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

This library seems to have an example that does just that on its main page (print_info(vs)):

http://code.google.com/p/ffvideo/

It's a wrapper around ffmpeg (there seems to be a few Python libraries for using ffmpeg).

Answer 2

How about using python-ffmpeg:

import ffmpeg
probe = ffmpeg.probe(movie_path)
video_streams = [stream for stream in probe["streams"] if stream["codec_type"] == "video"]

It gives you a very nice output like this:

>>> import pprint
>>> pprint.pprint(video_streams[0])

The only downside is that ffmpeg is required, but this should not be a problem in most of the cases.
