Configuration Requirements for Live Streaming
Last Updated: Jul 29, 2019 02:52PM EDT

This article applies to:  Echo360 Admins

Live streaming simply means that users can remotely watch a class as it is happening. For Live streamed classes, the input being captured by the capture appliance is webcast in real-time to those users viewing the Echo360 classroom.

For live streaming to work properly, there are a few fairly straightforward configuration requirements.

Live streaming is possible via captures generated by any capture appliance, including an SCHD, Echo360 Pro, Echo360 Pod, CCAP Installation, or Universal Capture Installation.

You can control the live stream in the same way you can control any scheduled capture, including stopping, pausing, or extending the capture. See Controlling Captures Through Device Login for further information and links.

Please note that if you are planning to use CCAP for Live streaming, review the information located in Using CCAP for Live Streaming.

Live streaming is only available for section captures

When you schedule a capture for a section, the Options available include a Live stream toggle. When you try to add or schedule a capture without selecting a section, you cannot enable this toggle.


Well, it has to do with the fact that users (students) can only access media that exists in a class. The view it by clicking the class and entering the classroom. So if you want people to view LIVE streams, it has to go into a class, in a section.

Remember also that to get into a section, you have to be assigned to the section. Meaning a user who isn't assigned to the section can't see the classes for the section, so they can't enter the classroom to view the media.

What you CAN do, however, is configure a dedicated course and section for holding special events or other happenings that you want to stream live to a larger institutional audience. Then assign yourself or another user as an Instructor and generate an Access Link to the section. You can configure this link to be for Registered Users only - so that only Echo360 users at your institution can view the Live Streams posted to this section. 

Check and configure outbound port communications

Live streaming is provided through hosted streaming (Wowza) servers. These servers receive the separate input streams from the appliance via RTP (real-time transfer protocol), then deliver the consolidated media stream back to users.

In order to make this work, the capture appliance needs to be able to communicate with the streaming servers through the appropriate ports, and those ports need to be configured, via wildcard DNS entries, to point to the cloud-based Wowza servers.

For details on this, see Port Configuration for LIVE Streaming.

Known Issue with NTSC and PAL sources for Live:

The live player provides video using the captured aspect ratio rather than the display aspect ratio.

NTSC and PAL analog video signals have square pixel display aspect ratios, however, because Echo360 appliances capture analog video using non-square pixels, there may be some noticeable differences for analog video sources as the captured aspect ratio is not a match for the display aspect ratio.

Analog Video Standard Display Aspect Ratio Captured Aspect Ratio HLS Live Player Note
NTSC 640x480 (4:3) 720x480 Video will appear slightly stretched horizontally (720 > 640).
PAL 768x576 (4:3) 720x576 Video will appear slightly squished horizontally (720 < 768).

This has no impact on digital sources.

This does not affect VOD playback of analog video as the Echo360 media processor converts those sources to the corresponding 4:3 square pixel display aspect ratio.
