错误:必须安装libfdk_aac

Question

嗨,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 \

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.

我只是按照这个编译指南: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

第一次尝试

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

例

Answer 3

自制ffmpeg

几个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*。这是因为从Homebrew FFmpeg核心公式中删除了选项。

1. 卸载ffmpeg是从Homebrew core安装的：

   brew uninstall ffmpeg
   

2. 启用存储库：

   brew tap homebrew-ffmpeg/ffmpeg
   

3. 查看可用选项（可选）：

   brew options homebrew-ffmpeg/ffmpeg/ffmpeg
   

4. 安装ffmpeg与libfdk-AAC AAC编码器：

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

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