How To Write On Video With Cv2 And Mtcnn? I'm Facing Problems With Fourcc

I'm trying to write a script that anonymized faces on videos. here is my code (python): import cv2 from mtcnn.mtcnn import MTCNN ksize = (101, 101) def decode_fourcc(cc): re

Solution 1:

I've changes this line:

video_out = cv2.VideoWriter(
    "mtcnn.mp4", cv2.VideoWriter_fourcc(*"mp4v"), fps, (width, height))

to:

video_out = cv2.VideoWriter(
    "mtcnn.avi", cv2.VideoWriter_fourcc(*'XVID'), fps, (width, height))

And now it works for me
