CentOS 7.4.1708:错误:使用 pkg 配置找不到 x265

Question

我正在尝试按照 https://trac.ffmpeg.org/wiki/CompilationGuide/Centos 和 https://developer.nvidia.com/ffmpeg 指南编译 Nvidia 支持的 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

我遇到了一个奇妙的错误

错误：使用 pkg 配置找不到 x265

查看ffbuild/config.log会发现以下错误：

GCC 版本是 GCC-4.8.5-16.el7.x86_64

根据下面的问题：是的 - x265 按照 https://trac.ffmpeg.org/wiki/CompilationGuide/Centos 安装，是的 pkg-config 正在找到它。编译错误让我认为我缺少 --pkg-config-flags optnion 的标志，但我找不到一个有效的标志。

有谁知道我应该传递给 pkg-config 以使其启用 x265？

如果这对其他人有帮助，我最终发现当您也指定--enable-nvenc时，我不需要提供选项--enable-libx265.

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