JW球员 Updates HTML5 Video Report, Finds Broad H.264年支持
The Apple iPad was released five years ago, and video player company JW球员 chose the occasion to update its HTML5视频现状 报告. The iPad wasn't just a breakthrough for the tablet computer market, 但是对于HTML5视频, 也, since its lack of Flash support made HTML5 video more important to publishers.
The 报告 notes that all browsers have supported HTML5 video for a few years now. Early on, some browsers supported the H.264 video codec and others the VP8/WebM codec, but that was resolved when Firefox added H.264年支持. "H.264 can now be played everywhere,报告说, but publishers will need a Flash fallback for Opera and Internet Explorer 8 users.
Not all browsers offer the same HTML5 Video features, however. The 报告 shows which browsers support full-screen video playback, and which do so with built-in support or with the W3C full-screen API.
The 报告 also shows browser support for WebVTT closed captioning, 样式, 和脚本, 也 as support for Media Source Extensions and Encrypted Media Extensions. "Several browsers support these APIs, but severe limitations still exist," the 报告 notes. The full 报告 is available online with no registration required. JW球员 updates it regularly to show changes in support.
