Description
Hi!
I try to overlay the same scaled frame on each frame of my video:
ffmpeg -i Video.m2v -vf "split [out1] [out2]; [out2] scale=iw/4:ih/4 [patch1]; [out1] [patch1] overlay=20:50 [out]" -target pal-dvd -y Video_new.m2v
And I see that overlaying is late for one frame!
Log-file and screenshots of frames in attachment.
You can take any video with quick frame change and you will see.

Do you think this is a regression?

Confirmed with -vf (and -f lavfi -i testsrc as input) but not with -f lavfi.
I will be reworking the whole scheduling logic of filters, including vf_overlay. I'll keep in mind to check that particular case.

This is supposed to be fixed in current git head (and 1.0), please reopen if you can still reproduce the problem.
