Got it, thanks. Please find the patches in attachment. Just for my own understanding - could you please explain how this magic works in the configure script? I mean this section:
if ! disabled ffnvcodec; then
ffnv_hdr_list="ffnvcodec/nvEncodeAPI.h ffnvcodec/dynlink_cuda.h
ffnvcodec/dynlink_cuviddec.h ffnvcodec/dynlink_nvcuvid.h"
check_pkg_config ffnvcodec "ffnvcodec >= 12.1.14.0" "$ffnv_hdr_list" ""
|| \
check_pkg_config ffnvcodec "ffnvcodec >= 12.0.16.0 ffnvcodec < 12.1"
"$ffnv_hdr_list" "" || \
check_pkg_config ffnvcodec "ffnvcodec >= 11.1.5.2 ffnvcodec < 12.0"
"$ffnv_hdr_list" "" || \
check_pkg_config ffnvcodec "ffnvcodec >= 11.0.10.2 ffnvcodec < 11.1"
"$ffnv_hdr_list" "" || \
check_pkg_config ffnvcodec "ffnvcodec >= 8.1.24.14 ffnvcodec < 8.2"
"$ffnv_hdr_list" ""
fi
To me it looks like any ffnvcodec package of version in range between
8.1.24.14 and 12.1.14.0 will pass this check.
