错误：必须安装libfdk_aac

Question

您好我正在尝试编译ffmpeg，但此错误显示：

☁  ffmpeg [master] ./configure --enable-gpl --enable-version3 --enable-nonfree \
--enable-postproc --enable-libass \
--enable-libfaac --enable-nonfree --enable-libfdk-aac --enable-libfreetype \
--enable-libmp3lame --enable-libopencore-amrnb \
--enable-libopencore-amrwb --enable-libopenjpeg \
--enable-openssl --enable-libschroedinger --enable-libtheora \
--enable-libvo-aacenc --enable-libvorbis --enable-libvpx \

ERROR: libfdk_aac must be installed and version must be >= 3.4.12.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

我只是遵循这个编译指南：https://trac.ffmpeg.org/wiki/MacOSXCompilationGuide

Answer 1

您可以使用该编码库安装ffmpeg，如下所示：

brew install ffmpeg --with-fdk-aac

Answer 2

首先尝试

brew install fdk-aac

如果没有你可以像我一样编译

git clone git://github.com/mstorsjo/fdk-aac
cd fdk-aac
autoreconf -i
./configure
make install

Example

Answer 3

homebrew-ffmpeg

一些FFmpeg贡献者和社区成员创建了一个新的Homebrew水龙头，其中包括许多选项*。这是对删除Homebrew FFmpeg核心公式中的选项的反应。

1. 卸载ffmpeg是从Homebrew核心安装的：

   brew uninstall ffmpeg
   

2. 启用存储库：

   brew tap varenc/ffmpeg
   

3. 查看可用选项（可选）：

   brew options varenc/ffmpeg/ffmpeg
   

4. 使用libfdk-aac AAC编码器安装ffmpeg：

   brew install varenc/ffmpeg/ffmpeg --with-fdk-aac --HEAD
   

有关更多信息，请参见varenc/homebrew-ffmpeg和FFmpeg Wiki: macOS。
