Camera problem

Hi,
I reinstalled homeassistant after about a test and I’m stuck in getting camera working.
I use both a yi camera and a il Android webcam, i can see them from api/camera but not in my home overview.
What am I missing?

Here’s my camera configuration:

camera:

  • platform: yi
    name: Camera
    host: ‘192.168.100.14’
    password: XXXXXXXX
    ffmpeg_arguments: ‘-vf scale=800:450’
  • platform: ffmpeg
    input: http://192.168.100.15:8080/video
    name: FFmpeg
    extra_arguments: -q:v 2

I just tried with firefox and it’s OK… It seems a chrome related problem.
