Troubleshooting Williams Streaming Video

(If you're looking for information on creating new streaming media, see the documentation for the new Flash Media Server)

Williams uses a QuickTime Streaming Server to deliver video both on and off campus. Most of the time, viewing streamed video is straight forward. This troubleshooting guide is for when it isn't! The following list of solutions is arranged in order of increasing difficulty to use. The suggested approach to troubleshooting is to try the solutions in the order presented.

1) QuickTime Player
Several different players will work with the video stream that we broadcast, but we recommend using a recent version of the QuickTime player. Some of the more recently added videos will only work with QuickTime 7. If you don't have QuickTime, or have an older version, the latest version can be downloaded here http://www.apple.com/quicktime/download/standalone.html.

2) Windows Firewall
If you're using a Windows computer, it may be that the built-in firewall is restricting access to the streaming server. To check, click on the START button, select CONTROL PANEL, and open the WINDOWS FIREWALL control panel. A window opens up with three tabs. On the GENERAL tab, make sure that the box called "don't allow exceptions" has not been checked.

On the EXCEPTIONS tab, look for the name of the browser that you use, and make sure that there is a check mark next to it. In the example below, note that both Internet Explorer and Firefox are checked.

Note, of course, that any changes to the firewall should be made with caution!

3) Other Firewalls
If you're using a mac or a third-party firewall, you may need to adjust your firewall settings manually. The details of how to do this are specific to the firewall, however the ports that you will need to open are 554 outgoing and 6970-6999 incoming.

4) Router settings
If you're accessing a video from off-campus over a cable modem or DSL line, and you're using a wireless router or other router, you may need to instruct the router to allow "multicast streams". While the details of how to do this are specific to the particular make and model of router, and outside the scope of this guide, most routers provide a configuration page accessible using a web browser, and the setting for multicast streams will most likely be under the heading "IP settings " or "Advanced IP".

Below is a screen shot of the settings for one particular home router.

    Some audio applictions install and use custom audio playback devices. Open the Sound and Audio control panel and check to see if there is more than one option for audio playback device. If there is,changing the default audio playback device may fix QuickTime streaming audio problems.
