The ffmpeg application does not support DXVA2.
Other players like VLC should however be fine, if build with a proper
toolchain which includes the DXVA2 headers required (say mingw-w64)

If the toolchain provides dxva2 headers, no config flags should be required
and support enabled automatically in avcodec.

Note that Hi10p is not supported by hardware decoders.
