o
Workaround: If using a computer with this host controller, use a different capture application
(like VLC), or upgrade to Windows 10.
l Windows 8.1 (with a Texas Instruments TSub USB 3.0 controller only): Audio capture fails with
WindowsCamera.
o
Workaround: If using a computer with this host controller, use a different capture application
(like VLC), or upgrade to Windows 10.
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 SDI’s USB 3.0 cable to the capture
computer.
l Windows 8.1/10 (with an Etron USB 3.0 controller only): Firmware update fails with an error message.
Retrying does not clear the message.
o
Workaround: Perform the firmware update on another computer (without an Etron USB host
controller) or using another USB port on the same computer. Note that USB 2.0 can be used for
firmware updates.
Affecting Mac
l It is not possible to capture from AV.io SDI 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.
l Audio capture isn't available using VLC on a Mac.
o
Workaround: If audio capture is needed, use another capture applicatin such as QuickTime.
l Sometimes video doesn't update (appears frozen) when using AV.io SDI as the video source for Skype
video calls.
o
Workaround: Disconnect and reconnect the video grabber. If the problem persists, try another
Mac computer or another communication tool. This problem appears to happen with regular
web cams as well.
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.
