[FFmpeg-devel] [PATCH] libavcodec/qsvenc_hevc: correction for QSV HEVC default plugin selection on Windows

[Landgraph]

1. Old logic meaned: everywhere, except Windows, ffmpeg has to use HW 
acceleration, but on Windows ffmpeg has to use (unavailable) software 
encode by default
2. Software encode is available only if you provide corresponding 
software MediaSDK library, which isn't provided with ffmpeg. More 
information could be found in 
https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/samples/readme-encode_linux.pdf
3. HW encode is available on Windows in the driver by default
