  • Error installing PyGObject in window for running RTSP streaming.

Hi @nikul ,
Unfortunately, running RTSP on the device itself wouldn't be possible, as this feature hasn't (and likely won't) be implemented on the RVC2-based devices.
BR, Erik

    Thank you for getting back @erik.
    I have one more question. Since have multiple camera. I want to run them on the same server. will I be able to run them through single script ?. having different endpoints or maybe different ports to access RTSP streaming.

    • erik replied to this.

        nikul Yep that should work, are you experiencing any issues with that approach?

            Hi @erik ,
            I am getting error while Flashing TCP on to the device.
            It is able to gain access of the device however when it trying to flash, it causing error occurs.
            same with device manager when I search in device manger I Have all of them available but when i click on it, device not found.

            Thank you

              Thank you.
              I do able to ping all the devices connected to the LAN.
              I specified the IP and remove application through GUI. and it worked temporary. i will look more into it.

              I have moved everything to lunux. for some reasons, streaming script is not working. By any chance will you be having idea if I may have missed some settings or anything else you want me to check.

              Thank you.

                Hi @nikul ,
                Without any context / screenshots / terminal outputs / logs / anything, we aren't able to help much.

                  Thank you for your prompt attention.

                  here the screenshot terminal and code snap.

                  Thank you.

                    My best guess is that the device doesn't have the TCP server running on it.

                      Thank you.
                      I believe IT has TCP server running since can access streaming through WSL but not from linux.

                          @jakaskerl can you help nikul debug this? My guess is the incorrect IP (mixing between host IP and WSL2 IP), or failing to set firewall for that port (if accessing from different machine).

                          nikul I believe IT has TCP server running since can access streaming through WSL but not from linux.

                          Could you once again try on WSL? Since you have stated:

                          I specified the IP and remove application through GUI. and it worked temporary. i will look more into it.

                          Perhaps there is no TCP stream running on the device anymore. Also make sure the device IP didn't change. If it did, you need to change the OAK_IP inside the RTSP server script.

                          Maybe check the firewall as well: sudo ufw status verbose. And Gstreamer: gst-launch-1.0 videotestsrc ! autovideosink

                          Let me know how it goes.

                          Thanks,

                            I tried on WSL it working fine. And unknowingly it now working in linux too.
                            However quality of the video fluctuate some time. Something like this

                            Hi @nikul
                            Few things to try:

                            • firewall: run sudo ufw disable and retry the script. Maybe the firewall is blocking some part of the stream.
                            • Make sure both versions of Gstreamer are the same
                            • Install necessary plugins if not already installed: sudo apt-get install gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly
                            • Ensure you have enough network bandwidth (try using ETH cable).
                            • Maybe switching to H264 would be better

                            Thanks,
                            Jaka

                              What you are seeing are h26x artifacts. If one frame gets missed, you will see this strange image until you get another keyframe (you can set frequency of that inside VideoEncoder node).
                              So a frame could get lost either from OAK to WSL server, or from WSL server (RTSP) to the RTSP client, best to first find that out, then look for causes on why that could happen (and how to mitigate it).

                              thank you for getting back.
                              I did try everything u mentioned issue is still the same.
                              While implementing H265_MAINgetting following error on terminal.

                              [rtsp @ 0x7f6524000cc0] method DESCRIBE failed: 503 Service Unavailable

                              rtsp://11.11.11.25:8554/OAK60: Server returned 5XX Server Error reply

                              Than you

                                Hi @nikul
                                As erik mentioned, check where the packets are getting lost.

                                1. OAK-RTSP server - instead of creating the server, you could just display the stream coming from OAK directly. If there is no packet loss, the error is likely with RTSP server streaming.

                                2. RTSP Server-Client, try sending random video/webcam stream with RTSP to see if the stream works as expected - no packet loss. Then you can check where the packet loss occurs with OAK.

                                Thanks,
                                Jaka

                                  I have figured out that 60 FPS with 1080P is what causing problem. However I can not compromise with 60FPS as it something crucial for the project i am working on. Any thoughts ?

                                      Hi @nikul

                                      nikul I have figured out that 60 FPS with 1080P is what causing problem

                                      So a bandwidth or processing issue? In both cases, can you afford to lower the resolution? Something like 720p should be much less (less than 50%) demanding.

                                      You would need to set the ISP scaling to 2/3 on the OAK device to achieve that since 720p native sensor resolution is not supported by depthai.

                                      Thanks,
