hyperion source from cam in front of tv - prepare input region

You dont need any programming skills, this is a build in hyperion functionality, it just needs to be configured, but i would not do it unless it is absolutely necessary as 2 devices are 2 times the hassle, configs and whatever, i would try to keep it as simple as possible.

Does anyone have any idea how I could run two hyperion instances and capture/process video from one rspi and send the data to another rspi running the LEDs? Thanks in advance

https://hyperion-project.org/w…-and-distributed-features NG is similar i guess

Any updates on the topic? I'm trying to set up hyperion.ng using rpi camera and while the normal one is working fine, I'm trying to position camera very close, use fisheye lens, and then correct it using the ffmpeg method and pass it to the grabber as /dev/video1 device but it does not work.
@Andrew_xXx any suggestions?

The method i posted only works with perspective correction and some simple lens correction if it is needed, for fisheye it is more complicated, but you can try other filters described here https://www.danielplayfaircal.…stortion-with-ffmpeg.html or here https://stackoverflow.com/ques…-ffmpeg/40659507#40659507

If u have some known camera with known lens parameters it is much easier, but it is more trail and error with individual fisheye lens u have so cant really provide any ready to go solution.

Also interested in this - wanted to try a , but not sure if it's all worth the effort.

Hi,

Thank you for the amazing write up, I was able to get v4l2loopback running along with ffmpeg which created /dev/video dummy stream, however, when I add /dev/video2 as a USB input in hyperion I get no live video stream in the preview window and no reaction from the LED lights. Any help is appreciated! I've been running through everything that could be wrong and just can't figure it out.

Side note, if you could include some attributes in the ffmpeg code to reduce the input/output video resolution/framerate to reduce cpu usage that'd be super helpful, I've scoured forums but everything always seems to result in an error or not actually doing anything.

Setup: Raspberry Pi Zero running Hyperbian

spikked28 unfortunately, I think this solution is bound for performance issues in any case Because ffmpeg conversion takes a very high toll on resources, even on a much beefier CPU like i7. I proposed an alternative here which measures perspective and lens distortions but only at calibration time, and so might work better in that regard: RE: Adjust Camera in Hyperion - Color - Help required
