Response Structure
(dict) --
streamSession (dict) --
List of stream details.
channel (dict) --
The properties of the channel at the time of going live.
arn (string) --
Channel ARN.
authorized (boolean) --
Whether the channel is private (enabled for playback authorization). Default: false .
ingestEndpoint (string) --
Channel ingest endpoint, part of the definition of an ingest server, used when you set up streaming software.
latencyMode (string) --
Channel latency mode. Use NORMAL to broadcast and deliver live video up to Full HD. Use LOW for near-real-time interaction with viewers. Default: LOW . (Note: In the Amazon IVS console, LOW and NORMAL correspond to Ultra-low and Standard, respectively.)
name (string) --
Channel name.
playbackUrl (string) --
Channel playback URL.
recordingConfigurationArn (string) --
Recording-configuration ARN. A value other than an empty string indicates that recording is enabled. Default: "" (empty string, recording is disabled).
tags (dict) --
Array of 1-50 maps, each of the form string:string (key:value) .
(string) --
(string) --
type (string) --
Channel type, which determines the allowable resolution and bitrate. If you exceed the allowable resolution or bitrate, the stream probably will disconnect immediately. Default: STANDARD . Valid values:
STANDARD : Multiple qualities are generated from the original input, to automatically give viewers the best experience for their devices and network conditions. Resolution can be up to 1080p and bitrate can be up to 8.5 Mbps. Audio is transcoded only for renditions 360p and below; above that, audio is passed through.
BASIC : Amazon IVS delivers the original input to viewers. The viewer’s video-quality choice is limited to the original input. Resolution can be up to 480p and bitrate can be up to 1.5 Mbps.
endTime (datetime) --
UTC ISO-8601 formatted timestamp of when the channel went offline. For live streams, this is NULL .
ingestConfiguration (dict) --
The properties of the incoming RTMP stream for the stream.
audio (dict) --
Encoder settings for audio.
channels (integer) --
Number of audio channels.
codec (string) --
Codec used for the audio encoding.
sampleRate (integer) --
Number of audio samples recorded per second.
targetBitrate (integer) --
The expected ingest bitrate (bits per second). This is configured in the encoder.
video (dict) --
Encoder settings for video.
avcLevel (string) --
Indicates the degree of required decoder performance for a profile. Normally this is set automatically by the encoder. For details, see the H.264 specification.
avcProfile (string) --
Indicates to the decoder the requirements for decoding the stream. For definitions of the valid values, see the H.264 specification.
codec (string) --
Codec used for the video encoding.
encoder (string) --
Software or hardware used to encode the video.
targetBitrate (integer) --
The expected ingest bitrate (bits per second). This is configured in the encoder.
targetFramerate (integer) --
The expected ingest framerate. This is configured in the encoder.
videoHeight (integer) --
Video-resolution height in pixels.
videoWidth (integer) --
Video-resolution width in pixels.
recordingConfiguration (dict) --
The properties of recording the live stream.
arn (string) --
Recording-configuration ARN.

An S3 destination configuration where recorded videos will be stored.
bucketName (string) --
Location (S3 bucket name) where recorded videos will be stored.
name (string) --
Recording-configuration name. The value does not need to be unique.
state (string) --
Indicates the current state of the recording configuration. When the state is ACTIVE , the configuration is ready for recording a channel stream.
