Error installing PyGObject in window for running RTSP streaming.

Thank you @erik.
Still attempting will get back to you soon.

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

erik
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.

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

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

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 ?

jakaskerl 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.

Thank you @jakaskerl

I am assuming its not a bandwidth issue since it is connected pretty good industrial network infrastructure.

If Its processing, Is there any other way then lowering down resolution.

@erik .

Hi Erik.
Apart from the issues with FPS and resolution, I have an additional concern. I have disabled the TCP server on one device, leaving it in a bootable state. I am currently experimenting with gen2-RTSP. My objective is to have multiple scripts running for each camera to stream them individually to different endpoints. However, when I run the script for one device, I encounter difficulties streaming from the other device simultaneously. Below is the code I'm using:

#!/usr/bin/env python3

import threading

import gi
gi.require_version('Gst', '1.0')
gi.require_version('GstRtspServer', '1.0')
from gi.repository import Gst, GstRtspServer, GLib


class RtspSystem(GstRtspServer.RTSPMediaFactory):
    def __init__(self, **properties):
        super(RtspSystem, self).__init__(**properties)
        self.data = None
        self.launch_string = 'appsrc name=source is-live=true block=true format=GST_FORMAT_TIME ! h265parse ! rtph265pay name=pay0 config-interval=1 name=pay0 pt=96'

    def send_data(self, data):
        self.data = data

    def start(self):
        t = threading.Thread(target=self._thread_rtsp)
        t.start()

    def _thread_rtsp(self):
        loop = GLib.MainLoop()
        loop.run()

    def on_need_data(self, src, length):
        if self.data is not None:
            retval = src.emit('push-buffer', Gst.Buffer.new_wrapped(self.data.tobytes()))
            if retval != Gst.FlowReturn.OK:
                print(retval)

    def do_create_element(self, url):
        return Gst.parse_launch(self.launch_string)

    def do_configure(self, rtsp_media):
        self.number_frames = 0
        appsrc = rtsp_media.get_element().get_child_by_name('source')
        appsrc.connect('need-data', self.on_need_data)


class RTSPServer(GstRtspServer.RTSPServer):
    def __init__(self, **properties):
        super(RTSPServer, self).__init__(**properties)
        self.rtsp = RtspSystem()
        self.rtsp.set_shared(True)
        self.get_mount_points().add_factory("/oak63", self.rtsp)

        self.rtsp.send_data(data)

if __name__ == "__main__":
    import depthai as dai

    server = RTSPServer()

    pipeline = dai.Pipeline()

    FPS = 60
    colorCam = pipeline.create(dai.node.ColorCamera)
    colorCam.setResolution(dai.ColorCameraProperties.SensorResolution.THE_720_P)
    colorCam.setInterleaved(False)
    colorCam.setColorOrder(dai.ColorCameraProperties.ColorOrder.BGR)
    # colorCam.setIspScale(2,3)
    # colorCam.setFps(FPS)

    videnc = pipeline.create(dai.node.VideoEncoder)
    videnc.setDefaultProfilePreset(FPS, dai.VideoEncoderProperties.Profile.H265_MAIN)
    colorCam.video.link(videnc.input)

    veOut = pipeline.create(dai.node.XLinkOut)
    veOut.setStreamName("encoded")
    videnc.bitstream.link(veOut.input)

    desired_ip = "00.00.00.00
    device_infos = dai.DeviceBootloader.getAllAvailableDevices()
    device_info = [device_info for device_info in device_infos if device_info.name == desired_ip][0]
    if device_info:
        if device_info.protocol != dai.XLinkProtocol.X_LINK_USB_VSC:
            print("Running RTSP stream may be unstable due to connection... (protocol: {})".format(device_info.protocol))

        with dai.Device(pipeline, device_info) as device:
            encoded = device.getOutputQueue("encoded", maxSize=30, blocking=True)
            print("Setup finished, RTSP stream available under \"rtsp://localhost:8554/oak63\"")
            while True:
                data = encoded.get().getData()
                server.send_data(data)
    else
        print('No device found')

Further I haven't been able to figure out where am I loosing packages.
need your suggestion how can I achieve desired outcome which is having 60FPS with 1080 Resolution and running different script on different end point in single host.

Thank you very much.
