Comment (by Florian Grill):

 Well I already tried that, with overriding the MAX_SLICES in the
 dxva2_h264 file the following command

 {{{
 .\ffmpeg.exe -hwaccel dxva2 -i .\example.h264 test.jpg
 }}}

 And

 {{{
 .\ffmpeg.exe -hwaccel d3d11va -i .\example.h264 test.jpg
 }}}

 both producing the same and correct expected image. Is that what is needed
 to approve that it us working?
