Getting video dimension / resolution / width x height from ffmpeg

Question

How would I get the height and width of a video from ffmpeg\'s information output. For example, with the following output:

$ ffmpeg -i video.mp4         


        

Answer 1

without re module

out = error_message.split()               # make a list from resulting error string
out.reverse()
for index, item in enumerate(out):        # extract the item before item= "[PAR"
    if item == "[PAR":                      #
        dimension_string = out[i+1]          #
        video_width, video_height = dimension_string.split("x")

Edit: not a good answer because not all videos have that "PAR" information :(
