lavfi: add hwdevice flag to hwupload/hwmap
This fixes a regression introduced by:
commit 3f63685c35
and
commit 632c349931
...where command-lines like:
ffmpeg -v verbose -hwaccel qsv \
-init_hw_device qsv=qsv,child_device=/dev/dri/renderD128 \
-hwaccel_output_format qsv -f rawvideo -pix_fmt yuv420p \
-s:v 352x288 -r:v 25 -i input.yuv \
-vf 'format=nv12,hwupload=extra_hw_frames=120' \
-an -c:v h264_qsv -y output.h264
ffmpeg -v verbose -hwaccel qsv \
-init_hw_device qsv=qsv,child_device=/dev/dri/renderD128 \
-hwaccel_output_format qsv -f rawvideo -pix_fmt nv12 \
-s:v 352x288 -r:v 25 -i input.yuv \
-vf 'format=nv12|qsv,hwupload=extra_hw_frames=16,vpp_qsv=procamp=1:saturation=1.0,hwdownload,format=nv12' \
-pix_fmt nv12 -f rawvideo -fps_mode passthrough -an -y output.yuv
...produced errors like:
[hwupload @ 0x55b6171d0dc0] A hardware device reference is required to upload frames to.
[Parsed_hwupload_1 @ 0x55b6172053c0] Query format failed for 'Parsed_hwupload_1': Invalid argument
