Zencoder
Zencoder is the creator of an open-source HTML5 video player, Video.js, built with Javascript, HTML, and CSS. Video.js plays video via native playback in all HTML5 browsers and devices, or through Adobe Flash when HTML5 playback is not available.
Internet Browser (Nintendo 3DS)
An improved version of the browser is included on the New Nintendo 3DS and New Nintendo 2DS XL consoles, which includes the ability to play HTML5-based videos in both 2D and 3D, courtesy of the system's improved CPU performance. The New Nintendo 3DS and its XL variant can also handle higher video quality thanks to the faster GPU and video decoding chip. The new browser also renders pages much faster.
