Publisher troubleshooting

Last Updated: Nov 06, 2015 10:28PM CET

When starting the publisher, Adobe Flash Player will ask for permission to access the camera and microphone.

Click Allow to grant access. If the publisher window remains white, or the Allow button can't be selected, see below for browser specific instructions.

Google Chrome

Additional confirmation required

When the publisher is used for the first time, Google Chrome needs an additional confirmation. Click Allow on the info bar that appears at the top of the browser.

Allowing access at a later stage

If you accidentally blocked camera access to SlideSync within Chrome, please follow these steps to allow access:

  • Click on the camera icon in the address bar
  • In the dialog that opens up, choose: Always allow to access your camera and microphone

Device selection

The device selection dialog offered by Chrome does not affect devices used by SlideSync.

Unable to locate available cameras

You may receive this message even if your camera is properly connected. We've found that a restart of Google Chrome usually solves this issue.

Image distortion

The preview shown by Chrome might be distorted in a way that the image consists of diagonal lines. To work around this you can use another browser, or disable the built-in version of Adobe Flash that is integrated with Google Chrome.

To disable the built-in version of Adobe Flash, follow these steps:

  1. Download Adobe Flash Player Plug-in
  2. Follow the instructions to install the plug-in
  3. Access chrome://plugins
  4. Click Details
  5. Locate Adobe Flash Player with type PPAPI

  6. Click Disable for this entry

MacBooks with Retina

Due to a bug in Adobe Flash Player, you may not be able to click the Allow button on newer MacBooks. The following steps provide a workaround for this issue.

  1. Go to the Website Privacy Settings panel for Adobe Flash Player. Note that the dialogue at the top of the page is the actual settings manager and not a screenshot.
  2. Click on and select Always allow.

  3. Close the Website Privacy Settings panel and reload the page.
