You don't have to provide a file, you can do $ ffmpeg -f lavfi -i testsrc -t 10 [...] -vf "your filter with expression here" -f null - As I think I mentioned: Only filters' arguments designed to use expressions will actually use them. And I still don't see the point of expressing "frames (or seconds) from the end", how do you plan to tell the expression what the end of the video is? Please help!
