Hi Folks,

I am using Hyperion NG on a Raspi 3B with Raspbian Buster and a Lightberry 4K (which is for some reason not available anymore). The last part in the processing flow of the Lightberry 4K is sending the signal through a UTV007 grabber, so this should be similar to a UTV007 that is connected to the Raspberry.

When I start running Hyperion NG, everything works fine, but after some minutes, I get strange artifacts in the grabbed video. I thought of this as a hardware issue, but (a) the Grabber does not show these artifacts when connected to a Windows PC running OBS and (b) if I hook up a PS Eye Webcam from a PS3 to the Raspi, I am getting no artifacts at all. Thus, it seems like a software issue between Hyperion and V4L2 (?)...

Here's a video of how the feed looks directly after starting hyperiond:

And this is what it looks like after some minutes:

Don't wonder - LEDs are shut off for now (but are wired to the Raspberry, WS2812b using SPI)

Where can I find the config file for hyperion ng, so I can post it? Apparently, there is no /etc/hyperion folder, while the /home/pi/hyperion is only a copy of the github repository (?)

Thanks for any advice

I know of no AV receiver capable of splitting a signal to FHD+4K. If a 4K device and a 1080p device are connected to the two outputs of a receiver, it only sends out 1080p to both outputs. I use the Lightberry 4K for this. It will work fine with 4K HDR (HDR10, not Dolby Vision though) and enable grabbing the signal using a USB cable hooked up to the Raspi. Thus, you only need one device instead of splitting, downscaling and converting digital to analogue.
