Webcast Test System, With Quality Monitor Overlay
Quick Fix List
(1) Close your browser and reopen your browser, re-visit the event URL. Why? Functional elements/plugins, like the Adobe Flash Player might have crashed or become unstable, especially if the browser has been open for an extended period. A simple browser refresh can often solve the problem. This simple task solves most viewer issues.
(2) Close your browser and open another browser; re-visit the event URL. Why? Your browser’s security settings might inadvertently be blocking our player from loading and/or live media from being received. You could try looking through all your browsers security settings and resolving the issue yourself, or engage a local technical support resource to assist in troubleshooting. But, it’s easier sometimes to just use try another browser for the time being. Most browsers with default security settings will allow our player to load and play a live stream.
(3) Watch on your tablet or smartphone, connected over wifi or the cellular network. Why? One, your non-PC/Mac device uses different browsers and protocols for viewing a live stream, even when connected to the same wifi network. These alternative browsers and protocols (HTML5 oriented) provide another avenue for access that might not be blocked by a traditional PC/Mac browser or corporate firewall setting. Two, if you disconnect from the wifi network and use a cellular Internet, there are no corporate firewalls.

If live or on-demand video does not load/play, you may have a firewall issue. Using the link to the left you can conduct a firewall port test. The results of this test should be shared with the IT and network professional working to resolve accessiblity issues. If the results of this test show "success" on any port, you should be able to view this webcast video. [Success on any port does not guarantee the stream will play. If all the tests show failure, there is definitely a firewall blocking access to the video/stream.]
The above on-demand video might play while LIVE event video might not play. Live video is delivered slightly differently, and some corporate firewalls will block live streaming traffic. [Technical Note: Live streams are delivered using the RTMPT protocol which delivers RTMP via HTTP (Tunnelled). It requires slightly more bandwidth but is the best and only technique that can be used to work around firewalls blocking RTMP on ports 1935, 443 and 80. You can test protocols and ports below as needed.]
Quality Monitoring System Description
Please note: The HD stream will not play in the window above. To view the HD stream you need to view the stream full-screen, and your monitor must have a resolution of at least 720 x 1280 pixels.
How the Player Selects and Transitions Between Streams:
- Fits the bandwidth of the server » client connection.
As a viewer continues to watch the video, the player re-examines its decision (and might switch) in response to certain events:
- On a bandwidth increase or decrease, re-calculated at an interval of 2 seconds.
Framedrop is continuously monitored. Spikes are ruled out by taking 5-second averages. Once a quality level results in too large a framedrop, it will be blacklisted (made unavailable) for 30 seconds. After 30 seconds, it will be made available again, since the framedrop might be a result of a very decoding-heavy section in the video or external forces (e.g. the user opening Microsoft Office).
