Imagine ultra low bandwidth HEVC/H.265 video streaming to your Linux laptop, your Android device, Chrome browser, Firefox. On Mac OS, Windows and the iPhone. A dream? Not anymore!
The libde265 team presents a demo of libde265.js, a JavaScript version of the libde265 H.265 High Efficiency Video decoder.
The lib265.js HEVC/H.265 bitstream decoder entirely runs in JavaScript. Various browsers have been tested including Chrome and Firefox on Android, Linux and Windows, Safari 7 on OSX Mavericks, IE11 and Opera 20 on Windows.
libde265.js demo and source code is available on http://strukturag.github.io/libde265.js/
The HTML code from the demo can be used as an example on how to integrate libde265.js on a website:
https://github.com/strukturag/libde265.js/blob/gh-pages/index.html
Please note that the HEVC/H.265 bitstream file (here “spreedmovie.hevc”) must be located on the same server that provides the HTML as the HEVC movie file can’t be loaded cross-domain.
Playback speed on a fast PC is about: ~46 fps in Firefox, ~40 fps in Chrome. A Nexus 5 plays around 11fps.

July 6thOn Chrome OS 37.xxx. (dev channel), using ARM Samsung 3 Chromebook, I have 12 to 14,5 fps but with no sound on this demo. In your app from the Chrome store I tried an 720p/H.264 mkv file with AC3 audio, of a rather high bitrate, where for the first time I have audio but the video playback is very choppy. A message “Your computer is too slow to decode the movie in real time, playback performance may suffer” is displayed. With the latest Subtitle Videoplayer(v.1.7.0) I do not have sound in this copy but the video playback is fine. I then used another 720p/mkv/H.264 copy of a lower bitrate, with AAC audio, and the playback of both video and audio is fine using your H.265 / HEVC player app. Apparently you do not fully support Chrome OS and/or ARM CPUs. I will try to find a lower bitrate mkv/AC3 combo to see if the playback is OK. Thanks a lot for the effort, I hope i will soon be able to enjoy AC3 movies in my Chromebook.
