hey there... I already finding how to adding logo to 5seconds before video with this:

Code:
ffmpeg -itsoffset 5 -i af.flv -r 25 -loop 1 -i bg.png -filter_complex "[1:v] fade=out:125:25:alpha=1 [intro]; [0:v][intro] overlay [v]" -map "[v]" -map 0:a -acodec copy out.mp4
but how to adding logo to end video?
Tried to search to google still not found solutions

Thanks
