[Python] How to read exif data of movies in Python?

I use exifread (installed with python3 -m pip install exifread) to read EXIF tags from photos. The same camera takes videos with extension .MOV and a Create Date EXIF field that I am able to view with exiftool (installed with brew install exiftool):


$ exiftool DSC_0002.MOV | grep Date
File Modification Date/Time : 2020:02:20 18:13:14+00:00
File Access Date/Time : 2020:03:07 08:11:57+00:00
File Inode Change Date/Time : 2020:03:04 11:24:51+00:00
Modify Date : 2020:02:20 18:13:21
Track Create Date : 2020:02:20 18:13:21
Track Modify Date : 2020:02:20 18:13:21
Media Create Date : 2020:02:20 18:13:21
Media Modify Date : 2020:02:20 18:13:21
Create Date : 2020:02:20 18:13:15
Date/Time Original : 2020:02:20 18:13:15
Date Display Format : Y/M/D


I suppose exifread was built for photos, as the code below shows an empty list of tags for this video:

import exifread

f = open("/path/to/file", "rb")
tags = exifread.process_file(f)
print(tags)


One solution is to make a subprocess call to exiftool and parse the result:

EXIFTOOL_DATE_TAG_VIDEOS = "Create Date"
EXIF_DATE_FORMAT = "%Y:%m:%d %H:%M:%S"

cmd = "exiftool '%s'" % filepath
output = subprocess.check_output(cmd, shell=True)
lines = output.decode("ascii").split("\n")
for l in lines:
if EXIFTOOL_DATE_TAG_VIDEOS in l:
datetime_str = l.split(" : ")[1]
print(datetime.datetime.strptime(datetime_str,
EXIF_DATE_FORMAT))


How can I access the list of EXIF tags without a subprocess call?
