So I built a small Haswell system and resumed on my attempt at porting
OBS-Studio to OpenBSD.
I was able to do a short (silent) stream to twitch, so that tested out.
I am able to do window capture, so that seems ok.
The problems I am encountering involve audio capture (from a window/program or
from a mic) and video capture from webcam.
Audio:
I have a blue snowball
uaudio0 at uhub4 port 1 configuration 1 interface 0 "BLUE MICROPHONE
Blue
Snowball" rev 1.10/1.00 addr 6
uaudio0: audio rev 1.00, 2 mixer controls
audio1 at uaudio0
uhidev3 at uhub4 port 1 configuration 1 interface 2 "BLUE MICROPHONE
Blue
Snowball" rev 1.10/1.00 addr 6
uhidev3: iclass 3/0, 1 report id
uhid1 at uhidev3 reportid 1: input=15, output=15, feature=0
however…
sirjorj@ghost:~ audioctl -f /dev/audio1
audioctl: /dev/audio1: Device not configured
Does that mean that a) I need to configure this mic in mixerctl or b) OpenBSD
is unable to communicate with this mic?
I also tried this with the mic on a logitech webcam I have and got the same
result.
Also, in doing window capture (OBS uses Xcomposite), is there a way to capture
the audio for that window?
For the audio in general, is there a standard interface that OpenBSD surfaces
that OBS would connect to, or would the ‘right solution’ be to modify OBS
to use sndio?
Video:
I have a couple of different logitech webcams that I tried, but was unable to
get working. In fact, I noticed some inconsistencies with how OpenBSD
identified them.

When I connect my webcam (a Logitech Pro Webcam), i get the following
uvideo0 at uhub4 port 1 configuration 1 interface 0 "Logitech Logitech
Webcam
C930e" rev 2.00/0.13 addr 6
video0 at uvideo0
uaudio0 at uhub4 port 1 configuration 1 interface 2 "Logitech Logitech
Webcam
C930e" rev 2.00/0.13 addr 6
uaudio0: audio rev 1.00, 2 mixer controls
audio1 at uaudio0
Whenever I try to access it (OBS or ffmpeg directly), i get errors.

I’m guessing this means that the camera isn’t quite supported.
Thoughts?
