OpenBSD video

I've been running 6.9-current recently - and what to check my webcam

wolf:fred ~: video -vf /dev/video0               
video device /dev/video0:
  encodings: yuy2
  frame sizes (width x height, in pixels) and rates (in frames per second):
	160x120: 30, 25, 20, 15
	176x144: 30, 25, 20, 15
	320x240: 30, 25, 20, 15
	352x288: 30, 25, 20, 15
	640x480: 30, 25, 20, 15
	1280x720: 9
  controls: brightness, contrast, saturation, hue, gain, gamma, sharpness, white_balance_temperature, backlight_compensation
Xv adaptor 0, GLAMOR Textured Video:
  encodings: yv12
  max size: 3286x1080
using yuy2 encoding
using frame size 640x480 (614400 bytes)
using default frame rate

which resulted in a green screen: I was about to ask misc@openbsd.org, and as I was going through my settings I looked at my /etc/sysctl.conf and saw kern.audio.record=1, which reminded me that I needed to:

sysctl kern.video.record=1

Security by default :~)

sysctlvideoOpenBSD
