Hello! It looks like you’re encountering some issues with your GStreamer pipeline on the Verdin iMX8M Plus module. Let’s go through some steps to help you troubleshoot and resolve these errors:

  1. Verify Plugins: Ensure all necessary GStreamer plugins are installed. Use gst-inspect-1.0 to check for videotestsrc, videoconvert, and autovideosink. Missing plugins can lead to critical errors.

  2. Utilize Hardware Acceleration: The Verdin iMX8M Plus supports hardware acceleration, which is beneficial for video tasks. Check for plugins that leverage this, such as those with ‘imx’ or ‘vpu’ in their names, using gst-inspect-1.0.

  3. Check Pipeline Configuration: Double-check your pipeline setup to ensure elements are correctly linked and compatible. Use gst-inspect-1.0 to verify the capabilities of each element.

  4. Increase Debugging Level: Set GST_DEBUG=3 to get more detailed error messages, which can help identify the issue.

  5. File Descriptor Limits: The file descriptor error might indicate a system resource issue. Check your limits with ulimit -n and increase them if needed.

  6. Try Different Video Sinks: If autovideosink is problematic, try alternatives like xvimagesink or waylandsink to see if the issue persists.

By following these steps, you should be able to identify and resolve the issues with your GStreamer pipeline. If the problem continues, consider testing with a simpler pipeline to further isolate the issue.
