Red Hat （Centos7）下安装最新 FFmpeg

Red Hat （Centos7）下安装最新 ffmpeg

FFmpeg既是一款音视频编解码工具，同时也是一组音视频编解码开发套件，作为编解码开发套件，它为开发者提供了丰富的音视频处理的调用接口。
FFmpeg提供了多种媒体格式的封装和解封装，包括多种音视频编码、多种协议的流媒体、多种色彩格式的转换、多种采样率的转换、多种码率转换等；FFmpeg框架提供了多种丰富的插件模块，包含封装与解封装的插件、编码与解码的插件等。

[root@ip-172-31-32-39 ec2-user]# cat /etc/redhat-release
Red Hat Enterprise Linux release 8.3 (Ootpa)

1、Red Hat 下安装最新 ffmpeg

wget http://www.ffmpeg.org/releases/ffmpeg-4.3.2.tar.gz
tar -zxvf ffmpeg-4.3.2.tar.gz
cd ffmpeg-4.3.2
[root@ip-172-31-32-39 ffmpeg-4.3.2]# ./configure --prefix=/usr/local/ffmpeg
gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.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 "ffbuild/config.log" produced by configure as this will help
solve the problem.

报错缺少gcc，安装一下

yum install gcc*

装完之后再执行编译前检查：

意料之中出现未安装 yasm 汇编编译器的报错

[root@ip-172-31-32-39 ffmpeg-4.3.2]# ./configure --prefix=/usr/local/ffmpeg
nasm/yasm not found or too old. Use --disable-x86asm 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 "ffbuild/config.log" produced by configure as this will help
solve the problem.

2、安装 yasm 汇编编译器
yasm

wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar xzf yasm-1.3.0.tar.gz
cd yasm-1.3.0
./configure --prefix=/usr/local/
make
make install
cd /usr/local/bin/
[root@ip-172-31-32-39 bin]# ./yasm --version
yasm 1.3.0
Compiled on Sep  2 2021.

Run yasm --license for licensing overview and summary.

3、加环境配置文件后再次编译ffmpeg

# tail -3 /etc/profile
##
export PATH=/usr/local/bin:$PATH

# source /etc/profile

#验证yasm命令

[root@ip-172-31-32-39 ffmpeg-4.3.2]# yasm
yasm: No input files specified

#重新编译

./configure --prefix=/usr/local/ffmpeg
make
make install

#验证ffmpeg

# cd /usr/local/
# ls
bin  etc  ffmpeg  games  include  lib  lib64  libexec  sbin  share  src
# cd ffmpeg/
# ls
bin  include  lib  share
# cd bin/
# ls

[root@ip-172-31-32-39 bin]# ./ffmpeg -version

4、拓展
上面只是简单的安装，FFmpeg本身支持一些音视频编码格式、文件封装格式与流媒体传输协议，但是支持的数量有限，FFmpeg所做的只是提供一套基础的框架，所有的编码格式、文件封装格式与流媒体协议均可以作为FFmpeg的一个模块挂载在FFmpeg框架中。这些模块以第三方的外部库的方式提供支持，可以通过FFmpeg源码的configure命令查看FFmpeg所支持的音视频编码格式、文件封装格式与流媒体传输协议，对于FFmpeg不支持的格式，可以通过configure --help查看的第三方外部库，然后通过增加对应的编译参数选项进行支持。

例如需要自己配置FFmpeg支持哪些格式，比如仅支持H.264视频与AAC音频编码，可以调整配置项将其简化如下:

./configure --enable-libx264 --enable-libfdk-aac --enable-gpl --enable-nonfree --prefix=/usr/local/ffmpeg

报错：

ERROR: libfdk_aac not foundIf 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 "ffbuild/config.log" produced by configure as this will help
solve the problem.

fdk-acc下载

wget https://sourceforge.net/projects/opencore-amr/files/fdk-aac/fdk-aac-2.0.2.tar.gz

tar xzf  fdk-aac-2.0.2.tar.gz
cd fdk-aac-2.0.2
./configure  --prefix=/usr/local/
make
make install

再次编译检查./configure --enable-libx264 --enable-libfdk-aac --enable-gpl --enable-nonfree --prefix=/usr/local/ffmpeg
报错：

ERROR: libx264 not foundIf 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 "ffbuild/config.log" produced by configure as this will help
solve the problem.

libx264 下载：

# https://code.videolan.org/videolan/x264/-/tree/stable# 其他版本
# https://ftp.videolan.org/pub/x264/snapshots/
#git clone https://code.videolan.org/videolan/x264.gitwget http://download.videolan.org/pub/videolan/x264/snapshots/x264-snapshot-20191217-2245-stable.tar.bz2

tar xjf x264-snapshot-20191217-2245-stable.tar.bz2
cd x264-snapshot-20191217-2245-stable
./configure --prefix=/usr/local --enable-shared --enable-static --disable-asm
make
make install

vim /etc/profile //文件末尾加入下面内容

export PATH=/usr/local/x264/bin:$PATH
export PATH=/usr/local/x264/include:$PATH
export PATH=/usr/local/x264/lib:$PATH

vim /etc/ld.so.conf //增加以下内容
/usr/local/x264/lib //添加x264库路径，添加完保存退出

# ldconfig //使配置生效

vim /etc/ld.so.conf //增加以下内容
/usr/local/ffmpeg/lib //添加ffmpeg库路径，添加完保存退出
ldconfig //使配置生效

使用方法：在./configure之前输入
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH //(此路径为.pc文件所在路径)，可使用
echo $PKG_CONFIG_PATH //查看有没设置生效

再次执行编译检查

./configure --enable-libx264 --enable-libfdk-aac --enable-gpl --enable-nonfree --prefix=/usr/local/ffmpeg
make
make install

验证

[root@ip-172-31-32-39 bin]# ./ffmpeg --version
./ffmpeg: error while loading shared libraries: libfdk-aac.so.2: cannot open shared object file: No such file or directory

报错了，但是这个文件是有的

[root@ip-172-31-32-39 bin]# find / -name libfdk-aac.so*
/usr/local/lib/libfdk-aac.so.2.0.2

/data/fdk-aac-2.0.2/.libs/libfdk-aac.so.2
/data/fdk-aac-2.0.2/.libs/libfdk-aac.so

在/etc/profile添加一行，整体如下（包含上面添加的）
##
export PATH=/usr/local/bin:$PATH
export PATH=/usr/local/lib/:$PATH
export PATH=/usr/local/x264/bin:$PATH

source /etc/profile

在/etc/ld.so.conf添加一行，整体如下（包含上面添加的）

vim /etc/ld.so.conf
include ld.so.conf.d/*.conf
