#6492: Intel QSV: "No device available for encoder" message is given
-------------------------------------+-------------------------------------

Summary of the bug:
As of ~2017-06-15, attempting to use the h264_qsv encoder will result in a
message that says "'''No device available for encoder (device type qsv f
or codec h264_qsv).'''" The encode still occurs, but this is presumably a
software fallback. Issue was confirmed on an i7-3770 and an i5-4570S.
Tested using Zeranoe Win64 static builds; Build from 2017-06-15 is the
first build that exhibits the issue.
How to reproduce:
{{{
% ffmpeg -f lavfi -i smptebars -c:v h264_qsv -look_ahead 0 -q:v 10 -r
30000/1001 -t 10 -an 360p1.mp4
}}}
