Description
Summary of the bug:
How to reproduce:
I made a video with black at the beginning, middle and end, like this:
ffmpeg -f lavfi -t 5 -i color=black -target ntsc-dv black.dv
ffmpeg -f lavfi -t 5 -i color=red -target ntsc-dv red.dv
cat black.dv red.dv black.dv red.dv black.dv > colors.dv
Here is my terminal output:

This shows two black_starts at 0 and 10.01.
When I run with the -report flag I can see that blackdetect is finding the black frames at the end but the summary line that states when black starts and ends is not reported.
