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
