A python function utilising `ffprobe` to find any metadata related to a video file. Examples of what it can find include bitrate, fps, codec details, duration and many more. This gist returns the video height and width as an example.

#!/usr/local/bin/python3
import subprocess
import shlex
import json

# function to find the resolution of the input video file
def findVideoMetada(pathToInputVideo):
    cmd = "ffprobe -v quiet -print_format json -show_streams"
    args = shlex.split(cmd)
    args.append(pathToInputVideo)
    # run the ffprobe process, decode stdout into utf-8 & convert to JSON
    ffprobeOutput = subprocess.check_output(args).decode('utf-8')
    ffprobeOutput = json.loads(ffprobeOutput)

    # prints all the metadata available:
    import pprint
    pp = pprint.PrettyPrinter(indent=2)
    pp.pprint(ffprobeOutput)

    # for example, find height and width
    height = ffprobeOutput['streams'][0]['height']
    width = ffprobeOutput['streams'][0]['width']
    
    print(height, width)
    return height, width
