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。

最新的系统镜像 V1.0.7 已经集成了推流测试程序，不需要再下载测试包传到 Duo 中了。

The latest system image V1.0.7 has integrated the test program, and there is no need to download the test package and transfer it to Duo.

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.
