        • 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 valid ARN value here both specifies the ARN and enables recording. Default: "" (empty string, recording is disabled).

            The endpoint to be used when streaming with IVS using the SRT protocol.

          • passphrase (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. Default: STANDARD. For details, see Channel Types.

          • s3 (dict) --

            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.

        • 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.

        • renditionConfiguration (dict) --

          Object that describes which renditions should be recorded for a stream.

          • renditionSelection (string) --

            Indicates which set of renditions are recorded for a stream. For BASIC channels, the CUSTOM value has no effect. If CUSTOM is specified, a set of renditions must be specified in the renditions field. Default: ALL.

          • renditions (list) --

            Indicates which renditions are recorded for a stream, if renditionSelection is CUSTOM; otherwise, this field is irrelevant. The selected renditions are recorded if they are available during the stream. If a selected rendition is unavailable, the best available rendition is recorded. For details on the resolution dimensions of each rendition, see Auto-Record to Amazon S3.

            • (string) --

        • 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 Best practices and strategies in Tagging Amazon Web Services Resources and Tag Editor for details, 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) --

        • 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.

          • resolution (string) --

            Indicates the desired resolution of recorded thumbnails. Thumbnails are recorded at the selected resolution if the corresponding rendition is available during the stream; otherwise, they are recorded at source resolution. For more information about resolution values and their corresponding height and width dimensions, see Auto-Record to Amazon S3. Default: Null (source resolution is returned).

          • storage (list) --

            Indicates the format in which thumbnails are recorded. SEQUENTIAL records all generated thumbnails in a serial manner, to the media/thumbnails directory. LATEST saves the latest thumbnail in media/latest_thumbnail/thumb.jpg and overwrites it at the interval specified by targetIntervalSeconds. You can enable both SEQUENTIAL and LATEST. Default: SEQUENTIAL.

            • (string) --

          • targetIntervalSeconds (integer) --

            The targeted thumbnail-generation interval in seconds. This is configurable (and required) only if recordingMode is INTERVAL. Default: 60.

            Important: For the BASIC channel type, 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.

      • startTime (datetime) --

        Time when the channel went live. This is an ISO 8601 timestamp; note that this is returned as a string.

      • streamId (string) --

        Unique identifier for a live or previously live stream in the specified channel.

      • truncatedEvents (list) --

        List of Amazon IVS events that the stream encountered. The list is sorted by most recent events and contains up to 500 events. For Amazon IVS events, see Using Amazon EventBridge with Amazon IVS.

        • (dict) --

          Object specifying a stream’s events. For a list of events, see Using Amazon EventBridge with Amazon IVS.

          • code (string) --

            Provides additional details about the stream event. There are several values; note that the long descriptions are provided in the IVS console but not delivered through the IVS API or EventBridge:

            • StreamTakeoverMediaMismatch — The broadcast client attempted to take over with different media properties (e.g., codec, resolution, or video track type) from the original stream.

            • StreamTakeoverInvalidPriority — The broadcast client attempted a takeover with either a priority integer value equal to or lower than the original stream's value or a value outside the allowed range of 1 to 2,147,483,647.

            • StreamTakeoverLimitBreached — The broadcast client reached the maximum allowed takeover attempts for this stream.

          • eventTime (datetime) --

            Time when the event occurred. This is an ISO 8601 timestamp; note that this is returned as a string.

          • name (string) --

            Name that identifies the stream event within a type.

          • type (string) --

            Logical group for certain events.
