Metadict in ffmpeg does not have rotate information - opencv

Question

My aim is to extract frames out of a video but many times the frames are inverted. This is happening because "VideoCapture" in cv2 does read the rotate flag data present in the video metadata. I am running it on mac and installed "ffmpeg" package (5.0.1) using brew package manager. This is my code to check rotation present in a video using ffmpeg.
import ffmpeg
import cv2
import pprint
pp = pprint.PrettyPrinter(depth=4)
def check_rotation(path_video_file):
# this returns meta-data of the video file in form of a dictionary
meta_dict = ffmpeg.probe(path_video_file)
pp.pprint(meta_dict)
# from the dictionary, meta_dict['streams'][0]['tags']['rotate'] is the key
# we are looking for
rotateCode = None
if int(meta_dict['streams'][0]['tags']['rotate']) == 90:
rotateCode = cv2.ROTATE_90_CLOCKWISE
elif int(meta_dict['streams'][0]['tags']['rotate']) == 180:
rotateCode = cv2.ROTATE_180
elif int(meta_dict['streams'][0]['tags']['rotate']) == 270:
rotateCode = cv2.ROTATE_90_COUNTERCLOCKWISE
return rotateCode
Here the meta_dict is supposed to have information about the rotation but it is not there.
printing out meta_dict gives:

Can someone please help me to find if rotation is present in a video?
