Hi,
I'm trying to set up hyperion.ng with an RPi camera that I want to position very close to the TV. All seems to be working fine OOTB latest 2.0.0-alpha.8 version. The only issue I have is the distortion because of the ultra-wide fisheye lens. I tried to correct it using v4l2loopback and ffmpeg as suggested here:
https://hyperion-project.org/t…on.2615/page-5#post-24418
but with no luck. Even if I create a /dev/video1 stream I cannot successfully switch hyperion to use it.
After running this command:
ffmpeg -re -i /dev/video0 -vf "perspective=382:127:1563:91:387:761:1495:986" -map 0:v -f v4l2 /dev/video1
I receive this error:
hyperiond V4L2:/DEV/VI : <ERROR> Throws error nr: VIDIOC_G_FMT error code 22, Invalid argument
Any suggestions on how that can be done efficiently?
