cfn-resources: Stable

All classes with the Cfn prefix in this module (CFN Resources) are always stable and safe to use.

cdk-constructs: Experimental

The APIs of higher level constructs in this module are experimental and under active development. They are subject to non-backward compatible changes or removal in any future version. These are not subject to the Semantic Versioning model and breaking changes will be announced in the release notes. This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.

Amazon Interactive Video Service (Amazon IVS) is a managed live streaming solution that is quick and easy to set up, and ideal for creating interactive video experiences. Send your live streams to Amazon IVS using streaming software and the service does everything you need to make low-latency live video available to any viewer around the world, letting you focus on building interactive experiences alongside the live video. You can easily customize and enhance the audience experience through the Amazon IVS player SDK and timed metadata APIs, allowing you to build a more valuable relationship with your viewers on your own websites and applications.

This module is part of the AWS Cloud Development Kit project.

Channels

An Amazon IVS channel stores configuration information related to your live stream. You first create a channel and then contribute video to it using the channel’s stream key to start your live stream.

You can create a channel 

 Channel myChannel = new Channel(this, "Channel");

Importing an existing channel

You can reference an existing channel, for example, if you need to create a stream key for an existing channel 

 IChannel myChannel = Channel.fromChannelArn(this, "Channel", myChannelArn);

Stream Keys

A Stream Key is used by a broadcast encoder to initiate a stream and identify to Amazon IVS which customer and channel the stream is for. If you are storing this value, it should be treated as if it were a password.

You can create a stream key for a given channel 

 StreamKey myStreamKey = myChannel.addStreamKey("StreamKey");

Private Channels

Amazon IVS offers the ability to create private channels, allowing you to restrict your streams by channel or viewer. You control access to video playback by enabling playback authorization on channels and generating signed JSON Web Tokens (JWTs) for authorized playback requests.

A playback token is a JWT that you sign (with a playback authorization key) and include with every playback request for a channel that has playback authorization enabled.

In order for Amazon IVS to validate the token, you need to upload the public key that corresponds to the private key you use to sign the token. 

 PlaybackKeyPair keyPair = PlaybackKeyPair.Builder.create(this, "PlaybackKeyPair")
         .publicKeyMaterial(myPublicKeyPemString)
         .build();

Then, when creating a channel, specify the authorized property 

 Channel myChannel = Channel.Builder.create(this, "Channel")
         .authorized(true)
         .build();
