在Amazon Linux上安装ffmpeg-cpp，gcc和libstdc ++依赖关系 [英] Installing ffmpeg on amazon linux - cpp, gcc & libstdc++ dependancies

问题描述

对于复杂的配置我还是很陌生，&我正在尝试使用此处的说明在亚马逊Linux EC2实例上设置ffmpeg ...

I'm fairly new to complicated config, & am trying to setup ffmpeg on an amazon linux EC2 instance, using the instruction here...

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

...但是尝试以下一行时，我碰到了墙...

... however I've hit a wall when trying the following line...

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

这是我遇到的错误...

Here's the errors I'm getting...

Package matching autoconf-2.59-12.noarch already installed. Checking for update.

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

推荐答案

此处介绍如何使用静态版本在Linux上安装FFMPEG.

Here is how to install FFMPEG on Linux using a static build.

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

A good FAQ is here: https://www.johnvansickle.com/ffmpeg/faq/

SSH进入您的实例并成为root

SSH into your instance and become root

sudo su -

转到/usr/local/bin目录

Go to the the /usr/local/bin directory

cd /usr/local/bin

在/usr/local/bin目录中，创建一个"ffmpeg"目录

Inside the /usr/local/bin directory, create an "ffmpeg" directory

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.

Now, open a browser and go to the list of FFMPEG static builds at https://johnvansickle.com/ffmpeg/ and pick the latest version.

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

While inside the /usr/local/bin/ffmpeg directory, type the following command to download the static build you have selected

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-

extra-libs='-lxml2 -lexpat -lfreetype' --enable-static --disable-shared --disable-ffserver --

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:

If you want to be able to execute FFMPEG from any directory, simply create a symlink into /usr/bin like this:

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

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

The first part (/usr/local/bin/ffmpeg/ffmpeg) is where the file is located after I untarred the file. The second part (/usr/bin/ffmpeg) is where we want the symlink to go

现在，您应该可以在任何地方运行命令"ffmpeg"

Now, you should be able to run the command "ffmpeg" from anywhere
