MPEG議長Leonardo Chiariglione氏のブログ記事によると、2020年6月現在の権利者は45企業・団体に急増しており、うち2/3は3つの特許プールいずれかに所属するが、残り1/3はいずれにも属さないという分布状況です。日本でもBS4K/8K実用放送が開始されたように放送業界ではH.265/HEVCコーデック利用が本格化し始めましたが、ストリーミングや双方向Web会議など動画像コーデック需要が急騰しているWeb業界での利用はわずか12%程度に留まるため、MPEG系コーデックのプレゼンス低下は避けられないと予測しています。 MPEG動画像コーデックの歴史を振り返ると、特許問題はそれぞれの商業的成否に強い影響を与えてきました。 MPEG-2 Videoコーデックは2020年現在の日本でもテレビ放送に使われ続けており、明らかな成功モデルとなっています。ちなみにMPEG-2 Vid
Andreas Gal Entrepreneur. Technologist. Former CTO Mozilla, CEO Silk Labs. Now WebRTC is one of the most exciting things to happen to the Web in years: it has the potential to bring instant voice and video calling to anyone with a browser, finally unshackling us from proprietary plugins and installed apps. Firefox, Chrome, and Opera already support WebRTC, and Microsoft recently announced future
Google and the MPEG LA patent licensing company have come to an agreement regarding patents related to the VP8 codec, the core component of Google's WebM video technology. Google has licensed techniques that "may be essential to VP8 and earlier generation VPx video compression technologies," which were apparently covered by patents held by 11 patent holders. The deal enables Google to sub-license
Ouch. So people are mad because they have to pay to make and distribute videos for commercial use? Yes, but it's not as bad as it seems. First off, we've directly asked MPEG-LA whether or not using an H.264 camera simply to shoot video for a commercial purpose requires a license, and the answer is no. We've also asked whether an end user watching H.264 videos would ever have to pay or be licensed,
WebM video plays directly in your web browser using HTML5. No plug-ins are needed, but you must install a modern web browser that supports HTML5 and WebM. What's Great About WebM Very high quality video Great video playback performance, even on older computers 100% free and open to everyone Supported on popular video sites like YouTube Supported Web Browsers Mozilla Firefox 4 and later Opera 10.60
Andreas Gal Entrepreneur. Technologist. Former CTO Mozilla, CEO Silk Labs. Now The Web is an open ecosystem, generally free of proprietary control and technologies—except for video. Today in collaboration with Cisco we are shipping support for H.264 in our WebRTC implementation. Mozilla has always been an advocate for an open Web without proprietary controls and technologies. Unfortunately, no r

Matroska/WebM in MPEG DASH This document defines how to use Matroska/WebM with the MPEG DASH adaptive streaming system defined in ISO-IEC_23009-1 [DASH]. Matroska and WebM share the same file structure, Matroska having some extra features. WebM is also restricted to the VP8 video codec and Vorbis audio codec. The Matroska specification can be found at http://www.matroska.org/technical/specs/index.
