3.10. Troubleshooting#

3.10.1. I started the GStreamer on the host computer, but the image is not shown.#

  • Please make sure that you set the correct port value in your GStreamer settings.

  • You may use wireshark or tcpdump to check if the UDP packet is transmitted to the host computer.

    To check if the image packet reaches to the host computer, please use the command below.

    sudo tcpdump -i eth0 dst port 5004

    The command above dumps the packets that reaches to the port 5004 of eth0.

  • You may check if the image output process is working by using the command below in the GMSL2-10GbE conversion module.

    pidof v4l2-ctl

    There should be the process ID output depends on the number of working deserializer.

3.10.2. There is an image artifact when I connect multiple cameras with the same deserializer port#

In case you see images similar to the reference site, please try to set the kernel parameter as follows on the host PC.

sudo sysctl -w net.core.rmem_default=33554432
sudo sysctl -w net.core.rmem_max=33554432
