Hello,

I’m sorry to hear about the issues you’re experiencing with RTSP video streaming in QGroundControl. Given that your independent GStreamer test runs smoothly, it seems the problem may lie within QGroundControl’s handling of the GStreamer pipeline.

Here are some steps you can take to address this issue:

  1. Adjust GStreamer Pipeline in QGroundControl:

    • QGroundControl uses GStreamer for video streaming, and it might be possible to adjust the pipeline configuration. Check QGroundControl’s settings or configuration files to see if you can modify the GStreamer pipeline parameters. Optimizing the pipeline for your hardware, such as enabling hardware acceleration, could help.

  2. Review Decoder Configuration and Latency:

    • The warning message suggests a potential issue with the decoder. Investigate if QGroundControl allows you to configure decoder settings, such as buffer sizes or latency parameters, which might help mitigate the issue. Reducing latency settings, if possible, could alleviate delays and freezing.

  3. Utilize GStreamer Tools for Debugging:

    • Use tools like gst-inspect-1.0 to examine the properties and capabilities of the GStreamer elements used in QGroundControl. This can help identify any misconfigurations. Testing different pipeline configurations with gst-launch-1.0 outside of QGroundControl might also improve performance.

  4. Ensure Hardware Acceleration:

    • Verify that your setup is using hardware-accelerated decoding, which can significantly enhance performance, especially if you’re using a Toradex module with a Video Processing Unit (VPU).

By following these steps, you should be able to identify and resolve the issues with RTSP streaming in QGroundControl. If the problem persists, further exploration of configuration options or testing with different versions of QGroundControl or GStreamer plugins might be necessary.
