PHP调用FFmpeg实现视频切片

注使用的视频为mp4转换成.m3u8播放列表和.ts切片文件1、安装FFmpeg我这边是通过Nux Dextop仓库来安装FFmpeg。1 安装EPEL仓库1sudoyuminstall-y epel-release2下载并安装Nux Dextop仓库的RPM包1sudorpm --importhttp://li.nux.ro/download/nux/RPM-GPG-KEY-nux.rosudorpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm3更新YUM缓存1sudoyum update -y4 安装FFmpeg1sudoyuminstall-y ffmpeg ffmpeg-devel5验证安装1ffmpeg -version2、安装PHP1sudoyuminstallphp php-cli验证安装1php -v3、php脚本123456789101112131415161718192021222324252627282930313233343536373839?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$outputDiroutput;// 输出目录// 确保输出目录存在if(!is_dir($outputDir)) {mkdir($outputDir, 0777, true);}// 构建并执行FFmpeg命令以生成.m3u8播放列表和.ts切片文件// 使用-strict -2参数允许使用实验性编码器aac$cmdffmpeg -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($cmd);// 设置目标目录$targetDirtarget_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,$targetDir./output.m3u8);// 获取所有.ts切片文件并将其复制到目标目录$tsFilesglob($outputDir./*.ts);foreach($tsFilesas$tsFile) {copy($tsFile,$targetDir./.basename($tsFile));}echo视频切片及文件复制操作完成。\n;}else{echoFFmpeg处理失败未找到输出文件。\n;}?4、创建目录/data视频目录/data/videophp脚本目录/data 脚本名称slice_video.php5、执行脚本1php slice_video.php6、生成的切片文件夹7、安装Nginx1安装1sudoyuminstallnginx -y2启动 Nginx12sudosystemctl start nginxsudosystemctlenablenginx3 检查 Nginx 状态1sudosystemctl status nginx4关闭防火墙123sudosystemctl stop firewalldsudosystemctl disable firewalldsudosystemctl status firewalld5nginx.conf文件配置文件位置/etc/nginx/nginx.conf1234567891011121314151617181920212223242526272829303132333435363738394041424344454647sudo 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_format main$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.log main;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 {application/vnd.apple.mpegurl m3u8;video/mp2t ts;}add_headerCache-Controlno-cache;add_headerAccess-Control-Allow-Origin*;}}}8、编写html播放器1234567891011121314151617181920212223242526272829303132333435!DOCTYPE htmlhtmllangenheadmetacharsetUTF-8titleHLS Stream Player/titlescriptsrchttps://cdn.jsdelivr.net/npm/hls.jslatest/script/headbodyh1视频播放器/h1videoidvideocontrols autoplay/videoscriptif(Hls.isSupported()) {var video document.getElementById(video);var hls new Hls();// 这里替换为你的.m3u8文件的实际URLvar url http://192.168.126.129/hls/output.m3u8; // 替换为你的实际URLhls.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srcvideo.src http://192.168.126.129/hls/output.m3u8; // 替换为你的实际URLvideo.addEventListener(loadedmetadata, function() {video.play();});}/script/body/html到此这篇关于PHP调用FFmpeg实现视频切片的文章就介绍到这了,
