Application Viewing Requirements

The following are minimum requirements for end-users viewing the webcast:

Software Requirements

Unified Video Player is a custom media player developed and used by MediaPlatform. It utilizes both HTML5 <video> and Adobe’s Flash plugin as needed as the underlying browser technologies for playback. It has very robust support for mobile and desktop browsers and media formats including the ability to deliver video to the desktop without the use of the Flash Plugin (ie – using HTML5 Video). It is designed to support its full-feature set on the most popular browser and devices independent of the underlying player that is used. In fact, the underlying player that is used is completely transparent to the user. This document spells out which browsers and devices are supported and any limitations they may have. It also discusses the differences between desktop and mobile.

Streaming Protocol Support Matrix
A few things to note about the following support matrix:

  • HLS uses HTML5 Video (no Flash Plugin)
  • HDS and RTMP use the Flash Plugin
  • Operating Systems tested are Windows 7+ and OSX. Note that some browsers are not available on some operating systems.

Frequently Asked Questions (FAQ)

Login Issues

Q: The presentation start time has come and gone but I’m still seeing the lobby page.

A: Try refreshing your browser by pressing the F5 button on your keyboard or by clicking the Refresh button in the browser window.

Q: Nothing is happening when I press the “Play” button to view the presentation via the lobby page.

A: Turn off pop up blockers in your browser and try again.

Q: When I try to register for the webcast I get an error message saying that my email address is already registered.

A: If your email address is already registered, you should login to the webcast using that email address. There should be a link to login located on the same page with the registration form.

Q: Why can’t I get back to the registration page?

A: If you have already registered or signed in, you will be directed to the lobby page rather than to the registration page. To view the registration page again, you will need to clear your browser cookies, and then go to the registration page.

Presentation viewing issues

Q: Why is my video choppy?

A: The video may appear choppy due to network congestion. You may get a better connection by connecting to the presentation via another network.

Q: Why can’t I hear any audio?

A: Check to make sure your speakers are turned on and that the volume is at an appropriate level. Also check that the “mute” button is not selected in the video/audio window of the presentation.

Q: I can see and hear the presentation, but the slides are not flipping.

A: The slides may not be flipping because the presenter is not changing the slides. You can also try refreshing your browser if you think you should be seeing the slides change. Click F5 to refresh.

Q: I hear an echo while listening to the presentation.

A: Check to make sure that you don’t have two instances of the presentation window open on your computer. You may also be experiencing an echo if you are using Chrome as your browser. If this is the case, please close the Lobby window once the Presentation window opens.

Q: All of the presentation window content doesn’t fit on my screen.

A: You can press F11 on your keyboard to make the presentation full screen. For optimal viewing, the presentation should be viewed at a screen resolution of at least 1024×768 pixels. If your screen is not set to a lower resolution it may cut off portions of the presentation window.

Archive Viewing Issues
Q: When I select a slide index page in the archive, the presentation jumps back to the beginning rather than going to that slide.

A: Look at the timecode in the video/audio window of the archive. If it appears that there is no defined endtime for the video/audio, you will need to close the archive and try accessing it again. Once you have reloaded the archive, make sure that an endtime is visible on the timecode.
