Extract delay between each GIF frame in Python












0















I am developing a program in Python which creates a video from an HTML file.
The HTML file may contain one animated GIF, and I need to keep the animation in the final video.



I already managed to extract each frame from the GIF, inspired by the method provided in the following GitHub Gist:



https://gist.github.com/revolunet/848913




import os
from PIL import Image


def extractFrames(inGif, outFolder):
frame = Image.open(inGif)
nframes = 0
while frame:
frame.save( '%s/%s-%s.gif' % (outFolder, os.path.basename(inGif), nframes ) , 'GIF')
nframes += 1
try:
frame.seek( nframes )
except EOFError:
break;
return True


extractFrames('ban_ccccccccccc.gif', 'output')



I replaced the GIF source in the HTML with each of these frames, and generated all the frames of the final video using PhantomJS.



Now, I need to get the duration of each frame in the source GIF file, in order to reproduce it in the corresponding frame of the video.



I found no way to achieve this in Python.
