Software testing

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.

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

The latest firmware has integrated test program, please use V1.0.8 or Latest Firmware.

Duo256M and DuoS added face detection demo while pushing the stream.

Log in to the Duo terminal:

ssh root@192.168.42.1

Execute the test program to start streaming:

camera-test.sh

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...

Note 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.

Duo:

rtsp://192.168.42.1:8554/stream0

Duo256M and DuoS:

rtsp://192.168.42.1/h264

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