@fspider All these YouTube live video URLs are working fine with vidgear, Kindly install and test testing branch by strictly following steps:

⚠️ This requires latest opencv-python or opencv-contrib-python binaries ( i.e. 4.1.1.26+)
installed on your machine. Install it from pypi as follows:

sudo pip install -U opencv-python

For more info., see issue #14 ⚠️

Firstly, Kindly clone and install the testing branch as follows:

git clone https://github.com/abhiTronix/vidgear.git
cd vidgear
git checkout testing
sudo pip install .
cd

Then use this example code with your URLs (https://www.youtube.com/watch?v=17Deeq8N2e4) as follows:

# import libraries
from vidgear.gears import CamGear
import cv2

stream = CamGear(source='https://youtu.be/17Deeq8N2e4', y_tube = True, logging=True).start() # YouTube Video URL as input

# infinite loop
while True:
	
	frame = stream.read()
	# read frames

	# check if frame is None
	if frame is None:
		#if True break the infinite loop
		break
	
	# do something with frame here
	
	cv2.imshow("Output Frame", frame)
	# Show output window

	key = cv2.waitKey(1) & 0xFF
	# check for 'q' key-press
	if key == ord("q"):
		#if 'q' key-pressed break out
		break

cv2.destroyAllWindows()
# close output window

stream.stop()
# safely close video stream.

and see if it works, if not, then report here. Goodluck
