PIL: check if image is animated

Show all headers | View raw

[Multipart message — attachments visible in raw view] - view raw

Hello,

I am trying to check if an image is animated. I can't rely on the extension
as it may be a gif that's been renamed to .jpg or something else and is
still animated.

I thought that this used to work:

from PIL import Image


def check_animated(img):
    try:
        img.seek(1)
    except (EOFError):
        return 0
    return 1

img = Image('image.jpg')
print "animated?", check_animated(img)

Regardless if it's animated or not I get this exception:
ValueError: cannot seek to frame 1

I need to return 0 or 1, so excuse not using True or False.

Did the above get deprecated/change in a version at some point? Perhaps
there's something I missed during install (using PIP). Are there any other
ways to accomplish what I am trying to do, with or without PIL?

Python 2.7, linux
