iQS-Streampipe: How to Change the Custom Model and Video Source

This SDK guide covers editing config.json to change the model, video source and channel count for iQS-Streampipe — for running the pipeline on your own video or your own detection model.

Supported Versions

Choose the iQ-Studio version that matches your platform. To check your BSP version, run cat /etc/innodisk/BSP-version on the platform.

For v0.0.10, run git checkout v0.0.10 in the iQ-Studio directory before ./install.sh. To return to the latest version, run git checkout main.

How to Deploy

1. 1
   At least one UVC camera

   • 1080p/30fps (1920x1080 pixels)
   • MJPEG compression format

   Due to limited bandwidth, do not use more than 3 UVC cameras at once.
2. 2
   At least one MP4 video uses the H.264 codec.

How to modify the content displayed, please refer to the config.json file in the current directory.

1. 1

   To open and edit the config.json file. (default parameter)

   {{ cb2.fname }} bash

   

3. 3
   Modify config.json. We have changed the video under id: 1 to coco_detect.mp4. You may replace coco_detect.mp4 with your own video file if desired.

   This config is not the default config in the Docker container.

   Enter the Relative Path into the config file.

   

4. 4
   After you finish modifying.

   save and close the config.json.

   {{ cb3.fname }} text

5. 5
   Run the iqs-launcher

   You must add the --other "-c config.json" option to change the videos.

   {{ cb4.fname }} bash

6. 6
   Change the display of ID 1 to the specified view.

How to use a UVC camera to capture video frames for real-time prediction.

When a UVC camera's USB plug is connected to the platform's USB port, the video prediction will automatically switch to and display the real-time prediction results from the UVC camera feed.

When multiple cameras are plugged in, the results will be replaced based on channels, starting with channel 0, then channel 1, and so on.

Known Issue

The current Qualcomm codec driver may under certain conditions, cause the system to restart unexpectedly. If this occurs, re-run the process to continue.
