H264/H265 rtsp服务 2. H264 rtmp服务 3. OSD(时间)功能 4. 海思AIISP 5. 海思图像自适应 6. 海思编码自适应 7. Mp4文件保存(使用海思中间件HiXuanyuanV100R001C01SPC020中的mp4库) 8. 抓拍JPG 9. Yolov5(通过rtsp视频验证) 10. vo(BT1120 1080p@60) 当前支持的sensor为: 1. OS04A10,OS04A10_WDR,OS08A20(for 3519DV500),OS08A20_WDR(for 3519DV500) #### 流程图 ``` |-------->jpg保存 | | | |---------------->venc sub(固定720 x576)-------->rtsp stream2 | | (和vi相同分辨率) (和vi相同分辨率) mipi/vi-------->vpss grp(0)-------->vpss chn(0)---------->venc main(分辨率大小由venc.json中指定,例如1920x1080)--------->rtsp stream1 | | | | | |-------->mp4保存 | | | |---------------->vo | | vpss缩放至(640x640) |--------------->vpss chn(1)---------->yolov5-------->rtsp stream3 ``` #### 编译方法 以下为sdk 021的编译方法，如果是sdk 020,需要修改相应的路径 1. 按照Hi3519DV500_SDK_V2.0.2.1/smp/a55_linux/source/bsp/readme_cn.txt文档编译SDK 2. 按照如下命令，编译app ``` cd Hi3519DV500_SDK_V2.0.2.1/smp/a55_linux/source/mpp/sample git clone https://gitee.com/shumjj/3516dv500_app.git cd 3516dv500_app make ``` #### 运行 ``` //step1: 复制rootfs/opt/ceanic到板子/opt/目录 cp /mnt/rootfs/opt/ceanic /opt/ -Rdp //step2: 加载ko cd /opt/ceanic/ko ./load3519dv500 -i //step3: 运行app(需要确保/opt/ceanic/etc/vi.json中的sensor和板子匹配) cd /opt/ceanic/bin ./ceanic_app ``` #### 目录结构 ``` ├── aiisp //海思AI ISP实现 ├── app_std.h //app头文件 ├── device //海思设备相关 ├── doc //doc ├── json //json库 ├── log //log库 ├── main.cpp ├── Makefile ├── README.md ├── rootfs //SDK rootfs修改部分 ├── rtmp //rtmp 实现 ├── rtsp //rtsp 实现 ├── thirdlibrary //第三方库 └── util //通用头文件 ``` #### RTSP ##### RTSP URL url为: ``` //main stream rtsp://192.168.10.98/stream1 //sub stream rtsp://192.168.10.98/stream2 //yolov5 stream(需要配置文件/opt/ceanic/yolov5/yolov5.json中开启yolov5) rtsp://192.168.10.98/stream3 ``` ##### VLC连接RTSP vlc连接方法:媒体->打开网络串流->输入RTSP URL ![avatar](doc/rtsp_open.jpg) #### RTMP 1. rtmp功能默认不开启,需要修改/opt/ceanic/etc/net_service.json文件,enable修改为1 2. rtmp当前只支持h264,需要修改/opt/ceanic/etc/venc.json中编码类型为h264 ##### RTMP测试流程 1. ubuntu下启动nginx测试服务器程序 2. 修改net_service.json中enable为1 3. 修改venc.json中H264_CBR(或H264_VBR) 4. 运行设备程序ceanic_app,运行成功的话,设备会connect到nginx,并发布视频(发布的视频url在net_service.json中设置) 5. pc端运行vlc,输入url,从nginx拉流，观看视频 ##### RTMP测试服务器(nginx)搭建(ubuntu20.04) 1. 按照如下命令编译nginx,需要注意的是运行nginx, -C 后面的参赛需要是全路径 ``` wget http://nginx.org/download/nginx-1.21.6.tar.gz wget https://github.com/arut/nginx-rtmp-module/archive/master.zip tar -xf nginx-1.21.6.tar.gz unzip master.zip cd nginx-1.21.6/ ./configure --prefix=`pwd`/mybuild --with-http_ssl_module --add-module=../nginx-rtmp-module-master make && make install cd mybuild/sbin sudo ./nginx -c /home/mjj/work/nginx-1.21.6/mybuild/sbin/nginx_rtmp.conf ``` 2. nginx_rtmp.conf见rtmp目录 3. 查看nginx rtmp服务是否开启 ``` ~/work/nginx-1.21.6/mybuild/sbin$ sudo netstat -na | grep 1935 tcp 0 0 0.0.0.0:1935 0.0.0.0:* LISTEN ``` 4. 查看rtmp 日志 错误日志如下 ``` mjj@mjj-VirtualBox:~/work/nginx-1.21.6/mybuild/sbin$ tail ../logs/error.log 024/01/09 15:59:54 [info] 16432#0: *100 disconnect, client: 192.168.10.200, server: 0.0.0.0:1935 2024/01/09 15:59:54 [info] 16432#0: *100 deleteStream, client: 192.168.10.200, server: 0.0.0.0:1935 2024/01/09 16:03:57 [info] 16432#0: *98 disconnect, client: 192.168.10.98, server: 0.0.0.0:1935 2024/01/09 16:03:57 [info] 16432#0: *98 deleteStream, client: 192.168.10.98, server: 0.0.0.0:1935 2024/01/09 16:03:57 [info] 16432#0: *97 disconnect, client: 192.168.10.98, server: 0.0.0.0:1935 2024/01/09 16:03:57 [info] 16432#0: *97 deleteStream, client: 192.168.10.98, server: 0.0.0.0:1935 ``` 连接日志如下 ``` tail ../logs/access.log 192.168.10.200 [09/Jan/2024:15:34:32 +0800] PLAY "live" "stream2" "" - 478 31874328 "" "LNX 9,0,124,2" (4m 8s) 192.168.10.98 [09/Jan/2024:15:49:24 +0800] PUBLISH "live" "stream2" "" - 151203194 409 "" "" (19m 27s) 192.168.10.98 [09/Jan/2024:15:49:24 +0800] PUBLISH "live" "stream1" "" - 603082173 409 "" "" (19m 27s) 192.168.10.200 [09/Jan/2024:15:53:48 +0800] PLAY "live" "stream1" "" - 1549 453211948 "" "LNX 9,0,124,2" (19m 8s) 192.168.10.98 [09/Jan/2024:15:58:50 +0800] PUBLISH "live" "stream2" "" - 4021860 409 "" "" (32s) 192.168.10.98 [09/Jan/2024:15:58:50 +0800] PUBLISH "live" "stream1" "" - 16027268 409 "" "" (32s) 192.168.10.200 [09/Jan/2024:15:59:41 +0800] PLAY "live" "stream1" "" - 411 11245160 "" "LNX 9,0,124,2" (26s) 192.168.10.200 [09/Jan/2024:15:59:54 +0800] PLAY "live" "stream2" "" - 378 1600363 "" "LNX 9,0,124,2" (13s) 192.168.10.98 [09/Jan/2024:16:03:57 +0800] PUBLISH "live" "stream2" "" - 37391403 409 "" "" (4m 50s) 192.168.10.98 [09/Jan/2024:16:03:57 +0800] PUBLISH "live" "stream1" "" - 149073600 409 "" "" (4m 50s) ``` 5. nginx 开启/关闭 ``` //开启命令 ~/work/nginx-1.21.6/mybuild/sbin$sudo ./nginx -c /home/mjj/work/nginx-1.21.6/mybuild/sbin/nginx_rtmp.conf //关闭命令 ~/work/nginx-1.21.6/mybuild/sbin$sudo ./nginx -s stop ``` ##### VLC连接nginx 1. 先根据[RTMP测试服务器搭建](#####RTMP测试服务器(nginx)搭建(ubuntu20.04))章节搭建好nginx 服务器 2. 根据[RTMP配置文件说明](#####RTMP配置文件说明)中说明获取到RTMP URL 3. 打开vlc->媒体->打开网络串流->输入RTMP URL ![avatar](doc/rtmp_open.jpg) #### 配置文件说明 [配置文件说明](doc/set.md) #### 调试记录 [调试记录](doc/debug_log.md) #### 合作交流 联系方式: 深圳思尼克技术有限公司 jiajun.ma@ceanic.com 马佳君
