Get dimensions of a video file

Question

Is there a way in python to get the dimensions of a video file or some other library that would accomplish this? The equivalent of a Media Info or something? Th

Answer 1

There is a python module called pymediainfo - https://pypi.org/project/pymediainfo/ You can use this to get the required metadata of the media file.

Create a directory

mkdir supportfiles

For some reasons I install the module in target directory called "supportfiles"

pip install pymediainfo -t supportfiles/

To get the dimension/resolution of the video file

resolution.py

from supportfiles.pymediainfo import MediaInfo
media_info = MediaInfo.parse('/home/sathish/Videos/Aandipatti.mp4')

for track in media_info.tracks:
    if track.track_type == 'Video':
        print ("Resolution {}x{}".format(track.width, track.height))

Here is the output

[sathish@localhost test]$ python3.6 resolution.py 
Resolution 1920x1080

Just in case if you want to know the list of metadata attributes, Here is the solution

attributes.py

from supportfiles.pymediainfo import MediaInfo
media_info = MediaInfo.parse('/home/sathish/Videos/Aandipatti.mp4')
print(media_info.tracks)
for track in media_info.tracks:
    if track.track_type == 'Video':
        print(track.to_data().keys())
    elif track.track_type == 'Audio':
        print(track.to_data().keys())
    elif track.track_type == 'General':
        print(track.to_data().keys())
    else:
        print("No metadata present! or probably file corrupt!")

Here is the list of the attributes

[sathish@localhost test]$ python3.6 attributes.py
