can write video but the video can not be play

[sugizo]

Expected behaviour

can write and play video with sound using opencv

Actual behaviour

can write video using opencv
but the video can not be play
using IPython.display.video()

Steps to reproduce

!wget -c http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4
pip install -U opencv-python

• environment
  google colab

• example code taken from https://docs.opencv.org/4.x/dd/d43/tutorial_py_video_display.html
  already try to change the fourcc parameter into :
  DIVX, XVID, MJPG, X264, WMV1, WMV2,
  but still got the same result

import numpy as np
import cv2 as cv
import IPython

cap = cv.VideoCapture('BigBuckBunny.mp4')

# Define the codec and create VideoWriter object
fourcc = cv.VideoWriter_fourcc(*'XVID')
out = cv.VideoWriter('output.avi', fourcc, 20.0, (640,  480))

while cap.isOpened():
    ret, frame = cap.read()

    if not ret:
        print("Can't receive frame (stream end?). Exiting ...")
        break

    out.write(frame)

    if cv.waitKey(1) == ord('q'):
        break

# Release everything if job is finished
cap.release()
out.release()
cv.destroyAllWindows()

IPython.display.Video('output.avi', embed = True)

Issue submission checklist

• This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
• I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
• The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
• I'm using the latest version of opencv-python

5686 bytes is to small file size for the recorded video. Please ensure that you get valid frames from the original video for encoding.
Also OpenCV contains own implementation for mjpeg and it should always work, if you have jpeg enabled during OpenCV build (by default). To prove the assumption, you can use just static image and encode several frames with it.
