[FFmpeg-devel] [PATCH v5 3/3] avutil/hwcontext_qsv: fix mapping issue between QSV frames and D3D11VA frames

[Tong Wu <tong1.wu-at-intel.com@ffmpeg.org>]

Fixes:
$ ffmpeg.exe -init_hw_device d3d11va=d3d11 -init_hw_device \
qsv=qsv@d3d11 -s:v WxH -pix_fmt nv12 -i input.yuv -vf \
"hwupload=extra_hw_frames=16,hwmap=derive_device=d3d11va,format=d3d11,\
hwmap=derive_device=qsv,format=qsv" -f null -
