[FFmpeg-user] looping an animated gif

[Michael Koch]

Hello,

I want to overlay an animated gif over a video. The gif must be looped 
because it's much shorter than the video. I did try the "-loop 1" 
option, but I get the error message "Option loop not found". However, 
the loop option works fine for jpg images. How can an animated gif be 
looped?

ffmpeg -i background.MOV -loop 1 -i thumbsUp.gif -lavfi [0][1]overlay -t 
10 out.mp4

C:\Users\astro\Desktop>ffmpeg -i background.MOV -loop 1 -i thumbsUp.gif 
-lavfi [0][1]overlay -t 10 out.mp4
