问题汇总

问题1：libass相关

报错内容：ERROR: libass >= 0.11.0 not found using pkg-config

解决方案：

sudo yum install libass-devel

问题2：opus

报错内容：ERROR: opus not found using pkg-config

解决方案：

sudo yum install opus opus-devel

问题3：vorbis

报错内容：ERROR: vorbis not found using pkg-config

解决方案：

sudo yum install libvorbis-devel

问题4：libvorbis

报错内容：ERROR: vorbis not found using pkg-config

解决方案：

# 下载源码方式1(可能会失败)
git clone https://github.com/xiph/vorbis.git
cd vorbis

#下载源码方式2
wget https://downloads.xiph.org/releases/vorbis/libvorbis-1.3.7.tar.gz
tar -xzf libvorbis-1.3.7.tar.gz
cd libvorbis-1.3.7

# 解压、配置、编译和安装
./autogen.sh  # 可能需要
./configure --prefix=/usr/local --enable-shared
make -j$(nproc)
sudo make install

编译并安装

make -j$(nproc)
sudo make install

动态库拷贝

将上述/usr/local/lib/下编译好的动态库拷贝至/usr/local/ffmpeg/lib。

环境变量配置

export PATH=/usr/local/ffmpeg/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/ffmpeg/lib:$LD_LIBRARY_PATH

查看版本

ffmpeg -version
