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,在足够稳定的前提下,也可能是行业内功能支持最全和延迟最低的RTMP和RTSP播放器。
废话不多说,先上图:
1. 功能齐全的单画面RTMP流或RTSP流播放:
2. 同时播放4路RTMP流或RTSP流画面:
对应封装接口:
ULONG NT_SetLogPath();
ULONG NT_Open();
ULONG NT_Close();
ULONG NT_StartPlay();
ULONG NT_StopPlay();
ULONG NT_SetMute(LONG is_mute);
ULONG NT_SetURL(LPCTSTR url);
ULONG NT_SetBuffer(LONG buffer);
ULONG NT_SetRTSPTcpMode(LONG isUsingTCP);
ULONG NT_SetRtspTimeout(LONG timeout);
ULONG NT_SetRtspAutoSwitchTcpUdp(LONG is_auto_switch_tcp_udp);
ULONG NT_SetFastStartup(LONG isFastStartup);
ULONG NT_SetLowLatencyMode(LONG mode);
ULONG NT_SetFlipVertical(LONG is_flip);

ULONG NT_FullScreen();
void OnSDKEventReceived(ULONG event_id, ULONG param1);
void OnVideoSizeReceived(ULONG width, ULONG height);
设置LOG存放路径:

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:\\");
