Firmware 1.0.13 release notes
Firmware 1.0.13 is a modest bug fix release that offers an improved video capture rate as well as a new online
format for the AV.io HD user guide.
What's new
This section provides details on the main features in firmware release 1.0.13.
Improved rate adjustment
AV.io HD now offers enhanced video capture in the form of smoothed frame rate adjustment when capturing
at a rate (e.g. 30 fps) different from that of the source (e.g. 24 fps).
AV.io HD web help
The AV.io HD user guide is now available in a convenient, searchable web help format! Look for it on Epiphan's
AV.io HD product page (http://www.epiphan.com/userguides/avio-hd/).
Limitations and Known Issues
This section includes known issues or limitations that affect functionality or usability and ways that you can
work around these limitations.
Affecting all operating systems
l Disconnecting and reconnecting the USB 3.0 cable on an AV.io HD device with an HDMI splitter halts
video capture.
o
Workaround: When possible, avoid this problem by not using a splitter. If a splitter is necessary,
disconnect both the USB 3.0 cable and HDMI splitter from the AV.io HD device, then first
reconnect the USB 3.0 cable before reconnecting the HDMI cable between AV.IO HD and the
splitter.
Affecting Windows
l Windows 7: The AV.io Config tool sometimes fails to display AV.io HD in the device list despite showing
up as an installed device on the computer’s Device Manager, therefore occasionally preventing
advanced configuration and firmware updates.
o
Workaround: Use AV.io Config on a different supported OS to configure AV.io HD. Firmware
updates and configuration changes are saved to the device. (Note that the AV.io HD device still
functions perfectly with the capture application on the original Windows 7 workstation despite
possible issues with the AV.io Config tool.)
l Windows 7/8.1: The AV.io Config tool may display the AV.io HD device more than once in the devicelist
possibly causing user confusion.
o
Workaround: Simply press the refresh icon to refresh the devicelist; 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 possibleto 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, downgradeto 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.
