[FFmpeg-devel] [PATCH v5 1/3] avutil/hwcontext_qsv: derive QSV frames to D3D11VA frames

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

Fixes:
$ ffmpeg.exe -y -hwaccel qsv -init_hw_device d3d11va=d3d11 \
-init_hw_device qsv=qsv@d3d11 -c:v h264_qsv -i input.h264 \
-vf "hwmap=derive_device=d3d11va,format=d3d11" -f null -
