Hello everyone,
i have a problem with my setup and i cannot find the mistake. maybe you guys can help me.
first off my setup:
1. rpi 3 b + raspbian stretch
2. ws2812b led (3 pwm)
3. level shifter
4. hdmi -> av -> usb grabber
My wiring:

Now to my problem: The LEDs wont start. what did i do:
1. blacklisted audio
2. edited config.txt
3. installed rpi_ws281x (git clone https://github.com/jgarff/rpi_ws281x)
4. installed scons
5. tested the leds (sudo PYTHONPATH=".:build/lib.linux-armv7l-2.7" python examples/strandtest.py)
5a. It works fine, the LEDs respond and show the test patterns. I tried this with and without the level shifter.
6. Tested the usb grabber. Shows video on rpi via mplayer.
For the first 5 Steps i used this guide (in german): https://tutorials-raspberrypi.…rgb-led-streifen-steuern/
Now i installed hyperion:
1. Installed hyperion via hypercon
2. adjusted the json file
3. start the service
Well and here comes the problem: The service starts, the grabber starts, but the LEDs wont start. (tested both with level shifter and without). When i stop the service (via hypercon), the LEDs flash white one time.
Here is my log:
