在亚马逊 linux 上安装 ffmpeg - cpp、gcc 和 libstdc++ 依赖项

Question

我对复杂的配置相当陌生，并且正在尝试使用此处的说明在亚马逊 linux EC2 实例上设置 ffmpeg ...

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

...但是我在尝试以下行时遇到了困难...

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

Answer 1

这是使用静态版本在Linux上安装FFMPEG的方法。

一个很好的常见问题解答在这里： https ： //www.johnvansickle.com/ffmpeg/faq/

SSH进入您的实例并成为root

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https://johnvansickle.com/ffmpeg/的FFMPEG静态版本列表，然后选择最新版本。

在/ usr / local / bin / ffmpeg目录中，键入以下命令以下载您选择的静态内部版本

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

现在，解开...

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

运行它并检查最新版本

./ffmpeg -version

输出应如下所示

ffmpeg version N-60675-g8fe1076
built on Feb 16 2014 05:45:47 with gcc 4.6 (Debian 4.6.3-1)
configuration: --prefix=/root/ffmpeg-static/64bit --extra-cflags='-I/root/ffmpeg-

enable-libvo-aacenc --enable-libvo-amrwbenc --enable-version3 --enable-libvpx
libavutil 52. 64.100 / 52. 64.100
libavcodec 55. 52.102 / 55. 52.102
libavformat 55. 32.101 / 55. 32.101
libavdevice 55. 9.101 / 55. 9.101
libavfilter 4. 1.102 / 4. 1.102
libswscale 2. 5.101 / 2. 5.101
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

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

现在，您应该可以从任何地方运行命令“ ffmpeg”

Answer 2

马克的回答对我很有用。 要使用 FFProbe（ffprobe 从多媒体流中收集信息并以人类和机器可读的格式打印出来），您也可以向其中添加 simlink：

ln -snf /usr/local/bin/ffmpeg/ffprobe /usr/bin/ffprobe

Answer 3

您可以从http://ffmpeg.gusari.org/static/64bit下载静态版本。 它可以在64位Amzn Linux上正常运行。
