Milk-V Duo 摄像头VLC拉流 (2023-08-17 更新)

Carbon · July 8, 2023, 4:44am

该测试仅用来测试摄像头是否能正常工作，在Duo上运行测试程序推流，在PC端用VLC播放器拉流。

首先确保可以通过USB网络(RNDIS)正常ssh到Duo设备。
默认固件ssh的用户名和密码分别是root/milkv
文末链接下载测试文件包 duo_camera_test_v0.1.tar.gz 并通过scp或其他方式传到Duo上

scp duo_camera_test_v0.1.tar.gz root@192.168.42.1:/root/

登陆到Duo终端
ssh root@192.168.42.1

解压测试包
tar zxf duo_camera_test_v0.1.tar.gz -C /

进入测试程序目录
cd /mnt/data/install/

执行测试程序推流
./CviIspTool.sh 64M

正常情况下，终端最后会看到如下日志

VPSS init with src (1920, 1080) dst (1920, 1080).
CVI_VPSS_CreateGrp:0, s32Ret=0
rtsp://127.0.1.1:8554/stream0
prio:0
CVI_RTSP_SERVICE_CreateFromJsonFile[./cfg_64M.json]
[REMOTE] cvi_raw_dump_run,158: raw dump ready...
waiting for connect...

注意rtsp:开头的链接，把IP改成Duo的IP就是我们要在VLC中拉流的地址了

在PC上打开VLC播放器，菜单“媒体”中选择“打开网络串流”，选择“网络”标签，在“请输入网络URL”中输入

rtsp://192.168.42.1:8554/stream0

再点”播放“，就可以看到摄像头推流的画面了

duo_camera_test_v0.1.tar.gz
测试包链接：百度网盘请输入提取码
提取码：slut

2023-08-17 更新，支持GC2083

duo_camera_test_v0.2.tar.gz 使用方法同上，注意上传和解压时的包名
测试包链接：https://github.com/milkv-duo/Accessories/blob/master/CAM-GC2083/Software_testing/duo_camera_test_v0.2.tar.gz

注意摄像头排线的连接方向如下:

感谢，已成功

kkoolerter · July 16, 2023, 11:06am

请问下，使用什么类型的摄像头，有链接吗？谢谢！！

steven · August 15, 2023, 6:36am

请问用的什么类型摄像头，能发下摄像头的链接吗

xiaomin · August 15, 2023, 6:46am

请问摄像头什么时候发货啊，买了几天了，没什么动静

是不是排线插反了，测一下摄像头的地和板子的地是不是通的

zhaoqiankun · September 1, 2023, 7:50am

duo_camera_test_v0.2.tar.gz这个测试文件的源码有吗，希望可以借鉴一下

mortal · September 9, 2023, 6:25am

试试看配合0817版本的固件+v0.2版本的脚本试试，前提是你的摄像头是GC2083版的

wukongxuetang · September 10, 2023, 3:08am

官方采购的摄像头，我重新烧录固件，试下，看是不是还有报错

wukongxuetang · September 11, 2023, 3:44am

摄像头画面出来了，不过延迟太严重了，将近2秒的样子，估计是1080p画面尺寸太大

I need some help. I get this error when I try to connect to VLC player. Does anyone know how to fix this error

xiaomin · September 24, 2023, 6:01am

@Pukkuu6462
GC2083 requires the use of duo_ Camera_ Test_ V0.2.tar.gz

Pukkuu6462 · September 24, 2023, 8:40am

@xiaomin
Yes, this error occur when I use duo_camera_test_v0.2, but I haven’t try the v0.1 yet.

y1sssdd · October 17, 2023, 1:56pm

能不能看一下duo_camera_test_v0.2.tar.gz文件的源码想看看这个摄像头是怎么调用的

C1P81 · October 30, 2023, 8:04pm

i have the same problem

Pukkuu6462 · October 31, 2023, 5:59am

I redo every process again and it work.

Bruce · November 6, 2023, 3:35pm

Please provide source code to develop on the Duo?
Otherwise the camera is worthless!

lpmorin · November 7, 2023, 1:45am

I have the GC2083 camera and followed instruction. When opening with VLC, it immediately disconnects. I think the stream0 doesn’t send anything.
