Hi!
I wolud be happy if someone could help me.
My problem is, that exactly the first 31 leds of my 2812b strip are flickering.
Everything is fine from 32th led.
I´m using:
Raspi 3b
WS281x Driver using the SPI Interface
HC74 Level shifter
Happy about an hint...
Thx
Andrew
Tested now hyperion.ng with raspi 3 using stretch where the grabber uses MPJG: Works out of the box 
Just some issues with the grabber itself because there is no USB 3.0 available - but I´d say: MJPG proof of concept: positive
I already had the topic on Github. I have no RPi 4 to narrow down the error. If I find something new I'll let you know.
The procedure from Github helped: Now running as a service and not from the console: the error disappears...
Should not be a problem.
Will do this task as soon as the new system is stable.
Hope at the weekend.
Can you help me with another issue?
Where does the webinterface (gui a port 8090) save its config?
Seems that I loose the config each i reboot 
First try worked
Have even a live picture in the Web-Interface.
Only Problem: i get a repeating Error when starting:
root@raspberrypi:/home/pi# hyperiond
[hyperiond DISPMANXGRABBER] <ERROR> Snapshot failed: -1
[hyperiond DISPMANXGRABBER] <ERROR> Previous line repeats 200 times
Any hints about this?
But the grabber seems to have a new driver in buster - its now YUVV instead of MJPG?
So the i´ve not tested the MJPG issue...

I´ve got a new RPI 4 this week, so I take the chance an will re-build my actual system which is running on a RPI 2.
I will install hyperion.ng on rasparian/debian buster and will to use the VBG500 Grabber (which only provides mjpg for pixelformat, but is usefull because it replaces HDMI-Splitter, PAL-Converter, Grabber from the PI 2 System to one single box).
This will take some days - but i will report the result here.
Hi,
I´m using a grabber with mjpg as single pixelformat option. I know that it wont work with the original hyperion installation.
Searching about this issue i found this thread.
My question to @Paulchen-Panther or someone else knowing about: Is the MJPG FPixelformat already available in the hyperion.ng master branch or still in a extra Branch by Paulchen-Panther? If so in which one?
Thx for help
Archie
