Add logo to vlc video Raspberry

I try to set the crop function

  • Raspberry Pi OS 11 (bullseye)
  • vlc 3.VLC media player 3.0.16 Vetinari (revision 1.0.6-1682-g88158c836)
  • Raspberry PI 3b+
cvlc -f --crop=16:9 --video-filter=croppadd{cropbottom=0,cropright=0,croptop=0,cropleft=0} /home/pi/Desktop/video/MSC-00001.mp4 --sub-source logo --logo-file /home/pi/Desktop/logo/plogo-tv.png --logo-position 10 --no-osd

but it doesn’t appear.
but if I click ALT + C and then ALT + F after play it works and the logo appear…
why?

thanks
