Just some more info this is the DXVA GPU accelerated decoder http://imgur.com/a/9MPsphttp://imgur.com/a/q8SfN It basically decodes a VP9 stream with a shader and outputs it into an image format inluding NV12 which means you can use PureVideo for direct ouput.
This one can work with either a dedicated media player or with Edge, Chrome does it's own thing and I'm not entirely sure what they do and I have no clue about Safari/Opera/Firefox so if some one wants to fill in about them that would be nifty.
Whilst technically DXVA is a software decoder https://en.wikipedia.org/wiki/DirectX_Video_Acceleration It does offload the heavy lifting to the GPU via shaders, so can still some what classify it as "hardware decoding" since softare decoder/encoders are usually defined as CPU only.
