現在不具合の再現確認を実施しています。
１：verdin iMX8MP
２：Torizon-OS
３：Docker を使用してUSBカメラを使用してHDMIからモニタに映像を表示させたい
４：CPUを高負荷の状態にし、モニタの表示が揺らぐ、乱れる現象を再現したい
カメラは動作しているようだが、モニタに画像が表示されない。
初歩的なことだと思うが教えてください。

Based on the context provided, here are some steps you can take to troubleshoot the issue where the USB camera is not displaying images on the HDMI monitor when using Verdin iMX8MP with Torizon-OS and Docker:
-
Check Connections: Ensure that the USB camera is properly connected to the Verdin iMX8MP and that the HDMI cable is securely connected to both the monitor and the board. Also, verify that the monitor is set to the correct input source.
-
Verify Settings:
- Confirm that the USB camera settings within Torizon-OS are correct. Make sure the Docker container is configured to access the USB device.
- Check that the HDMI output settings are correctly configured.
-
Monitor Resources: Observe the CPU usage to see how much resource is being consumed during high load. High CPU load can cause instability in video processing.
-
Check Drivers: Ensure that the USB camera drivers are correctly installed. Missing drivers can prevent the camera from being recognized.
-
Docker Configuration: Verify that the Docker container has the necessary permissions to access the USB camera. Use the
--deviceflag to allow access to the USB device if needed. -
Consider High Load Performance: High CPU load can lead to unstable video output. Consider optimizing resources or reducing load.
If these steps do not resolve the issue, further investigation into specific error messages or logs may be necessary to identify the root cause.
