Streaming Issues with Nvidia Jetson Orin Nano Dev Board Using GStreamer

Issue Overview

Users are experiencing difficulties when attempting to stream video from the Nvidia Jetson Orin Nano Dev board using GStreamer commands. The specific symptoms include:

• Resolution Problems: Users report that when streaming at a sensor resolution of 1456×1088, the output appears elongated when connected to a 1080p monitor.
• Command Errors: Commands such as gst-launch-1.0 nvarguscamerasrc ! nvvidconv ! autovideosink do not yield the desired results, and users have encountered warnings regarding deprecated plugins like nvoverlaysink.
• Frequency: These issues seem to occur consistently during setup and initial streaming attempts.
• Impact: The inability to achieve the desired video output affects user experience significantly, particularly for applications requiring specific resolutions.

Possible Causes

Several potential causes have been identified for these streaming issues:

• Hardware Limitations: The Jetson Orin Nano may have constraints in handling certain resolutions or output formats, especially when interfacing with monitors of differing specifications.
• Software Bugs: Users have noted that certain GStreamer plugins, such as nvoverlaysink, are deprecated in JetPack 5 and 6, leading to compatibility issues.
• Configuration Errors: Incorrect settings in the GStreamer pipeline could lead to unexpected behavior in video output.
• Driver Issues: Outdated or incompatible drivers may prevent proper functioning of the GStreamer commands.
• User Misconfigurations: Users may not be aware of the correct parameters needed for their specific use case, leading to poor results.

Troubleshooting Steps, Solutions & Fixes

To address the streaming issues with the Nvidia Jetson Orin Nano Dev board, follow these troubleshooting steps:

1. Verify GStreamer Installation:
   Ensure that you have the latest version of GStreamer installed on your system. Use the following command to check:

   gst-inspect-1.0 --version
   

2. Use Correct GStreamer Command:
   Instead of using deprecated plugins, try the following command:

   gst-launch-1.0 nvarguscamerasrc ! nvvidconv ! 'video/x-raw(memory:NVMM)' ! nv3dsink sync=0
   

   This command utilizes nv3dsink, which is recommended over nvoverlaysink.

3. Configure Output Properties:
   Adjust properties for nv3dsink to specify window dimensions:

   • Set window height and width according to your desired output resolution.
   • Example configuration (replace <height> and <width> with actual values):

     gst-launch-1.0 nvarguscamerasrc ! nvvidconv ! 'video/x-raw(memory:NVMM)' ! nv3dsink window-height=<height> window-width=<width>
     

4. Test Different Sinks:
   If issues persist, try different sinks available in GStreamer:

   • autovideosink
   • xvimagesink
   • nvvideosink

   Example command using xvimagesink:

   gst-launch-1.0 nvarguscamerasrc ! nvvidconv ! autovideosink
   

5. Check Monitor Settings:
   Ensure that your monitor settings are compatible with the output resolution specified in your commands.

6. Update JetPack and Drivers:
   Make sure that you are running an updated version of JetPack (5.1.1 or later) and that all drivers are correctly installed.

7. Consult Documentation:
   Review the official GStreamer documentation for any additional flags or options that may help optimize performance.

8. Community Support:
   If issues remain unresolved, consider reaching out on forums or community support channels specific to Nvidia Jetson products for further assistance.

By following these steps, users can potentially resolve their streaming issues on the Nvidia Jetson Orin Nano Dev board effectively.
