Live Webcast FAQYou may be connecting to the Live Webcasting event through a network that has restrictions on the type of content that can be viewed. This can occur in any network environment from a home network to a large enterprise. In order to assure you have a pleasant webcast experience, we have created this document that addresses the common issues that a viewer might come across.
If you are signed up for a live event, BEFORE the event you should review this entire list of questions, requirements, and the solutions to the few problems you might encounter when accessing our live and archived content.
Have you run the Pre-event streaming test?
The MOST IMPORTANT step is to visit our Pre-Event Test stream. We begin live webcasting a Pre-Event Test video stream to your video player or live webcast portal which we build and deploy for you, 1 week prior to the event. This would be a sample webcast that uses all of the same technical requirements of the actual webcast.
Test your connection at this test page: Live Webcast Test - Webcasting Test Stream
If you can view video, hear the sound, and see the test slide, you will most likely be ready for the webcast. If there are issues you can run this Webcast System Test
If we are talking to you, we may ask you to copy and paste the results or show them to your IT department for further assistance.
Q. I cannot log into the event page or Live Webcasting media portal.
A: We develop and deploy branded secure live webcasting portals and video players for our client's webcasts. We provide password reset capabilities. If during an ICVDM Live Webcast a user cannot login. We ask first that they verify that they have access and are using the credentials they were given. If they still cannot access the webcast we provide a link located below the login area of the webcast entry page to retrive a forgotten password.
If the webcast included in-person attendance as well as online viewing our users may have received supplemental access to the live and/or archive site. When requested, we also provide user registration and management. Users may be required to go through the registration process.
Q. I am logged in, but I do not see video or hear audio.
A: The video streaming technology ICV Live Webcasting Service uses requires the following capabilities.
2) Flash or HTML5 video support
3) Network/firewall allowed for RTMP or HTTP video
4) Network/firewall allowed to receive HTTP traffic from Amazon.com & Akamai.com and LimeLight.com
If you are seeing a blank page that does not contain a video or slide window, your computer's security settings may be preventing these elements from displaying properly. Please check the following:
Adobe Flash: Adobe Flash Player Version 11 or better may need to be installed for your webcast to run. If you do not have Flash Player installed, or do not have the most current version, you should be prompted on the webcast page to install the latest available version of Flash Player. If you do not see this prompt, you can download the latest version here: http://get.adobe.com/flashplayer/
Be aware that your connection is location specific. If you perform a live webcast test from location "A" such as your home office, then attempt to view the live event from location "B", such as your business office, there is no certainty that you will meet with success. It is you or your organization's responsibility to perform a viewing test before the event. If you meet with any issues, please refer to the following checklist.
- A browser version of Internet Explorer 7.0 and higher or Firefox 44 or higher, Chrome 39 or higher
A note on browser incompatibility:
- IE 6.x may not support the RTMP streams we push out - basically new technology that old technology can't handle. We cannot support problems with IE 6.
- Possible remedy: upgrade browser version; try alternate browsers such as Firefox.
- Flash Player Version 11 or higher. If you have an older version, it would be best to upgrade now. It's free and does not require a reboot. http://get.adobe.com/flashplayer/
- Windows-based computer, Mac-based computer, Android phone or I-phone, Android tablet or iPad
- OPERATING SYSTEM: Windows 7+, Mac OS X 10.7+
- CPU: Single Core 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
- MEMORY: 2 gigabytes (GB) RAM (32-bit) or 4 GB RAM (64-bit)
- VIDEO: 32 bit video card
- BROWSERS: Mac: Safari 5+, Firefox 44+, Chrome 39+ (With Chrome on Mac you must use OSX 10.9 or better)
- BROWSERS: Windows: IE 7+, Firefox 45+, Chrome 42+ +, Safari 5+
- AUDIO: Speakers and a microphone – built-in or USB plug-in or wireless Bluetooth
Port Issues - Generally the streaming media comes in via port 80 and 1935. Many corporations close these ports to stop live streaming. These need to be opened to view the webcast.
Firewall Issues - Top tier Streaming Media Servers are provided by large companies that serve global corporate and fringe clients. Verify IT has not blacklisted the RTMP servers.
- Your firewall has to allow RTMP and HTTP via ports 80 and 1935
- Your firewall needs to allow Streaming Video as a service
- Your firewall needs to allow these domains and IP addresses below:
-- The specific IP address: 188.8.131.52
Social Networking Sites - Many companies block sites like YouTube and Facebook. Our Streaming video network provider supplies many of the web-based assets for social networking sites such as YouTube, Facebook and Instagram. If a company blocks YouTube, Facebook or Instagram, the webcast MAY be blocked.
Q: My audio or video freezes or stutters
A: There are a few possible factors that can cause this.
Bandwidth - When an end user is getting the feed, but video stutters and freezes, often times it is a bandwidth issue at the Internet provider. Most people are on cable, broadband or even DSL and just because they had bandwidth 10 minutes ago, as users come in and out of the system, this shared access is very volatile and the providers do not guarantee a set amount of bandwidth. Minimize unnecessary or excessive network traffic within your network and on your device by applications that access the web such as Dropbox when it is syncing.
Test your network bandwidth here: http://www.speedtest.net/ If the download result is less than 1500 Kbp/s (or 1.50 Mbp/s) then your connection may not be able to correctly play a live video feed of this nature with smooth playback, especially if it is a shared connection in an office.
Resources - There could be an application running that is consuming resources on your computer or there is a lack of bandwidth at your site. If you have other applications running on your PC, such as an indexer like Google Desktop, Spotlight or Dropbox, you should stop them.
Antivirus - If your antivirus application is running a scan, you should suspend that. Programs like McAfee and Avast and Norton can be set to restrict access to the technology used for webcasting. The difficulty here is that the stream may make it through the network but can get caught by a virus checker at the computer, and vice versa. Best to make sure virus scanners are disabled during the webcast. If possible, disable your antivirus application during the event.
Q: I can't see the video on my mobile device
Our webcasts can be typically be viewed on mobile devices running recent version of the Operating Systems for their respective devices. Playback and full functionality cannot however be supported, due to the customization each carrier, manufacturer and even uers perform on phones and tablets. These changes are device specific, and while we try to create a universally playable stream, some devices may not be compatible.
Also, mobile bandwidth can fluctuate extensively from location to location. Because this is a live streaming protocol, a consistent sustained data rate is required for the stream to play properly. Unlike video on YouTube and other services, that will progressively download the video, live video is constant and if bandwidth fluctuates below a minimum data rate, even for a couple of seconds, the stream could be interrupted.
