Hi,
I'm trying to overlay an image on different parts of a video. If I use a
single overlay command it will overlay the image for the time period I pass in.
However, when I create a command line for FFMPEG that should overlay the image
on the frames from 1-5 seconds and 10-20 seconds the command below fails with
the error "Cannot find a matching stream for unlabeled input pad 0 on filter
Parsed_overlay_1". I thought that filter chains take as input the previous
filter's output but obviously not how I have constructed it.
How can I overlay the video with a image at multiple offsets and varying
duration?
Thanks,
ffmpeg -i adpod.mkv -i output.bmp -filter_complex
"overlay=enable='between(t,1,5)'","overlay=enable='between(t,10,20)'" output.mp4
