AVCAssistant(8) BSD System Manager's Manual AVCAssistant(8)NAME
AVCAssistant -- CoreMediaIO DAL Assistant Process.
DESCRIPTION
AVCAssistant is used by the CoreMediaIO Device Abstraction Layer Plug-In that provides audio/video capture from FireWire (IEEE 1394) AVC-
class devices (DV and HDV cameras and decks) using AVFoundation Capture APIs. The process allows multiple applications to simultaneously
capture from the same AVC device.

AUVITEK(4) BSD Kernel Interfaces Manual AUVITEK(4)NAME
auvitek -- Auvitek AU0828 video capture device driver
SYNOPSIS
auvitek* at uhub?
dtv* at dtvbus?
video* at videobus?
uaudio* at auvitek?
audio* at uaudio?
DESCRIPTION
The auvitek driver provides support for USB video capture devices based on the Auvitek AU0828 bridge. This hybrid analog/digital device
requires a hi-speed USB host controller (such as ehci(4)) to function properly.
For auvitek devices with analog audio capture interfaces, the uaudio(4) device driver provides access to the audio stream. Application soft-
ware can find a video(4) device's audio(4) device by comparing the VIDIOC_QUERYCAP bus_info field with the audio device's AUDIO_GETDEV config
field.
The following cards are supported by the auvitek driver:
Device Decoder Tuner
Hauppauge WinTV-HVR-850 au8522(4)xc5k(4)
Hauppauge WinTV-HVR-950Q au8522(4)xc5k(4)
Cards with an XC5000 tuner require the firmware provided by the pkgsrc/sysutils/xc5k-firmware package to function properly.
