Is an Microsoft Edge(C) extension which allows users to actually use the already present support for h265/hevc. Microsoft Edge(C) already has builtin support for hevc but doesn't report it to websites which in turn results in hevc videos not being played. Especially with webbased mediacenters such as plex or emby this will lead to unnecesary transcoding.
