Imagen Live Connect 📕

💡 Pro tip: Imagen live connect requires a license. Your account manager will be happy to help with this

Introduction

Imagen offers the option to display and ingest live streams. Platform users may clip from live video, annotate media and timeshift (jump back through the feed). Imagen treats a live Stream as a piece of media, encoding a web proxy on the fly and creating a growing file.

The live streaming functionality processes streams up to 5Mbps (not full HD) and creates a 1Mbps version in real-time, from which users can make clips. After the event has ended, Imagen will re-encode the file to the platform's proxy quality.

Live streaming formerly relied on manual scheduling by our Client Services team. This new feature puts you in control.

Can I still use RTMP (Real-Time Messaging Protocol Stream)?

Yes. It is possible to use both RTMP and SRT, although SRT is far more reliable, faster and more secure.

💡Pro tip: Check out the SRT alliance for further info on the benefits of this protocol.

Configuration

Imagen captures your live streams using our scalable server farm, allowing you to create clips on the fly and choose a workflow for post-production.

To use a passphrase, simply add it to the end of the SRT URL as demonstrated below. Please keep this in mind that this must be alphanumeric and between 10 and 79 characters

Url:

This is the URL from which the stream will originate.

srt://[ip address or DNS]:[port]?mode=listener

Example:

srt://somelivestream.com:9999?mode=listener

Passphrase

srt://somelivestream.com:9999?mode=listener&passphrase={Passphrase goes here}

Supported SRT formats

SRT fully supports FFMPEG so the supported formats are the same as any other video on the platform. Check out our supported formats page for more info.

How it works

Now that your record has been created, Imagen will connect your new media object to the incoming SRT stream.

SRT is an open-source protocol that allows users to stream video and audio packets of information with AES encryption. The stream parameters, such as frame size, frame rate, and sample rate, will remain the same as the stream output. SRT is particularly effective on slower networks, as it adds a configurable degree of latency to the stream. This means that two SRT endpoints can receive, acknowledge, and resend packets of data that may have been lost on the slower network.

The following are two ways that devices can initiate the connection. They do not have any bearing on how data is transferred. each device can be configured to be a caller or listener.

Listener Mode

By setting the device to wait for the request to start. The listener device needs to know that it should listen to the SRT stream on a specific port.

Caller Mode

This mode sets the device to initiate the connection of the SRT stream.

What Next

As a workflow must be chosen before the stream begins, it may be worth looking at our workflows section if you are unfamiliar with or unsure which to choose. The workflow will

handle post-processing of your live stream
