hardware:
My Configuration:
MAKEFILE darknet:
changed the cfg and weights of darknet_video.py to yolov4 tiny, when running this script starts the camera and instantly freezes. If I close the WEBCAM tab several times the program comes back
follow the video showing this (I don’t know why the footage turned pink)
the lines that I changed in the code:
line 18: parser.add_argument(“–weights”, default=“yolov4-tiny.weights”,
line 24: parser.add_argument(“–config_file”, default=“./cfg/yolov4-tiny.cfg”,
line 178: cap = cv2.VideoCapture(“/dev/video0”)
code edited:darknet_video.py (6.6 KB)
even if i run the program without editing the same problem occurs.
Hi,
Could you try to read the camera with the below sample to see if it works?
from .camera import Camera
import atexit
import cv2
import numpy as np
import threading
import traitlets
class USBCamera(Camera):
capture_fps = traitlets.Integer(default_value=30)
capture_width = traitlets.Integer(default_value=640)
capture_height = traitlets.Integer(default_value=480)
capture_device = traitlets.Integer(default_value=0)
def __init__(self, *args, **kwargs):
super(USBCamera, self).__init__(*args, **kwargs)
try:
self.cap = cv2.VideoCapture(self._gst_str(), cv2.CAP_GSTREAMER)
show original
Thanks.
hello, I installed version 4.6 on SD to see if it worked, but it keeps freezing when starting darknet_video.py
so now I’m using version 4.6
To test the example I did:GitHub - NVIDIA-AI-IOT/jetcam: Easy to use Python camera interface for NVIDIA Jetson
output:
after:
didn’t work, so this example is written and testing with SD JetCard
“JetCam is tested on a system configured with the JetCard configuration. Different system configurations may require additional steps.”
I know the camera is working, the only problem is that it crashes when running the darknet example
I used this example on my PC and it worked normal, I think it must be some jetpack library that is causing it to freeze
Hi,
It looks like relates to the camera you used.
$ v4l2-ctl --list-formats-ext --all
Thanks.
I changed some program variables and it worked
thanks for the try
Good to know this.
