切分mp4视频:

ffmpeg -y \
-i "/tmp/mda-mh4d5tn0e89vvqrm.mp4" \
-hls_time "10" \
-hls_key_info_file "/tmp/enc.keyinfo" \
-hls_playlist_type "vod" \
-hls_list_size "0" \
-hls_segment_filename "/tmp/ffmpeg_%d.ts" \
"/tmp/ffmpeg_playlist.m3u8"

hls_time：指定生成 ts 视频切片的每片时间长度
hls_key_info_file：enc.keyinfo文件的位置
hls_list_size: 索引播放列表的最大列数 默认5，0 为不限制
hls_segment_filename：生成ts和m3u8文件的路径及文件名

Ubuntu 20.04安装ffmpeg详细教程-便宜VPS测评root@ubuntu-s-1vcpu-1gb-lon1-01:~# do-release-upgrade Checking for a new Ubuntu release You have not rebooted after updating a package which requires a reboot..html

测试使用：

.js/<script src=".js/0.14.9/hls.js"></script>

python -m http.server 80

如下是 index.html 

<head><meta charset='UTF-8'><title>test</title>
</head>
<body><video width=800 controls src=''>URL99</video><script src=".js/0.14.9/hls.js"></script><script>if(Hls.isSupported()) {var video3 = document.getElementsByTagName('video')[0];var hls2 = new Hls( {debug: true} );hls2.loadSource("http://192.168.50.1:60443/z/ffmpeg_0/ffmpeg_playlist.m3u8?c="+Math.random()  );hls2.attachMedia(video3);hls2.on(Hls.Events.MANIFEST_PARSED,function() { video3.play()  }); }</script>
</body>

使用ckplayer来测试（使用hls插件）：

cd /tmp;git clone ;#  .html#m102

<!DOCTYPE html>
<html><head><script type="text/javascript" src="ckplayer/hls.js/hls.min.js"></script><link rel="stylesheet" type="text/css" href="ckplayer/css/ckplayer.css"><script type="text/javascript" src="ckplayer/js/ckplayer.js"></script></head><body><div class="video" style="width: 100%; height: 500px;max-width: 800px;" ></div><script>var videoObject = {container: '.video',  //容器的ID或classNameplug:'hls.js',   //设置使用hls插件video:"http://192.168.50.1:60443/z/ffmpeg_0/ffmpeg_playlist.m3u8?c="+Math.random() };new ckplayer(videoObject);</script></body>
