[FFmpeg-user] alternating two images

[Michael Koch]

Hello all,

let's assume I have two images and want to see them alternating with 
framerate 1.
image1, image2, image1, image2 and so on, and stop after 60 seconds.
I could make 60 copies of the images and rename them with numbers from 0 
to 59.
Is there an easier way to do this, without making so many copies?

Thanks,
Michael
