三、安装x264
下载x264
通过git:
git clone https://code.videolan.org/videolan/x264.git
(或)访问官网:
https://www.videolan.org/developers/x264.html
安装
cd x264/
./configure --enable-shared --enable-static
make && sudo make install验证是否已安装
[root@x x264]# x264 --version
x264 0.164.3095 baee400
built on Aug 30 2022, gcc: 4.8.5 20150623 (Red Hat 4.8.5-44)
x264 configuration: --chroma-format=all
libx264 configuration: --chroma-format=all
x264 license: GPL version 2 or later
四、安装pkg
先检查是否已安装pkg，已安装可跳过，(编译ffmpeg错误：ERROR: x264 not found using pkg-config ---重装pkg
pkg安装出现这种报错：
configure: error: pkg-config and "glib-2.0 >= 2.16" not found, please set GLIB_CFLAGS and GLIB_LIBS to the correct values or pass --with-internal-glib to configure
使用 ./configure --with-internal-glib
)
[root@x home]# pkg-config --version
0.27.1
下载pkg软件包
wet https://pkg-config.freedesktop.org/releases/pkg-config-0.27.1.tar.gz
tar -zxvf pkg-config-0.27.1.tar.gz
cd pkg-config-0.27.1
编译
./configure
make
make check
make install
验证是否已安装 （同最初命令）
pkg-config --version
0.27.1
五、安装ffmpeg
安装gcc编译器
yum install gcc
下载ffmpeg
6.0版本，快速下载
wget http://ffmpeg.org/releases/ffmpeg-6.0.tar.xz
(或)访问官网选择任意版本
http://ffmpeg.org/download.html#releases
解压
tar -zxvf ffmpeg-6.0.tar.xz
mv ffmpeg-6.0/ /usr/local/ffmpeg/
配置ffmpeg
cd /usr/local/ffmpeg
./configure --enable-gpl --enable-libx264 --enable-static --disable-shared --enable-encoder=libx264 --extra-libs=-ldl
编译执行
make && sudo make install
查询ffmpeg
[root@x ffmpeg]# ffmpeg
ffmpeg: error while loading shared libraries: libx264.so.164: cannot open shared object file: No such file or directory
如果报错没找到文件，则：
# 先找到缺失文件的位置，例如执行
find / -name ‘libx264.so.164’
# 得到
/home/soft/x264/libx264.so.164
/usr/local/lib/libx264.so.164
# 修改ld.so.conf
vim /etc/ld.so.conf
最后一行添加：/usr/local/lib/
[root@x home]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/lib/
# 加载改动
ldconfig
检测是否安装成功
[root@x home]# ffmpeg

配置环境变量
vim /etc/profile
# 新增
PATH=$PATH:/usr/local/ffmpeg/bin
export PATH
# 加载配置
source /etc/profile
六、测试
选择网络视频连接，进行下载测试，成功即全流程结束。
ffmpeg -i http://xxx.com/x.m3u8 -c:v libx264 -y -t 60 -timeout 100000 /home/test.ts
这些包我好像都上传了，不知道有没有审核过，应该设置了几个积分
