】Tutorial

This test is only used to verify if the camera is functioning properly. It runs a test program on Duo to stream video,
and then using VLC media player on a PC to receive the video stream.

1] Make sure you can SSH into the Duo device using USB networking (RNDIS).
The default firmware SSH username and password are root/milkv.

2] Download the test file package from the link provided

duo_camera_test_v0.2.tar.gz

3] Transfer it to Duo using SCP or any other method.

scp duo_camera_test_v0.2.tar.gz root@192.168.42.1:/root/

4] Execute the program
Log in to the Duo terminal

ssh root@192.168.42.1

Unpack the test package

tar zxf duo_camera_test_v0.2.tar.gz -C /

Enter the test program directory

cd /mnt/data/install/

Execute the test program to start streaming

./CviIspTool.sh 64M

In normal circumstances, the terminal will display the following log at the end

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...

5] Play video by VLC media player

The link starting with 'rtsp:', replace the IP with the IP address of Duo, and that will be the streaming address to use in VLC media player.

On your PC, open VLC media player. Go to the 'Media' menu and select 'Open Network Stream' In the 'Network' tab, enter the following URL in the 'Please enter a network URL' field.

rtsp://192.168.42.1:8554/stream0

Click 'Play' and you will be able to see the streaming video from the camera.
