如何在 CentOS 7 linux上安装和使用 FFmpeg

wget http://www.ffmpeg.org/releases/ffmpeg-5.1.tar.gz

tar -zxvf ffmpeg-5.1.tar.gz

cd ffmpeg-5.1

./configure --prefix=/usr/local/ffmpeg

./configure --prefix=/usr/local/ffmpeg --enable-openssl --disable-x86asm

make && make install

vi /etc/profile

在最后PATH添加环境变量：

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

yasm/nasm not found or too old. Use –disable-yasm for a crippled build.

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
solve the problem.

wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar -zxvf yasm-1.3.0.tar.gz
cd yasm-1.3.0
./configure
make && make install
