User Manual

o
Workaround: Simply press the refresh icon to refresh the device list; only one AV.io HD device
now displays properly.
l Windows 8.1: Capturing using VLC media player occasionally results in repeated video frames causing
overlapping or teared frames to appear during capture (approximately 2% of the time).
o
Workaround: Avoid capturing on computers running Windows 8.1 or if that is not possible, use
different video capture software.
l Windows 8.1/10 (with an ASMedia ADM1042 A USB 3.0 controller only): Video capture fails when the
capture computer recovers from sleep mode, even if capture was stopped prior to sleep mode.
o
Workaround: Simply disconnect and re-connect AV.io HD’s USB 3.0 cable to the capture
computer.
l Windows 10 (64-bit): Capturing video with embedded audio using VLC media player or Windows
Camera can result in distorted audio capture.
o
Workaround: Capture on a computer with an OS different from Windows 10 (64-bit) or avoid
capturing using VLC and Windows Camera.
Affecting Mac
l It is not possible to capture from AV.io HD if a webcam is connected when using VLC media player 2.2.1
on a Mac (this is a VLC-specific bug).
o
Workaround: Disconnect the webcam, downgrade to an older version of VLC media player (ex:
2.1) or use a different capture application.
Affecting Ubuntu
l Ubuntu 14.04 LTS: With the exception of the first capture after system reboot, the very first captured
frame is always green.
o
Workaround: Remove the green frame in post-production editing. If streaming the captured
video, begin streaming after the initial green frame as already been captured.
l Ubuntu 14.14: Capturing using VLC media player occasionally results in repeated video frames causing
overlapping or teared frames to appear during capture (approximately 2% of the time).
o
Workaround: Avoid capturing on computers running Ubuntu 14.14. If that is not possible, use
different video capture software.
Affecting Chromebook
l Google Chrome OS v43.0.2357.125 (64 bit): When using Chromebook Apps Clipchamp and WebRTC,
AV.io HD is not detected as a valid audio device.
o
Workaround: Use Clipchamp and WebRTC for capturing video only, or use a different
Chromebook app to capture both video and audio, such as Screencastify or MediaCore Capture.
