Looking at the docs of libavfilter it doesn’t seem to be possible, but still, I hope you can help me.
I want to overlay an image to a movie but only for the last X seconds of the movie. I managed to overlay for the full movie, no problem. But can I get a time when the overlay is shown?
I use ffmpeg with compiled with libavfilter. Any tricks to solve this?
According to FFmpeg developer Stefano Sabatini, this cannot currently be done.
