Hi,
I'd like to use two instances of hyperion on the same Raspberry Pi (Raspbian) to control two different devices (WS2801 and Artnet).
I followed the steps described in this guide.
Both instances of hyperion are working fine alone, if the other one is not running at the same time.
If I try to run both instances I get the error message
Code
[hyperiond V4L2:/dev/video0] <ERROR> V4l2 init failed (VIDIOC_REQBUFS error code 16, Device or resource busy)
on the second instance I started. Clearly it means that the grabber can not be used by two instances at the same time so what do I have to do to get the grabbed pictures to the second instance of hyperion if I can not use the grabber a second times?
