hyperion can't start with internal grabber and ws2812b

Hello to all!

Rpi3B+
OSMC
wb2812b 142 led

I am using ws2812b LEDs driving through Rpi3 pwm gpio18. The scheme is assembled correctly, because I can light the LEDs using the NeoPixel python example.

I want to use hyperion with the internal frame grabber, only with OSMC, but it does not start with my hyperion.config.json, writes an error: hyperion.service: Failed with result 'signal'.

Thank you, if you tell me what I'm doing wrong.
P.S. sorry for my English

Thanks for answer. I try this and many others methods, but everything did not work. I assemble a working scheme with arduino.
