如何在IE浏览器播放RTSP或RTMP流

好多开发者一直苦恼于如何在IE浏览器环境下,构建低延迟的RTSP或RTMP播放,对于RTSP流来说,好多公司通常的做法是把RTSP转RTMP,然后分发到RTMP服务器,然后服务器转http-flv出来,浏览器直接播放http-flv流,亦或通过flash控件直接播放RTMP流,还有就是,转hls流出来,缺点是hls流延迟更大。

以上方案未尝不可,如果对播放体验和延迟要求更高,最简单的做法是直接在IE浏览器下加载activex控件。

大牛直播SDK(Github: https://github.com/daniulive/SmarterStreaming)在现有SDK的基础上,扩展了ocx控件,用于IE浏览器下的低延迟RTMP或RTSP播放,不谦虚的说,也可能是行业内功能支持和延迟最好的RTMP和RTSP播放器(支持RTMP/RTSP H.265(hevc)播放)。

运行网页播放端之前,请确保以管理员权限注册ocx控件:regplayerocx.bat右键-->“以管理员身份运行(A)”,同理,反注册也是需要管理员身份。

注意:大牛直播RTSP/RTMP播放OCX控件只适用于微软IE浏览器。
