Unable to get RTSP feed with USB Cam #118

Open EduardoRonchi opened 2 years ago

EduardoRonchi commented 2 years ago

Hello, first of all thanks for this project!

I am using a Raspberry Pi 4 with a RPI Cam V2 and a thermal USB Camera (Lepton 3.5 + PureThermal Mini).

For the RPI Cam V2 it works fine, but when I try to use the USB Camera I cannot retrieve the RTSP stream.

Everything seems fine and similar to the RPI Cam V2, but I cannot get the stream.

image

I am using a simple python script the read the stream

import cv2
vcap = cv2.VideoCapture("rtsp://admin:admin@192.168.137.230:8000/h264")
while(1):
    ret, frame = vcap.read()
    cv2.imshow('VIDEO', frame)
    cv2.waitKey(1)

The output of this program is the following:

[rtsp @ 0x226dfd0] method DESCRIBE failed: 503 Service Unavailable
Traceback (most recent call last):
  File "rtsp_viewer.py", line 6, in <module>
    cv2.imshow('VIDEO', frame)
cv2.error: OpenCV(4.4.0) /tmp/pip-wheel-2l8ccy47/opencv-python/opencv/modules/highgui/src/window.cpp:376: error: (-215:Assertion failed) size.width>0 && size.height>0 in function 'imshow'

It seems that the image is None. But the same config works fine when changing the device (from /dev/video0 to /dev/video2) from the usb cam to the RPI Cam.

My rposConfig.json file:

{
  "NetworkAdapters" : ["awdl0","eth0", "wlan0", "en0"], 
  "IpAddress" : "192.168.137.230",
  "ServicePort" : 10000,

  "PTZOutputURL": "127.0.0.1:9999",
  "PTZCameraAddress": 1,
  "DeviceInformation" : {
    "Manufacturer" : "Raspberry Pi",
    "Model" : "4 B",
    "HardwareId" : ""
  },
  "logLevel" : 4, "logLevelComment": "## LogLevels are > 1:Error 2:Warning 3:Info 4:Debug",
  "logSoapCalls" : false
}

Any idea of what I am doing wrong? Note: The USB camera resolution is 160x120, it is a thermal camera. The camera is working, I can get the video by doing: ffplay /dev/video0

You are doing the right sort of things - RTSP type (in the config) is 3 for Gstreamer. You are right about the size.

RPOS calls a python script which makes the GStreamer pipeline. That tries to open /dev/videoN with a certain resolution. So I'd go poking about in the python program and find the lines where it makes the GStreamer launch string and just get it to open the v4l2 device without forcing a width and height. I had to do something similar here on my camera that only runs at 640x480 whereas the author of the USB component had a 1920x1080 HD USB camera.

just looked at the screen grab. It prints the gstreamer string on the screen and I can see it says "device=undefined" so it is not getting passed the right USB device path

EduardoRonchi commented 2 years ago

Ok, thanks! Ah, this printscreen is outdated. This “device=undefined” was due to the facts that I was using the RPI config file. When I updated the config file for the usbcam it shows the right device. I can’t post the image right now, but I’ll update here after. After changing the config file the output is the same, still can’t get the video stream.

Thanks!
