[FFmpeg-user] encoding video from png diffs

Hello all,

So I know ffmpeg can encode video from a list of pngs. (img1.png, 
img2.png, img3.png, etc). But what if I have one png, and then a list of 
diffs (using vcdiff) like (img1.png, img2.diff, img3.diff, etc.). Each 
diff would be based upon the last. I could of course generate all the 
pngs, but it would take up a lot of space and I'm wondering if anyone 
knows of any creative way to do this? Thanks!
