<p>我这边是通过Nux Dextop仓库来安装FFmpeg。</p>
<p>（1） 安装EPEL仓库</p>
<div class="jb51code"><pre class="brush:bash;">sudo yum install -y epel-release
</pre></div>
<p>（2）下载并安装Nux Dextop仓库的RPM包</p>
<div class="jb51code"><pre class="brush:bash;">sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
</pre></div>
<p>（3）更新YUM缓存</p>
<div class="jb51code"><pre class="brush:bash;">sudo yum update -y
</pre></div>
<p>（4） 安装FFmpeg</p>
<div class="jb51code"><pre class="brush:bash;">sudo yum install -y ffmpeg ffmpeg-devel
</pre></div>
<p>（5）验证安装</p>
<div class="jb51code"><pre class="brush:bash;">ffmpeg -version</pre></div>
<p style="text-align:center"><img alt="" src="https://img.jbzj.com/file_images/article/202502/202502231038531.png" /></p>
<p class="maodian"><a name="_label1"></a></p><h2>2、安装PHP</h2>
<div class="jb51code"><pre class="brush:bash;">sudo yum install php php-cli</pre></div>
<p>验证安装</p>
<div class="jb51code"><pre class="brush:bash;">php -v</pre></div>
<p style="text-align:center"><img alt="" src="https://img.jbzj.com/file_images/article/202502/202502231038532.png" /></p>
<p class="maodian"><a name="_label2"></a></p><h2>3、php脚本</h2>
<div class="jb51code"><pre class="brush:php;"><?php
// 设置输入视频文件、切片时长（秒）和输出目录
$videoFile = '/data/video/input.mp4'; // 输入视频文件路径
$segmentDuration = 10; // 切片时长，单位：秒
$outputDir = 'output'; // 输出目录
// 确保输出目录存在
if (!is_dir($outputDir)) {
mkdir($outputDir, 0777, true);
}
// 构建并执行FFmpeg命令以生成.m3u8播放列表和.ts切片文件
// 使用'-strict -2'参数允许使用实验性编码器'aac'
$cmd = "ffmpeg -i " . escapeshellarg($videoFile) .
" -codec:v libx264 -codec:a aac -strict -2 -hls_time " . escapeshellarg($segmentDuration) .
" -hls_list_size 0 -hls_flags delete_segments " . escapeshellarg($outputDir . "/output.m3u8");
// 或者，如果您有 'libfdk_aac' 可用，可以替换 '-codec:a aac -strict -2' 为 '-codec:a libfdk_aac'
// $cmd = "ffmpeg -i " . escapeshellarg($videoFile) .
// " -codec:v libx264 -codec:a libfdk_aac -hls_time " . escapeshellarg($segmentDuration) .
// " -hls_list_size 0 -hls_flags delete_segments " . escapeshellarg($outputDir . "/output.m3u8");
shell_exec($cmd);
// 设置目标目录
$targetDir = 'target_dir';
if (!is_dir($targetDir)) {
mkdir($targetDir, 0777, true);
}
// 检查.m3u8文件是否存在
$playlistFile = $outputDir . '/output.m3u8';
if(file_exists($playlistFile)){
// 复制.m3u8播放列表文件
copy($playlistFile, $targetDir . '/output.m3u8');
// 获取所有.ts切片文件，并将其复制到目标目录
$tsFiles = glob($outputDir . '/*.ts');
foreach ($tsFiles as $tsFile) {
copy($tsFile, $targetDir . '/' . basename($tsFile));
}
echo "视频切片及文件复制操作完成。\n";
} else {
echo "FFmpeg处理失败，未找到输出文件。\n";
}

<p class="maodian"><a name="_label3"></a></p><h2>4、创建目录（/data）</h2>
<p>视频目录：/data/video</p>
<p>php脚本目录：/data 脚本名称：slice_video.php </p>
<p class="maodian"><a name="_label4"></a></p><h2>5、执行脚本</h2>
<div class="jb51code"><pre class="brush:bash;">php slice_video.php
</pre></div>
<p class="maodian"><a name="_label5"></a></p><h2>6、生成的切片文件夹</h2>
<p style="text-align:center"><img alt="" src="https://img.jbzj.com/file_images/article/202502/202502231038533.png" /></p>
<p class="maodian"><a name="_label6"></a></p><h2>7、安装Nginx</h2>
<p>（1）安装</p>
<div class="jb51code"><pre class="brush:bash;">sudo yum install nginx -y
</pre></div>
<p>（2）启动 Nginx</p>
<div class="jb51code"><pre class="brush:bash;">sudo systemctl start nginx
sudo systemctl enable nginx
</pre></div>
<p>（3） 检查 Nginx 状态</p>
<div class="jb51code"><pre class="brush:bash;">sudo systemctl status nginx
</pre></div>
<p>（4）关闭防火墙</p>
<div class="jb51code"><pre class="brush:bash;">sudo systemctl stop firewalld
sudo systemctl disable firewalld
sudo systemctl status firewalld
</pre></div>
<p>（5）nginx.conf文件配置</p>
<p>文件位置：/etc/nginx/nginx.conf</p>
<div class="jb51code"><pre class="brush:php;">sudo nginx -t# 测试配置文件语法是否正确
sudo systemctl reload nginx# 重新加载 Nginx使配置生效
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_formatmain'$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log/var/log/nginx/access.logmain;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 4096;
include /etc/nginx/mime.types;
default_type application/octet-stream;
include /etc/nginx/conf.d/*.conf;
server {
listen 80;
server_name 192.168.126.129;
location /hls/ {
alias /data/target_dir/; # 替换为你的实际目录路径
types {

video/mp2t ts;
}
add_header 'Cache-Control' 'no-cache';
add_header 'Access-Control-Allow-Origin' '*';
}
}
}
</pre></div>
<p>8、编写html播放器</p>
<div class="jb51code"><pre class="brush:xhtml;"><!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>HLS Stream Player</title>
<script src="https://cdn.jsdelivr.net/npm/hls.js@latest"></script>
</head>
<body>
<h1>视频播放器</h1>
<video id="video" controls autoplay></video>
<script>
if(Hls.isSupported()) {
var video = document.getElementById('video');
var hls = new Hls();
// 这里替换为你的.m3u8文件的实际URL
var url = 'http://192.168.126.129/hls/output.m3u8'; // 替换为你的实际URL
hls.loadSource(url);
hls.attachMedia(video);
hls.on(Hls.Events.MANIFEST_PARSED, function() {
video.play();
});
} else if (video.canPlayType('application/vnd.apple.mpegurl')) {
// 如果浏览器直接支持HLS，则可以直接设置src
video.src = 'http://192.168.126.129/hls/output.m3u8'; // 替换为你的实际URL
video.addEventListener('loadedmetadata', function() {
video.play();
});
}
</script>
</body>
</html></pre></div>
