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.
    - insecureIngest (boolean) –
      
      Whether the channel allows insecure RTMP ingest. Default: false.
    - 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.
    - preset (string) –
      
      Optional transcode preset for the channel. This is selectable only for ADVANCED_HD and ADVANCED_SD channel types. For those channel types, the default preset is HIGHER_BANDWIDTH_DELIVERY. For other channel types ( BASIC and STANDARD), preset is the empty string ( "").
    - 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) –
      
      Tags attached to the resource. Array of 1-50 maps, each of the form string:string (key:value). See Tagging Amazon Web Services Resources for more information, including restrictions that apply to tags and “Tag naming limits and requirements”; Amazon IVS has no service-specific constraints beyond what is documented there.
      - (string) –
        
        (string) –
    - type (string) –
      
      Channel type, which determines the allowable resolution and bitrate. If you exceed the allowable input resolution or bitrate, the stream probably will disconnect immediately. Some types generate multiple qualities (renditions) from the original input; this automatically gives viewers the best experience for their devices and network conditions. Some types provide transcoded video; transcoding allows higher playback quality across a range of download speeds. Default: STANDARD. Valid values:
      - BASIC: Video is transmuxed: Amazon IVS delivers the original input quality to viewers. The viewer’s video-quality choice is limited to the original input. Input resolution can be up to 1080p and bitrate can be up to 1.5 Mbps for 480p and up to 3.5 Mbps for resolutions between 480p and 1080p. Original audio is passed through.
      - STANDARD: Video is transcoded: multiple qualities are generated from the original input, to automatically give viewers the best experience for their devices and network conditions. Transcoding allows higher playback quality across a range of download speeds. 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. This is the default when you create a channel.
      - ADVANCED_SD: Video is transcoded; multiple qualities are generated from the original input, to automatically give viewers the best experience for their devices and network conditions. Input resolution can be up to 1080p and bitrate can be up to 8.5 Mbps; output is capped at SD quality (480p). You can select an optional transcode preset (see below). Audio for all renditions is transcoded, and an audio-only rendition is available.
      - ADVANCED_HD: Video is transcoded; multiple qualities are generated from the original input, to automatically give viewers the best experience for their devices and network conditions. Input resolution can be up to 1080p and bitrate can be up to 8.5 Mbps; output is capped at HD quality (720p). You can select an optional transcode preset (see below). Audio for all renditions is transcoded, and an audio-only rendition is available.
      Optional transcode presets (available for the ADVANCED types) allow you to trade off available download bandwidth and video quality, to optimize the viewing experience. There are two presets:
      - Constrained bandwidth delivery uses a lower bitrate for each quality level. Use it if you have low download bandwidth and/or simple video content (e.g., talking heads)
      - Higher bandwidth delivery uses a higher bitrate for each quality level. Use it if you have high download bandwidth and/or complex video content (e.g., flashes and quick scene changes).

      Encoder settings for video.
      - avcLevel (string) –

      - 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) –

        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.
    - recordingReconnectWindowSeconds (integer) –
      
      If a broadcast disconnects and then reconnects within the specified interval, the multiple streams will be considered a single broadcast and merged together. Default: 0.
    - state (string) –
      
      Indicates the current state of the recording configuration. When the state is ACTIVE, the configuration is ready for recording a channel stream.
    - tags (dict) –
      
      Tags attached to the resource. Array of 1-50 maps, each of the form string:string (key:value). See Tagging Amazon Web Services Resources for more information, including restrictions that apply to tags and “Tag naming limits and requirements”; Amazon IVS has no service-specific constraints beyond what is documented there.

        (string) –
    - thumbnailConfiguration (dict) –
      
      A complex type that allows you to enable/disable the recording of thumbnails for a live session and modify the interval at which thumbnails are generated for the live session.
      - recordingMode (string) –
        
        Thumbnail recording mode. Default: INTERVAL.
      - targetIntervalSeconds (integer) –
        
        The targeted thumbnail-generation interval in seconds. This is configurable (and required) only if recordingMode is INTERVAL. Default: 60.
        
        Important: Setting a value for targetIntervalSeconds does not guarantee that thumbnails are generated at the specified interval. For thumbnails to be generated at the targetIntervalSeconds interval, the IDR/Keyframe value for the input video must be less than the targetIntervalSeconds value. See Amazon IVS Streaming Configuration for information on setting IDR/Keyframe to the recommended value in video-encoder settings.
