Live Video Streaming

Warning

LVDS only: Use Video Streaming for LVDS configuration if your AstrOptix board is connected to a single LVDS camera. The camera streams on /dev/video0.

Warning

LVDS + MIPI: Use Video Streaming for LVDS + MIPI configuration if your AstrOptix board is connected to both an LVDS camera and a MIPI CSI-2 camera simultaneously. The LVDS camera streams on /dev/video0 and the MIPI camera streams on /dev/video1.

1. Video Streaming for LVDS

1.1 Verify Video Node

Step 19: Check the Video Device Node

ls /dev/video*

The output should display /dev/video0. If the node is present, the driver has loaded successfully and the camera is ready.

Note:

If the video node is not detected, refer to Troubleshooting

1.2 Boost Clocks & Enable Debug

Note:

If you have the rc.local file, continue with the step below. If not, contact the Oppila Support to obtain it before proceeding.

Step 20: Open a Terminal and Run rc.local

  • Press Ctrl + Alt + T and run:
sudo ./rc.local

1.3. Start GStreamer Pipeline

Step 21: Run the GStreamer Command

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY ! videoconvert ! xvimagesink
2. Video Streaming for LVDS + MIPI

2.1 Verify Video Node

Step 19: Check the Video Device Node

ls /dev/video*

The output should display /dev/video0. If the node is present, the driver has loaded successfully and the camera is ready.

Note:

If the video node is not detected, refer to Troubleshooting

2.2 Boost Clocks & Enable Debug

Note:

If you have the rc.local file, continue with the step below. If not, contact the Oppila Support to obtain it before proceeding.

Step 20: Open a Terminal and Run rc.local

  • Press Ctrl + Alt + T and run:
sudo ./rc.local

2.3 Start GStreamer Pipeline

Step 21: Run the GStreamer Commands

Run the following command to stream from the LVDS camera (/dev/video0):

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY ! videoconvert ! xvimagesink

Open a second terminal and run the following to stream from the MIPI camera (/dev/video1):

gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,format=UYVY ! videoconvert ! xvimagesink

If the pipeline starts successfully, a video window will appear displaying the live camera feed.

Note:

If you encounter a green screen, black screen, or no video output after launching the GStreamer pipeline, refer to Troubleshooting.
