Encode and decode .gif file to be used with pyglet and made into .exe with pyinstaller

I want to bake a .gif file into .exe with pyinstaller. From my research I have to encode the gif to a string and decode that string for this to be possible. Encoding the string and decoding the string is working. I get an error when trying to use it as a animation resource in pyglet. Something in the encoding-decoding has broken the gif? If there is another preferred way of doing this please let me know!

Step1

import base64

with open("test.gif", "rb") as imageFile:
    image = base64.b64encode(imageFile.read())
    print(image)

Step2

Saving this string in a .py file like this:

image = b'AWggsegsegs/....'

Step3

import pyglet
import base64
from gif_string import image


decodedgif = base64.b64decode(image) # Works this far
animation = pyglet.resource.animation(decodedgif) # Error here
sprite = pyglet.sprite.Sprite(decodedgif)

Error message reads

    identity = self._cached_animations[name]

  Ensure that the filename has the correct captialisation.

Instead of pyglet.resource.animation() which can only load files, you should use pyglet.image.load_animation(). Its optional File parameter supports file-like objects, so you should construct one using io.BytesIO() and pass it there.
