Python Get Frame from Live Streaming

OpenCV comes with many powerful video editing functions. In current scenario, techniques such as image scanning, face recognition can be accomplished using OpenCV.

OpenCv library can be used to perform multiple operations on videos. Let’s try to do something interesting using CV2. Take a video as input and break the video into frame by frame and save those frame

# Importing all necessary libraries
import cv2
import os

# Read the video from specified path
# if source from file
# cam = cv2.VideoCapture("file.mp4")
# if source from rtsp
cam = cv2.VideoCapture("rtsp://admin:[email protected]:554/")

try:

	# creating a folder named data
	if not os.path.exists('data'):
		os.makedirs('data')

# if not created then raise error
except OSError:
	print ('Error: Creating directory of data')

# frame
currentframe = 0

while(True):

	# reading from frame
	ret,frame = cam.read()

	if ret:
		# if video is still left continue creating images
		name = './data/frame' + str(currentframe) + '.jpg'
		print ('Creating...' + name)

		# writing the extracted images
		cv2.imwrite(name, frame)

		# increasing counter so that it will
		# show how many frames are created
		currentframe += 1
	else:
		break

# Release all space and windows once done
cam.release()
cv2.destroyAllWindows()
