Hyperpixel and 1920 x 1920 content

we unsuccessfully try to use the square hyperpixel with the following command:

cvlc -f --no-audio --loop --play-and-exit --x11-display :0 /home/pi/Desktop/piplayer1/movies/picam1/* 2>> /home/pi/Desktop/piplayer1/error.log 1> /dev/null

is this impossible to do?

thanks for any hints…
