How to Enable or Disable VP9 Code Extension in Microsoft Edge in Windows 10

VP9 is an open source video format that offers efficient compression to stream HD content at lower bitrates, and is well suited to UHD streaming.

The initial VP9 implementation in Microsoft Edge will support adaptive streaming using Media Source Extensions, and will be detectable using the MediaSource.isTypeSupported() API. It will be specifically targeted to meet the needs of websites that use VP9 to deliver video in combination with MP4/AAC or other audio codecs already supported by Microsoft. Microsoft is working on future support for VP9 for media tags and local playback, as well as considering support for additional audio formats likely to be used with VP9 such as Opus.

This implementation of VP9 will support software decoding and, when supported by the device, hardware decoding. Since decoding video is computationally complex, the best experience with the software decoder will be seen on more powerful desktop and laptop computers.

Given this, VP9 will initially be implemented behind an experimental flag in Microsoft Edge as Microsoft continues to work with industry partners on broader support for hardware decoding, and as Microsoft evaluates support for additional audio formats. A setting will be available that alternatively enables or disables VP9 support.

VP9 is now supported in Microsoft Edge starting in Windows 10 Insider Preview build 10547.

This tutorial will show you how to enable or disable the VP9 codec extension in Microsoft Edge for your account in Windows 10.
