ffmpeg升级和转移
下载编译安装
到 Ffmpeg 官网 https://ffmpeg.org/download.html 挑选你要升级到的版本
tar -zxvf FFmpeg-n4.4.tar.gz
cd FFmpeg-n4.4
./configure --enable-shared --prefix=/usr/local/ffmpeg
make -j2 && make install
动态链接库
cat >> /etc/ld.so.conf << 'EOF'
/usr/local/ffmpeg/lib
EOF
# 执行
ldconfig
设置环境变量
cat > /etc/profile.d/ffm.sh << 'EOF'
export FFM_HOME=/usr/local/ffmpeg
export PATH=$FFM_HOME/bin:$PATH
EOF
source /etc/profile
执行ffmpeg -version
[root@localhost ~]# ffmpeg -version
