    • Microsoft Edge has limited VP9 support.  We’ve updated the platform status page to clarify exactly what is supported.  Currently, VP9 is only supported by MSE sources.  The repro page uses a progressive source, which is not supported by Edge.  Also, VP9 playback requires hardware acceleration.  However, you can override the hardware acceleration requirement in about:flags.

      All the best,

    • Can you change your “design” to make WebM videos work properly?

      99% of the WebM videos I encounter on the web can’t be played in Edge but work fine in other browsers.

      I find it very misleading when you say you support WebM and VP9, when in fact you only support it in some theoretical scenarios rarely encountered on the real Web.

      But call me crazy, let’s ask html5test.com what they think about the Edge WebM support:

      WebM with VP8 support
      No ✘
      WebM with VP9 support
      No ✘
      WebM with Vorbis support
      No ✘
      WebM with Opus support
      No ✘

      In other words, 100% fail.

      Either implement WebM and the associated codecs properly, or stop claiming you support them.

      Tested on the Anniversary Update with the Opus and VP9 flags enabled.
