Using Epiphan Video Grabbers to bring video into your Cisco Webex meeting

5webexciscoWe've been getting a lot of requests lately from our customers wanting to bring in full motion HD video into their Webex meeting. Sometimes it's to bring in the output from a HD camcorder, production switcher, NewTek TriCaste or even a Teradek Cube from a remote camera. In this solution brief Epiphan explains how you can do it.

Share an iPad screen during a Cisco WebEx Meeting

Cisco WebEx Meeting users know that sharing their desktop, laptop built-in camera, or virtual whiteboard is easy to do. But what if you need to share a tablet, mobile phone or some other device? Using Epiphan’s frame and video grabbers, you can share nearly any device during a WebEx Meeting. Share the screen from an iPad, iPhone, external camera, video game console, ultrasound display or nearly any other device with a video- out port. You can adapt this procedure to work with any other device by following the wired connection option.


  • A WebEx account (and knowledge of how to host or join a WebEx Meeting)
  • An Epiphan DVI2USB 3.0 or SDI2USB 3.0 video grabber
  • A device that has a video source you want to capture. The device must have a video-out port (e.g. HDMI, DVI, VGA, Component, SDI, etc) or a cable that converts to video out (e.g. an Apple Video adapter).
    Important Note
The DVI2USB/SDI2USB 3.0 uses power from the computer’s USB port and does not require any other power source or adapter.

For this particular example:

  • Apple iPad (2nd generation or newer running latest version of iOS)
  • An HDMI cable (if not using a VGA video adapter)
  • An Apple video adapter for your iPad (for a wired connection) OR
  • A 2nd or 3rd generation Apple TV (only required for wireless sharing of an iPad)

How to connect your iPad for use in a WebEx Meeting

You can connect your iPad both at least two ways, wired and wirelessly. Please read either of the two options as described below.

  • Option 1: Connect your iPad to a DVI2USB 3.0 video grabber using cables
  • Option 2: Connect your iPad to a DVI2USB 3.0 video grabber wirelessly using AirPlay and Apple TV

If you want to be able to move freely about, or it isn’t convenient to be tethered to the computer running the WebEx meeting, consider using this wireless method. The wireless setup may be subject to common issues that can affect wireless network connections, but in our testing it worked very well.

iPad Connections

  1. Before you start, ensure your iPad and Apple TV are running the latest updates and are both connected to the same wireless network.
  2. Install (if required) the Epiphan DVI2USB 3.0 capture software on your computer.
  3. Start the Epiphan Capture Tool (called VGA2USB on a Mac).
  4. On your Apple TV:
    1. Ensure that AirPlay is enabled and is connected to your wireless network.

  7. Use the provided USB 3.0 cable to connect your DVI2USB 3.0 to a USB port on your computer.NOTE:For best performance, use a USB 3.0 port. If no USB 3.0 port is available, a USB 2.0 port can be used.

How to share your iPad screen on a WebEx meeting

There are two methods for sharing an iPad in a WebEx meeting. If you’re not certain which will work best for your purpose, try them both prior to the meeting so you see the difference in appearance and quality. Ask a friend or colleague to join the test meeting to get an idea of the results for remote participants. The first method uses “Share My Desktop” to share the Epiphan Capture Tool with your meeting attendees. Generally the WebEx meeting uses a lower frame rate for desktop sharing. This is the simplest method and is perfect for showing low frame rate devices or applications. The second method uses “Start my Video” to share the feed incoming from the DVI2USB capture tool directly. WebEx Meetings tend to allocation higher bandwidth for video sharing, so this may be a better alternative if you want to show animations or movement on the screen. (The bandwidth allocation for video is set by your WebEx admin or service provider.)

  • Method 1: "Share My Desktop" option with WebEx Meetings
  • Method 2: "Start My Video" option with WebEx Meetings
