AWS::IVS Construct Library
---

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your source code when upgrading to a newer version of this package.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
my_channel = ivs.Channel(self, "Channel")

You can use Advanced Channel type by setting the type property to
ivs.ChannelType.ADVANCED_HD or ivs.ChannelType.ADVANCED_SD.
Additionally, when using the Advanced Channel type, you can set
the preset property to ivs.Preset.CONSTRAINED_BANDWIDTH_DELIVERY
or ivs.Preset.HIGHER_BANDWIDTH_DELIVERY.
For more information, see Amazon IVS Streaming Configuration.
my_channel = ivs.Channel(self, "myChannel",
type=ivs.ChannelType.ADVANCED_HD,
preset=ivs.Preset.CONSTRAINED_BANDWIDTH_DELIVERY
)

If you want to use RTMP ingest, set insecureIngest property to true.
By default, insecureIngest is false which means using RTMPS ingest.
⚠ Note: RTMP ingest might result in reduced security for your streams. AWS recommends that you use RTMPS for ingest, unless you have specific and verified use cases. For more information, see Encoder Settings.
my_rtmp_channel = ivs.Channel(self, "myRtmpChannel",
type=ivs.ChannelType.STANDARD,
insecure_ingest=True
)

Importing an existing channel
You can reference an existing channel, for example, if you need to create a
stream key for an existing channel
my_channel = ivs.Channel.from_channel_arn(self, "Channel", my_channel_arn)

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
my_stream_key = my_channel.add_stream_key("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.
key_pair = ivs.PlaybackKeyPair(self, "PlaybackKeyPair",
public_key_material=my_public_key_pem_string
)

Then, when creating a channel, specify the authorized property
my_channel = ivs.Channel(self, "Channel",
authorized=True
)
