ffmpeg 编译错误 nasm/yasm not found or too old
问题描述
在 Linux/Unix 中，使用源码编译 ffmpeg。运行以下命令。
$ git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
$ cd ffmpeg
$ ./configure --prefix=/opt/ffmpeg
nasm/yasm not found or too old. Use --disable-x86asm 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 "ffbuild/config.log" produced by configure as this will help
solve the problem.解决方法
需要安装 nasm 或者 yasm。
Mac OS
brew install nasmUbuntu/Debian
安装 nasm。
sudo apt install nasm安装 yasm。
sudo apt install yasmRHEL/CentOS
安装 nasm。
sudo yum install nasm或者前往 https://pkgs.org/search/?q=yasm，下载与操作系统相对应的 yasm，比如 x86_64 的 centos 8：
$ wget http://mirror.centos.org/centos/8/PowerTools/x86_64/os/Packages/yasm-1.3.0-7.el8.x86_64.rpm
$ sudo yum install ./yasm-1.3.0-7.el8.x86_64.rpm
