I was able to test it on Sunday and it works great now! The capture is detected as 1280x960 and with a size dec of 4 it looks fantastic and only using 30-40% of CPU on a RPi 3b. Using the external cam for capture, it is independent of source, so all 4k/HDR content is viable.

Will those changes be rolled into the main branch?

If there's anything I can do to help out with testing or documenting I'm happy to do so, just let me know how I can help out.

Thanks for your work on this, I really appreciate it!!!

I used the instructions on github, from my history:

18 sudo apt update
19 sudo apt upgrade
20 sudo apt-get install git cmake build-essential qtbase5-dev libqt5serialport5-dev libusb-1.0-0-dev python3-dev libxrender-dev libavahi-core-dev libavahi-compat-libdnssd-dev libjpeg-dev
21 sudo apt-get install libraspberrypi-dev
22 wget -qO- https://raw.githubusercontent.….ng/master/bin/compile.sh | sh
23 cd ~/hyperion/build
24 sudo make install/strip

then just ran hyperiond from command line to test before installing service.

Well, fine in motion at 1280x720, so that would lead me to believe the camera is recognized correctly by the RPi, and getting the appropriate power. So I'm not sure why the grabber is detecting the dimensions wrong/setting them to that resolution. Thoughts?

Hi Paulchen,

Yeah, that's the behavior I would expect, however I can set the resolution and whenever I call hyperion-v4l2 it resets the format back to 160x120:
I'm installing 'motion' now to see if it works under that at a real resolution.

Hi All,

I've been using Hyperion for years and have a working classic setup with HDMI2AV on an older TV, and just recently purchased a new 4k.

On the new one I went with RPi3B, WS2812spi, and Hyperion.ng - all of which appears to be working fine, but running into the same issues of HDR washout, etc... that everyone else sees when using converters/splitters and a USB AV Cap dongle. So decided to try out the USB camera solution as discussed in this thread: https://hyperion-project.org/t…repare-input-region.2615/

Had a Logitech C270 already, so the setup was pretty straight forward and largely works, but strangely the NG version of hyperion-v4l2 will only capture at 160x120, even with no screen decrementing. Even setting the resolution with v4l2-ctl before running it has no effect, because it seems to just get set back whenever hyperion-v4l2 runs:

pi@raspberrypi:~ $ v4l2-ctl -v width=640,height=480

Signal detection informations
=============================

signal detection area  : 40,30 x 120,90


WARNING "no signal image" is to dark, signal detection is not relaiable.
WARNING difference between threshold color and the other color components is to small, signal detection might have problems.

Since it looks like the latest hyperion-v4l2 no longer supports setting width/height, I'm at a loss on how to crack this. Not sure if it's a bug or just me missing something simple. Any ideas?
