LiveNVR Onvif/RTSP流媒体软件接入监控摄像头后如何获取直播流地址进行大屏展示、播放端拉流、网页播放监控视频等

1、LiveNVR介绍

LiveNVR的安防监控的视频直播，可以按标准的Onvif/RTSP协议接入监控设备，也可以通过海康、大华、天地伟业等厂家私有SDK接入监控，实现web页面的播放和录像回放。 可以分发HTTP-FLV、WS-FLV、WebRTC、RTMP、HLS(M3U8)、RTSP等多中视频流

2、三种方法获取LiveNVR直播流地址获取

        }
    }
}

2.2、方法二浏览器F12查看播放地址

2.3、方法三安固定格式拼接

不调用开始直播可以获取播放地址吗？可以的，LiveNVR支持流地址播放直接启动通道拉流，配置规则如下：

2.3.1、HTTP端口直播流地址格式

• WEBRTC: webrtc://{ip}:{port}/rtc/stream_

• FLV: http://{ip}:{port}/flv/hls/stream_{通道号}.flv

• WS_FLV: ws://{ip}:{port}/ws-flv/hls/stream_{通道号}.flv

• HLS: http://{ip}:{port}/hls/stream_{通道号}/stream_{通道号}_live.m3u8

• RTMP: rtmp://{ip}:{port}/hls/stream_

• RTSP: rtsp://{ip}:{port}/stream_

2.3.2、HTTPS端口直播流地址格式

• WEBRTC: webrtc://{ip}:{port}/rtc/stream_

• FLV: http://{ip}:{port}/flv/hls/stream_{通道号}.flv

• WS_FLV: ws://{ip}:{port}/ws-flv/hls/stream_{通道号}.flv

• HLS: http://{ip}:{port}/hls/stream_{通道号}/stream_{通道号}_live.m3u8

• RTMP: rtmp://{ip}:{port}/hls/stream_

• RTSP: rtsp://{ip}:{port}/stream_

2.3.3、关闭静态流地址播放

livenvr.ini ->[base_config]->allow_stream_start_by_url=0 ， 默认是开启此功能的，配置后重启LiveNVR服务

[base_config]
allow_stream_start_by_url=0
