GMU Webcast Instructions

IMPORTANT: Webcast Set-Up and Testing
Instructions for Individual PCs and Webcasts Projected Using
LCD Projectors or Plasma Displays

To ensure that you can access the webcast, we URGE participants to run the Webcast Connection Test below at least a day in advance of the program.  If you are in a company environment, we urge you to request that your IT and A/V departments run the tests a day in advance with the same laptop / LCD projector, etc. that will be used for the actual webcastLast-minute set-up and testing is the primary reason for webcast viewing problems!

 

Test Your Connection

Pre-testing is recommended as some issues may be difficult to fix at the last moment and may require contacting your technical support department.  This may include confirming that your company's Internet Firewall supports streaming video.

Webcast Set-Up Instructions

Minimum system requirement
The system requirements vary for different versions.

  • Flash® - Please see the Adobe® download page and click on 'System Requirements' for the latest information.
  • Windows Media® - Please see the Windows Media® support page for the latest information.
  • Silverlight® - Some browsers (Firefox, Chrome, etc.) will use the Silverlight® player to display the video.  If you need to download the Silverlight® player, please go to www.silverlight.com.

Internet requirements
For best results, view the program over a broadband internet connection of 500 Kbps or above.  Please check with your IT department to ensure your network meets this minimum requirement.  You can also check your connection speed by going to:  http://speedtest.net/

Firewall requirement for networked office environments
Some corporate networks block live streaming media at their network firewall.  If you are unable to view the test link (above), your network/IT administrator may need to open ports on the firewall.   Please advise them that the following firewall ports need to be opened in order for you to view this webcast:  TCP: 80, 554 and 1755 and UDP: 554 and 1755. Additional, they should ensure that the computer level firewall is not blocking streaming media over port 80.

Playing a webcast through an LCD Projector
It is very important that prior to the webcast you test your webcast connection (see “Play a webcast test,” above) from your laptop through the actual LCD projector you will be using for the webcast itself. It is not uncommon for the webcast to play normally on the laptop but for the video to be blocked by a setting on the connected LCD projector.   Two common fixes for this issue are:

  • Uncheck the 'Use Overlays' Options in the 'Video Acceleration Settings' window of your windows media player.   From the Windows Media Player, go to:  Tools / Options / Performance / Advanced, then uncheck the box next to 'Use Overlays’.
  • Some computer systems are configured so that the Windows Media may only display on the output chosen as the PRIMARY device in the display properties (depending on the video codec). If you see a video playing on your PC's LCD screen but just a black box in the media window through the external output, change the external output to PRIMARY and your PC's LCD to secondary in the display properties.

However, quite often settings on the LCD projector itself need to be changed to view the streaming video.  Each projector has its own settings. Try to test an actual video stream prior to the event.

Troubleshooting

When I click the link to connect to the webcast, nothing happens or I have a black space where the video or video controls should appear.
Make sure that your computer has Adobe® Flash® Player®, Windows Media Player® or Silverlight® installed.  Click here to test your system/download players..

If you have Adobe® Flash® installed and are using Internet Explorer 9, but still cannot view the live stream, you will need to switch to "compatibility mode". To do so: Click "Tools" (If you do not see the menu hit the F10 key) > "Compatibility View" (A checkmark will now appear next to "Compatibilty View") > Refresh the page and the video should start working

When I click on the link the wrong video or program appears?
This may occur if your system or proxy server has cached a previous link. This may be resolved in one of two ways:

  • Refresh the page by hitting the F5 key while on the page or by holding down the 'Alt' 'Shift' and 'Ctrl' keys while simultaneously hitting the 'Refresh' button on the browser. You may need to do this several times.
  • Clear your systems cache in Internet Explorer: Internet Explorer b. Click on "Tools" on the menu at the top c. Click on "Internet Options" d. Under Browsing Options, Click on "Delete" e. Click on "Delete Temporary Internet Files" f. Click on "Close" g. Click on "OK"

The media player automatically stops or it continually stops and rebuffers
Press the "Play" button on to screen to restart the video stream. There are many variables that can affect streaming video over the internet.

 Network congestion can occur at any time due to the following problems:

  • You are trying to access an event during peak Internet traffic hours.
  • There is heavy traffic on your local computer network.
  • If you are connecting to the Internet from outside Northern America.  

Network congestion can be alleviated by: 

  • Upgrading to a faster connection. 
  • Minimizing the number of applications you are running during a webcast.

I get a picture but no sound
Make sure that your computer speakers are connected, turned on, and that you have adjusted the volume on the speaker volume knob and on your computer's volume control setting.  Also, make sure the computer's sound is not muted.

The video becomes choppy or freezes up (connectivity & firewall issues)
There is possibly an issue with your connection to the Internet (your Internet Service Provider or network connection is busy or having issues) or a firewall is causing problems.

If your player stops during the program, refresh / reload the Web page or press the start button on your player to initiate the webcast again.

  • If you are having difficulty with the audio or video stopping or experience excessive buffering / freezing, please try the following:  In Windows Media Player click Tools > Options> Performance.  Click on the dot beside the word "buffer" and increase the time in the box from 5 seconds to 10 to 20 seconds. Hit “Okay.”
  • If you are using the Firefox browser, you will need to download the free plug-in for Windows Media Player. Click here to download and install the plug-in.
