There is a delay between when I select a slide as a Live Event administrator and when it appears on the viewer’s screen

When you select a slide, the slide synchronization information is embedded in the video stream itself. There is a built-in latency of about five seconds that is used for buffering the video stream (for smoother playback). When the video stream arrives at the viewer’s browser, Cisco Show and Share retrieves the slide indicated by the embedded information. So, although you might see a delay from when you select a slide from the admin console to when it appears on a viewer’s desktop, the delay applies to both the video and the slide. Viewers see the slide change at the correct time set by the administrator.

There is an error message when viewers without the QuickTime plugin attempt to view a live H.264 stream

The QuickTime plugin is used to decode H.264 live event streams in Cisco Show and Share. The system administrator can enable or disable the automatic download of the QuickTime plugin. When enabled, Cisco Show and Share attempts to download the plugin if it is not installed. When disabled, browsers without the plugin will receive an error message when attempting to view a live H.264 stream.

There is an error message when viewers without the Windows media plugin attempt to view a live WMV stream

Viewers should download and install the Windows media plugin prior to accessing a WMV stream.

When administering a DME live event, the Encoder Start button does not respond

If the encoder start button does not respond, physically check that the DME is stopped. If needed, manually stop the encoder. Then click Encoder Start and Broadcast Start to begin the live broadcast. (Only DME live events.)
