Live Video Streaming

Verify Video Node

Step 10: 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.

Boost Clocks & Enable Debug

Step 11: Open a Terminal and Run rc.local

• Press Ctrl + Alt + T and run:

cd ~/OPPILA_ORIN_L4T_36.5.0_INTEGRATION_PM/

sudo ./rc.local

Format Selection

Step 12: Select the Input Format

The PAL–MIPI bridge board can decode both PAL and NTSC input signals. Before streaming, set the input video standard so the board interprets the incoming camera signal correctly.

Run the following command, replacing <input> with the value that matches your camera's standard:

v4l2-ctl -d /dev/v4l-subdev2 --setctrl=standard_select=<input>

For example, to set the input standard to PAL:

v4l2-ctl -d /dev/v4l-subdev2 --setctrl=standard_select=5

Note:

If you are unsure of your camera's standard, use 0 to let the board autodetect it.

Dynamic Camera Selection

The PAL–MIPI bridge board supports three composite camera inputs — 0, 1, and 2. By default, the board streams from input 0. If your camera is connected to a different input, switch to it using the dynamic_camera_switch.sh script bundled with the driver package.

Step 13: Select the Camera Input

cd ~/OPPILA_ORIN_L4T_36.5.0_INTEGRATION_PM/

sudo chmod +x dynamic_camera_switch.sh

Run the script with the input number (0, 1, or 2) of the connected camera:

sudo ./dynamic_camera_switch.sh <input>

For example, if your camera is connected to input 1, run:

sudo ./dynamic_camera_switch.sh 1

The video feed switches to the selected composite input immediately.

Video Streaming Script

Step 14: Select and Run the Stream

Run the script that matches your camera's video standard.

• For a PAL camera:

./video_stream_pal.sh

• For an NTSC camera:

./video_stream_ntsc.sh

Once the script runs successfully, a window opens showing the live camera feed.
