如何在媒体播放器（例如 MPV）中播放 opencv 帧？

Question

我只是定义窗口并在此脚本中播放视频，但如何通过媒体播放器而不是 opencv 播放视频？理想情况下，我会进行图像处理并能够在 mpv 中实时查看它。

#!/usr/bin/python

from cv2 import cv2


def main():
    
    def rescale_frame(frame, percent):
        width = int(frame.shape[1] * percent / 100)
        height = int(frame.shape[0] * percent / 100)
        dim = (width, height)
        return cv2.resize(frame, dim, interpolation=cv2.INTER_AREA)

    cap = cv2.VideoCapture("test.webm")

    while cap.isOpened():
        ret, frame = cap.read()
        rescaled = rescale_frame(frame, percent=50)
        if ret is True:
            cv2.imshow('Frame', rescaled)

            if cv2.waitKey(25) & 0xFF == ord('q'):
                break
        else:
            break

    cap.release()
    cv2.destroyAllWindows()


if __name__ == '__main__':
    main()
