在 Kivy 应用程序中未播放 Gif 动画

问题描述

I am writing a kivy application, a game, which has an animated gif at the top which should play on a loop, as it does in finder etc. When it loads into the kivy gui it only shows one frame. I am new to kivy and would appreciate some help with this issue. I am using the .kv file to load the image:

    Image:
    source: 'spaceshipgif.gif'
    allow_stretch: True

I have studied the documentation on the kivy website and searched around but to no avail.

I don't remember exactly what the gif playing status is - they should work in principle, but some of our providers are better than others at it. As I remember it might work better if you compile kivy with PIL as the image provider. I think some of these problems can be caused by technically incorrect gif files, which aren't handled well by the default provider, but I'm not sure about this.

A better solution is to instead put the frames of the .gif as images in a zip file, and set the path to this zip as the image path in your widget. Kivy will automatically animate them for you, including making it easy to change the animation rate (or pause it), without being limited by problems with gif files.
