System Information

OpenCV python version: 4.8.0.74
Operating System / Platform: Ubuntu 20.04
Python version: 3.8.10

Detailed description

Saving an image of shape 960, 1699, 3 gives shape 960, 1698, 3 (1699 vs 1698).

Steps to reproduce

import numpy as np
import cv2
writer = cv2.VideoWriter('res%02d.png', cv2.VideoWriter_fourcc(*'MJPG'), 1, (1699, 960))
writer.write(np.zeros((960, 1699, 3), np.uint8))
writer.release()
print(cv2.imread('res01.png').shape)

The reproducer also prints OpenCV: FFMPEG: tag 0x47504a4d/'MJPG' is not supported with codec id 7 and format 'image2 / image2 sequence' after line writer = cv2.VideoWriter('res%02d.png', cv2.VideoWriter_fourcc(*'MJPG'), 1, (1699, 960))

Also reproducible for C++ (tested commit 1794cdc).

Issue submission checklist

• I report the issue, it's not a question
