Simple ffmpeg wrapper for image2pipe which yields rawvideo frames from input video URL

Project description


I need to extract decoded frames from videos in order to feed DNN pipeline.

This is the answer package.


pip install image2pipe


from multiprocessing import Queue
import logging
import cv2

import image2pipe


q = Queue(maxsize=4)
decoder = image2pipe.images_from_url(q, "shuttle-flip.mp4", fps="30", scale=(1000, 556))

 for pair in yield_from_queue(q):
        fn, img = pair
        gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

        cv2.imshow("gray", gray)
