships, one significant competitive advantage is the Alliance membership, which ensures the prompt deployment of AV1 playback in browsers, mobile devices, OTT, and smart TVs and the distribution of AV1-encoded content by YouTube, Netflix, and Amazon. HEVC enjoys a multiple year lead in hardware-based deployments, however, and some pundits question whether AV1 was created without infringing upon patents owned by H.264, HEVC, and other video-relat
Executive Summary
HTML5 rocketed to the forefront with Apple’s decision to forgo Flash and use HTML5 technology to deliver video to the iPad. Actual HTML5 usage, however, has been slowed by low HTML5-compatible browser penetration, the need to encode video into two or three formats for complete HTML5 compatibility, and the lack of feature parity with Flash, the predominant plug-in based technology for viewing video on the web.
HTML5 needs to be on the radar screen of all streaming media producers, but switching over to HTML5 does not appear to be a short-term priority as of this writing.
