解决最近的安装失败ffmpeg,记录下,防止下次出现问题

1、下载解压

    wget http://www.ffmpeg.org/releases/ffmpeg-7.0.tar.gz
    tar -zxvf ffmpeg-7.0.tar.gz

2、 进入解压后目录,输入如下命令/usr/local/ffmpeg为自己指定的安装目录

cd ffmpeg-7.0
./configure --prefix=/usr/local/ffmpeg
make && make install

安装过程中如出现以下报错,则需要安装yasm包(没有就跳过,有问题请跳转下面的)

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.

没问题跳过。

3、配置变量

vim /etc/profile

在最后PATH添加环境变量:

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

保存退出 按ESC,然后输入:wq 查看是否生效

source /etc/profile

4、查看安装版本

ffmpeg -version

注意事项: 安装过程中如出现以下报错,则需要安装yasm包 安装yasm:

   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

安装好后,重新执行 ffmpeg的安装即可
