Hello,
I’m trying to setup a usb camera inside docker container using ffmpeg platform. I have this config
camera:
- platform: ffmpeg
name: Corridor Camera 1
input: /dev/video0
When I run ffmpeg -i /dev/video1 -codec:v libx264 -qp 0 lossless.mp4 just after container restart, it makes a recording from this camera just fine, but when I add Picture Entity card with this camera it shows “Unavailable” and I have this errors in logs
