Estou tentando construir o ffmpeg com suporte a NVENC para que eu possa construir o obs-studio com suporte ao NVENC, usando isto como um guia . Eu resolvi todas as dependências depois de um pouco de dor de cabeça, e estou agora a ponto de eu dever ser capaz de compilar o ffmpeg com as edições em seu arquivo de regras muito bem. No entanto, meu terminal confiável me diz o seguinte:

Aqui está o meu arquivo ffmpeg / debian / rules:
#!/usr/bin/make -f
export V=1
# sets DEBIAN_VERSION variable
include /usr/share/dpkg/pkg-info.mk
# Get the Debian version revision:
DEB_REVISION := $(word 2, $(subst -, ,$(DEB_VERSION)))
# sets DEB_HOST_* variables
include /usr/share/dpkg/architecture.mk
# Ubuntu ld adds -Bsymbolic-functions by default, but that prevents FFmpeg from building.
export DEB_LDFLAGS_MAINT_STRIP=-Wl,-Bsymbolic-functions
# Package name for the extra flavor.
EXTRA_PKGS := $(shell sed -nr 's/^Package:[[:space:]]*(.*extra[0-9]+)[[:space:]]*$$//p' debian/control)
FLAVORS = standard extra static
# Enable as many features as possible, as long as the result is still GPLv2+ (a GPLv3+ variant is built as libavcodec-extra/libavfilter-extra flavor).
# The following flags (and build-dependencies) are not added, because they would require a libavformat-extra flavor:
# --enable-libsmbclient (libsmbclient-dev [!hurd-i386 !m68k !sparc64])
# The following flags are not added, because the necessary libraries are not in Debian:
# --enable-decklink
# --enable-libcelt (see #676592: removed from Debian as abandoned upstream, replaced by opus)
# --enable-libdcadec
# --enable-libilbc (see #675959 for the RFP bug)
# --enable-libkvazaar
# --enable-libmfx
# --enable-libnut
# --enable-libopenh264
# --enable-libopenmpt
# --enable-libschroedinger (see #845037: removal due to security issues)
# --enable-libutvideo
# --enable-libvidstab (see #709193 for the RFP bug)
# --enable-libxavs
# --enable-libzimg
# The following flags are not added for various reasons:
# * --enable-librtmp: ffmpeg has better built-in RTMP support with listen mode.
# * --enable-libv4l2 [!hurd-any]: This is only needed for very old devices and may cause problems for others.
# Should anyone need it, using LD_PRELOAD pointing on libv4l2 has the same effect.
# * --enable-opencl [!hurd-any]: This is considered an experimental API.
