+VP9 is an open and royalty-free video codec that has been supported in Chromium +since 2013. An update adds a new +string format for describing the encoding properties, such as the profile, +level, etc. Such properties are common in video codecs but are not exposed in +the current VP9 string format. +
+
+In addition, this update includes a new format to advertise support for VP9 +Profile 2. This profile is needed to enable higher bit-depth video and the new +binding allows higher granularity in the query for specific features of the VP9 +bitstream. The string format is accepted by media-related APIs such as +MediaSource.isTypeSupported(), HTMLMediaElement.canPlayType(), and
+navigator.requestMediaKeySystemAccess().
