在amazon linux上安装ffmpeg - cpp,gcc和libstdc ++ dependancies

Question

我对复杂的配置相当新,我试图在amazon linux EC2实例上设置ffmpeg,使用这里的指令...

http://wiki.razuna.com/display/ecp/FFMpeg+Installation+on+CentOS+and+RedHat

...但是当我尝试下面这行时,我碰到了一堵墙......

yum install glibc gcc gcc-c++ autoconf automake libtool

这是我得到的错误......

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

以下是如何使用静态构建在Linux上安装FFMPEG.

SSH进入您的实例并成为root用户

sudo su -

转到/ usr/local/bin目录

cd /usr/local/bin

在/ usr/local/bin目录中,创建一个"ffmpeg"目录

mkdir ffmpeg

进入新目录

cd ffmpeg

现在,打开浏览器并转到http://ffmpeg.gusari.org/static/64bit/上的FFMPEG静态构建列表,然后选择最新版本.在撰写本文时,它是ffmpeg.static.64bit.2014-02-16.tar.gz.

在/ usr/local/bin/ffmpeg目录中,键入以下命令以下载您选择的静态构建

wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-amd64-static.tar.xz

现在,解读它......

tar -xzf ffmpeg-git-amd64-static.tar.xz

运行它并检查最新版本是什么

./ffmpeg -version

输出应该看起来像这样

ffmpeg version N-60675-g8fe1076

libswresample 0. 17.104 / 0. 17.104
libpostproc 52. 3.100 / 52. 3.100

如果您希望能够从任何目录执行FFMPEG,只需在/ usr/bin中创建一个符号链接,如下所示:

ln -s /usr/local/bin/ffmpeg/ffmpeg /usr/bin/ffmpeg

第一部分(/ usr/local/bin/ffmpeg/ffmpeg)是我解压缩文件后文件所在的位置.第二部分(/ usr/bin/ffmpeg)是我们想要符号链接的地方

现在,您应该可以从任何地方运行命令"ffmpeg"
