最近主播跟游戏主播很火啊,相对其他web应用,视频直播相对来说还是有点复杂。使用FMS搭建了服务端测试一下,直播还是不够稳定。后来试了下阿里云视频服务,感觉还可以,但是它没有提供客户端。然后找到了网易云视频,它有提供了客户端,试用一下,网易云延迟比阿里云会低点,然后就选他作为视频直播服务。网易云的api示例是java的,问客服有没有php的,然后发给我一个网易云信的api。没办法自己写个,接口也简单。

网易有提供window客户端,在使用的时候出现卡顿现象,所以还是直接使用OBS。OBS是款免费的视频直播客户端,配置也简单。在串流里填下url即可开始直播。
这样就可以开始直播。
播放器的话使用video.js即可。【推荐阅读:Node.js视频教程】
<video id="zbvideo" class="video-js vjs-default-skin" controls preload="none" width="90%" height="398" poster="/static/images/videobg.jpg" data-setup="{}"> <source src="{$data.zb_http}" /> <source src="{$data.zb_hls}" type="application/x-mpegURL" /> <source src="{$data.zb_rtmp}" type="rtmp" /> </video> <link href="/plugin/videojs/video-js.css" rel="stylesheet"> <script src="/plugin/videojs/ie8/videojs-ie8.min.js"></script> <script src="/plugin/videojs/video.js"></script>
这样就完成一个直播服务了.
添加公开课根据api自动生成直播地址,刷新直播地址,到期自动删除直播地址。
