PiCam as Source for V4l2

Hello

is it posible to use a PiCam directly connected with a pi Zero as hyperion Video Source
i tried it, but become always this Error:

V4L2GRABBER INFO: width=640 height=480
terminate called after throwing an instance of 'std::runtime_error'
what(): V4L2GRABBER ERROR: Only pixel formats UYVY, YUYV, and RGB32 are supported ERROR

the PiCam Works fine with: raspistill -o /home/pi/testbild.jpg or with raspivid

i tried to change the output format with
--pixel-format

but the Version of hyperion 1.03 dont know this parameter!

but I found my First Problem:

I use the Parameter --pixel-format false

i used -pixel-YUYV and not --pixel-format -YUYV

sorry, i am not so good with Linux!
i have to Check it at home

sudo hyperion-v4l2 -d /dev/video0 --video-standard "no-change" --pixel-format "uyvy" --screenshot

hyperion-v4l2:
