H264/H265 rtsp服务 2. H264 rtmp服务 3. OSD(时间)功能 4. HNR 5. 图像自适应 6. yolov5 rtsp视频 当前支持的sensor为: 1. OS08A20 #### 编译方法 1. 按照/SS928V100_SDK_V2.0.2.2/osdrv/readme_cn.txt文档编译SDK 2. 按照如下命令，编译app ``` cd SS928V100_SDK_V2.0.2.2/smp/a55_linux/mpp/sample git clone https://gitee.com/shumjj/ss928_app.git cd ss928_app make ``` #### 运行 1. 烧写默认rootfs,挂载nfs,假设nfs已经挂载,nfs目录为/mnt ``` // opt见版本库rootfs下 cp /mnt/opt / -Rdp cd /opt/ceanic/ko ./load_ss928v100 -i ``` 2. 复制编译的程序到板子，并手动运行 ``` ./ss928_app ``` #### 配置文件说明 ##### vi.json ``` { "sensor1" : { "flip" : 0, "fr" : 30, "h" : 2184, "name" : "OS08A20", "w" : 3840 } } ``` | 类型 | 说明 | | ---- | ---- | | flip | 保留 | | fr | 帧率 | | h | sensor视频高 | | name | sensor类型,当前支持"OS08A20","OS08A20_WDR",WDR需要和scene中的mode相匹配 | | w | sensor视频宽 | ##### venc.json ``` { "venc1" : { "bitrate" : 8000, "fr" : 30, "h" : 2184, "name" : "H264", "w" : 3840 } } ``` | 类型 | 说明 | | ---- | ---- | | bitrate | 编码码率(kbps),当前支持CBR | | fr | 编码帧率 | | h | 编码视频高 | | name | 编码类型,当前支持"H264","H265" | | w | 编码视频宽 | ##### net_service.json ``` { "net_service" : { "rtmp" : { "enable" : 1, "main_url" : "rtmp://192.168.10.97/live/stream1", "sub_url" : "rtmp://192.168.10.97/live/stream2" }, "rtsp" : { "port" : 554 } } } ``` | 类型 | 说明 | | ---- | ---- | | rtsp:port | RTSP 侦听端口,默认554 | | rtmp:enable | 0:不启用rtmp 1:启用rtmp | | rtmp:main_url | rtmp 主编码数据url | | rtmp:sub_url | rtmp 子编码数据url | ##### aiisp.json ``` { "aiisp" : { "enable" : 1, "model_file" : "/opt/ceanic/aiisp/model/normal_hnr.bin" } } ``` | 类型 | 说明 | | ---- | ---- | | enable | 1:启用 0:启用 | | model_file | 模型文件绝对路径，需要和mode中的类型匹配 | ##### scene.json ``` { "scene" : { "dir_path" : "/opt/ceanic/scene/param/sensor_os08a20", "enable" : 1, "mode" : 0 } } ``` | 类型 | 说明 | | ---- | ---- | | enable | 1:启用 0:启用 | | dir_path | scene使用的配置目录路径 | | mode | scene mode序号(见config_scenemode.ini) | #### RTSP ##### RTSP URL url为: rtsp://192.168.10.98/stream1 rtsp://192.168.10.98/stream2 rtsp://192.168.10.98/stream3 其中192.168.10.98需要修改为实际的板端地址,stream1为主编码(高清)码流，stream2为子编码(标清)码流,stream3为yolov5 视频(需要开启yolov5,/opt/ceanic/yolov5/yolov5.json) ##### 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 rtmp默认不开启,需要修改/opt/ceanic/etc/net_service.json文件 ##### 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" "" -

Device Drivers--->Real Time Clock--->Micro Crystal RV8803, Epson RX8900,按M选择模块 3. make ARCH=arm64 CROSS_COMPILE=aarch64-mix210-linux- modules 4. 生成drivers/rtc/rtc-rv8803.ko 5. 在板子上insmod后，使用date和hwclock命令修改时间 ##### uboot默认环境参赛修改 1. bootargs修改方法: 修改.config文件(该文件来源于configs目录，例如emmc版本为configs/ss928v100_emmc_defconfig) ``` CONFIG_BOOTARGS="mem=512M console=ttyAMA0,115200 clk_ignore_unused ubi.mtd=2 root=ubi0:ubifs rootfstype=ubifs rw mtdparts=nand:1M(boot),11M(kernel),32M(rootfs.ubifs)" ``` 2. bootcmd修改方法: 修改include/configs/ss928v100.h ``` #define CONFIG_BOOTCOMMAND "nand read 0x50000000 0x100000 0xb00000;bootm 0x50000000" ``` ##### initrd制作步骤 1. 参考osdrv/readme_cn.txt编译整个sdk,生成osdrv/put/rootfs_glibc_arm64文件系统 2. 参考SS928V100╱SS927V100 开发环境用户指南.pdf 6.3.4章节中的内核配置 3. 在linux目录下调用make ARCH=arm64 CROSS_COMPILE=aarch64-mix210-linux- menuconfig，在配置界面中General setup--->Initial RAM filesystem and RAM disk (initramfs/initrd) support这项按y选中后,Initramfs source file这栏中输入rootfs的路径(例如:/home/mjj/work/3403/SS928V100_SDK_V2.0.2.2/osdrv/pub/rootfs_glibc_arm64),rootfs必须是第一步中已经生成好的 4. 按照osdrv/readme_cn.txt单独编译kernel生成fip.bin,因为已经包含了rootfs，生成的fip.bin大小为13.8M左右(不含rootfs的大小在10.8M左右) 5. 烧录的时候只需要烧录uboot和fip.bin,uboot设置1M大小,fip.bin设置15M 6. uboot参赛设如下(spi nand下): ``` setenv bootcmd 'nand read 0x50000000 0x100000 0xf00000;bootm 0x50000000';sa setenv bootargs 'mem=512M console=ttyAMA0,115200 root=/dev/ram0 rw init=/init blkdevparts=mmcblk0:1M(boot),15M(kernel)';sa ```
