With VP9 and Opus enabled, the following Media Source Extension capability checks will return true.These are available to websites that use Media Source Extensions (MSE) to adaptively stream video content.This change will be available in stable releases starting with the Windows 10 Anniversary Update.
The VP9 and WebM project team recently joined the Alliance for Open Media effort where their work on VP9 is expected to be a significant contribution to the next generation of open-source, royalty-free video codecs. Opus is the primary audio codec paired with VP9 in the WebM specification. To try them in Microsoft Edge, please install the most recent Windows 10 Insider Build. More recently, we added support within MP4 for H.265HEVC video and Dolby Digital multi-channel audio, formats targeted at high-performance media. VP9 is an open source video codec that has efficient compression well suited to HD and 4K streaming. Opus, similarly, is a very efficient open source audio codec. They are used together by some prominent websites notably YouTube that value them for this efficiency, especially on content with greater than 1080p resolution. Adding WebM, VP9 and Opus to Microsoft Edge means the full experience on these websites will be possible in the Edge browser. Video decoding is computationally complex, so the best experience will be seen on computers that have VP9 hardware acceleration which is optimized for 4K decoding support, a feature which will start to become common on devices later this year. Software decoding can yield good performance, but will work best on more powerful desktop or laptop computers. The elevation is highest on 4K content because the computing load correlates closely with video resolution. Opus Codec For Windows Software Decode ToIf we compare software decode to hardware accelerated decode, software decode may consume 20 more total power when viewing a 1080p video, and up to 80 more power viewing 2160p. The following charts compare hardware video decode to software video decode at different resolutions on a mid-level laptop computer. For this reason, weve put VP9 behind an experimental flag in Microsoft Edge, and have provided a default setting for it that automatically enables VP9 when hardware acceleration is detected. We have, however, elected to put Opus behind an experimental flag as well. We did this for the power reason previously discussed as well as the potential on less powerful computers to experience frame drops when doing software decode on higher resolution streams. The full set of VP9 flag settings and their meaning are. We encourage experimenting with these settings and look forward to your feedback. Its possible to disable Opus using this flag, which would make it unavailable for playback and show as unsupported via isTypeSupported(). The Edge WebRTC implementation supports VP8 and Opus regardless of the flag settings.
