分片上传的核心思路：
1.将文件按一定的分割规则（静态或动态设定，如手动设置20M为一个分片），用slice分割成多个数据块。
2.为每个文件生成一个唯一标识Key，用于多数据块上传时区分所属文件。
3.所有分片上传完成，服务端校验合并标识为Key的所有分片为一个最终文件。
分片上传到意义：
将文件分片上传，在网络环境不佳时，可以对文件上传失败的部分重新上传，避免了每次上传都需要从文件起始位置上传的问题。
分片的附带好处还能很方便的实现进度条。
分片上传的原理：
使用ffmpeg，把视频文件切片成m3u8，并且通过springboot，可以实现在线的点播。
客户端上传视频到服务器，服务器对视频进行切片后，返回m3u8，封面等访问路径。可以在线的播放。
准备工作：
需要先在linux下安装FFmpeg，并配置环境变量
一：下载、解压
使用命令下载：
wget https://johnvansickle.com/ffmpeg/release-source/ffmpeg-4.1.tar.xz
#使用命令解压：
cd /root/FFmpeg
tar -xvJf ffmpeg-4.1.tar.xz
# 编辑准备
cd /root/FFmpeg/ffmpeg-4.1 # 切换到ffmpeg-4.1目录
yum install gcc # 安装gcc编译器yasm安装包
cd /root/FFmpeg
wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz #下载源码包
tar zxvf yasm-1.3.0.tar.gz #解压
cd yasm-1.3.0 #进入目录
./configure #配置
make && make install #编译安装安装FFmpeg
cd /root/FFmpeg/ffmpeg-4.1/
./configure --enable-shared --prefix=/usr/local/ffmpeg-4.1
make && make install #编译安装下载x264
cd /root/libx264/
yum -y install git
git clone https://git.videolan.org/git/x264.git安装nasm
tar -xvf nasm-2.14.02.tar.gz
cd nasm-2.14.02
./configure
make
sudo make install
#查看是否安装成功
nasm -version安装x264
cd /root/FFmpeg/libx264/x264
./configure --prefix=/usr/softinstall/x264/ --includedir=/usr/local/include --libdir=/usr/local/lib --enable-shared
make
sudo make install安装FFmpeg
#配置 /etc/ld.so.conf
vim /etc/ld.so.conf #通过vim指令进入位于etc目录中的ld.so.conf
#输入i进入插入模式，将第二行的内容插入到该文件
include ld.so.conf.d/*.conf
/usr/local/ffmpeg-4.1/lib
ldconfig #ldconfig 是一个动态链接库管理命令，其目的为了让动态链接库为系统所共享。
make
sudo make install
# ffmpeg -i /root/FFmpeg/wukel.mp4 -c:v libx264 -c:a copy -hls_key_info_file /root/FFmpeg/video_folder/20220308/test1/ -hls_time 15 -hls_playlist_type vod -hls_segment_filename %06d.ts index.m3u8
ldd ffmpeg
cd /root/FFmpeg/ffmpeg-4.1
./configure --prefix=/usr/softinstall/ffmpeg --enable-gpl --enable-shared --enable-libx264
# 配置环境变量
vim /etc/profile
#配置如下
export FFMPEG_HOME=/usr/local/ffmpeg-4.1
export PATH=$FFMPEG_HOME/bin:$PATH
#修改完使用命令退出
~:wq
source /etc/profile
# 测试
ffmpeg -version
