ffmpeg - CentOS 7.4.1708 : ERROR: x265 not found using pkg-config

Question

我正在尝试按照 https://trac.ffmpeg.org/wiki/CompilationGuide/Centos 上的指南编译具有 Nvidia 支持的 ffmpeg和 https://developer.nvidia.com/ffmpeg .我最终得到了以下命令:
PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --enable-pthreads --disable-w32threads --prefix="$HOME/ffmpeg_build" --pkg-config-flags="--static" --extra-cflags="-I$HOME/ffmpeg_build/include -I/usr/local/cuda/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib -L/usr/local/cuda/lib64" --extra-libs='-lpthread -lm' --bindir="$HOME/bin" --enable-gpl --enable-libfdk_aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree --enable-cuda --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp
我得到了奇妙的错误

ERROR: x265 not found using pkg-config

正在查看 ffbuild/config.log显示以下错误:

gcc 版本是 gcc-4.8.5-16.el7.x86_64

根据以下问题:是的 - x265 是根据 https://trac.ffmpeg.org/wiki/CompilationGuide/Centos 安装的是的 pkg-config 正在找到它。编译错误让我认为我缺少 --pkg-config-flags 选项的标志，但我找不到一个有效的标志。

有谁知道我应该将什么传递给 pkg-config 以使其启用 x265？

Answer 1

万一这对其他人有帮助，我最后发现我不需要提供选项 --enable-libx265当您还指定 --enable-nvenc .

我仍然不知道编译错误是什么，但是 --enable-nvenc您可以使用基于 nVidia 的 GPU 加速在 H.265 中进行编码。
