System Requirements for Webcasts and Videos

Below are the computer system requirements to watch webcasts or recorded videos (video on demand) offered by CalEPA and its boards, departments, and offices.

Webcast Requirements

Webcasts are distributed using HTTP Live Streaming (HLS) for desktop and mobile clients.

Please try the test video stream in advance to verify that you will be able to watch a webcast.

Desktop Clients

Desktop clients include devices such as desktop computers or laptops that run desktop operating systems such as Windows or Mac OS. The requirements are:

  • A high-speed network connection such as DSL, cable or fiber.
  • You must have JavaScript enabled in your browser. JavaScript is usually enabled by default, but if the webcast is not playing check to make sure JavaScript is enabled.
  • The browsers supported for webcast playback are Microsoft Edge, Microsoft Internet Explorer version 11, Google Chrome, Mozilla Firefox and Apple Safari. See the JW Player website for the full rundown of supported browsers.
  • If you are using Microsoft Internet Explorer 11 on Windows 7 then you will also need the browser plug-in Adobe Flash Player 11.2 or a later version. You can check if Adobe Flash Player is installed here. The other supported browsers don't need Flash.

Mobile Clients

Mobile clients include devices that use a mobile operating system such as iOS or Android. The requirements are:

  • A high-speed mobile network connection such as 3G, 4G or most Wi-Fi connections.
  • iOS version 7.0 or later, or Android version 4.0 or later. Other mobile operating systems, such as Windows Phone, may be able to view these webcasts as well.

Video on Demand Requirements

Two different video formats are used for video distribution, which is indicated in or next to the link to the video.

MP4

  • A high-speed network connection such as DSL, cable or fiber.
  • You must have JavaScript enabled in your browser. JavaScript is usually enabled by default, but if the webcast is not playing check to make sure JavaScript is enabled.
  • The browsers supported for VOD playback are Microsoft Edge, Microsoft Internet Explorer version 11, Google Chrome, Mozilla Firefox and Apple Safari. See the JW Player website for the full rundown of supported browsers.
  • If you are using Microsoft Internet Explorer 11 on Windows 7 then you will also need the browser plug-in Adobe Flash Player 11.2 or a later version. You can check if Adobe Flash Player is installed here. The other supported browsers don't need Flash.

Windows Media Video (WMV)

  • A high-speed network connection such as DSL, cable or fiber.
  • Microsoft Windows Media Player. Other video players that can play Windows Media files include VLC Media Player (which has installers for Windows, Mac OS X and Linux) and Telestream Flip4Mac.
  • Videos are streamed using Windows Media Services, which require ports 554 (TCP, UDP) for RTSP and 1755 (TCP, UDP) for Microsoft Media Server (MMS, ms-streaming) to be open. Normally these ports will be open on the local network and users will be able to playback these videos. However, if you are experiencing problems connecting and are unsure about this requirement, please check with your Network Administrator.
