Centos 7 下编译安装FFmpeg 4.1 版本无报错

我在系统中安装了2个版本的python，一个是python 3.6，另一个是centos7 自带的python2.7，我已经把默认python指定为python3，在命令行输入Python2会执行python2.7版本

ffmpeg 4.1 编译安装后，可以得到ffmpeg，ffprobe，ffplay。ffmpeg 4.0 开始删掉了ffserver。

FFmpeg 3.4 编译安装后，可以得到ffmpeg，ffprobe，ffplay，ffserver

下面开始按步骤来

第一步,如果你已经安装了最新版gcc，gcc-c++，cmake，make的话，请忽略安装这些程序！
- yum install autoconf automake bzip2 cmake freetype-devel gcc gcc-c++ git libtool make mercurial pkgconfig zlib-devel harfbuzz-devel
第二步
mkdir ~/ffmpeg_sources

升级开发工具

yum install centos-release-scl -y
yum install devtoolset-7-toolchain -y
scl enable devtoolset-7 bash

CMAKE,安装最新版本(非必须，但推荐)

cd ~/ffmpeg_sources
curl -O -L https://src.fedoraproject.org/lookaside/extras/cmake/cmake-3.13.2.tar.gz/sha512/da095d483326ed379bfc8fa54e95db3426149ab923479a757149a4aed5c90693c0244bc2c9550cf4b64385f5003ee2060fea1698d989ed13bd0198e718c40903/cmake-3.13.2.tar.gz
tar xzvf cmake-3.13.2.tar.gz
cd cmake-3.13.2
./bootstrap --prefix=/usr/local
make
make install

ln -s -f /usr/local/bin/ccmake /usr/bin/
ln -s -f /usr/local/bin/cmake /usr/bin/
ln -s -f /usr/local/bin/ctest /usr/bin/
ln -s -f /usr/local/bin/cpack /usr/bin/

mercurial (hg), 只支持python2.x版本，如果你的系统上安装了多个python版本，且前提条件是在命令行输入python2的时候，执行的是2.x版本的python
- whereis hg 查看hg位置
- vi /usr/bin/hg 进入编辑模式
- 把第一行代码改成如下: #!/usr/bin/python2
- 保存退出
- # hg --version

ffplay使用sdl作为窗体，需要先安装SDL2，如果不需要ffplay可以跳过这个步骤！
