如何在IE浏览器播放RTSP或RTMP流

2022-04-08 11:41:46

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，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。

设置LOG存放路径：

ULONG CSmartPlayerActiveXCtrl::NT_SetLogPath(LPCTSTR log_path)

请于NT_Open() 之前调用，代码示例：

var obj = document.getElementById("SmartPlayerActiveX");
				
//如需记录log文件，请确保log路径存在, 如多级目录, 可按照"D:\\Daniulive\\log"类似格式设定, 记录文件名: smart_sdk.log

obj.NT_SetLogPath("D:\\");
