Synopsis¶

  list-channels
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

ServerValidation -> (string)

Check HTTPS server certificates. When set to checkCryptographyOnly, cryptography in the certificate will be checked, but not the server’s name. Certain subdomains (notably S3 buckets that use dots in the bucket name) do not strictly match the corresponding certificate’s wildcard pattern and would otherwise cause the event to error. This setting is ignored for protocols that do not use https.

Smpte2038DataPreference -> (string)

Specifies whether to extract applicable ancillary data from a SMPTE-2038 source in this input. Applicable data types are captions, timecode, AFD, and SCTE-104 messages. - PREFER: Extract from SMPTE-2038 if present in this input, otherwise extract from another source (if any). - IGNORE: Never extract any ancillary data from SMPTE-2038.

Specifies the color space of an input. This setting works in tandem with colorSpaceUsage and a video description’s colorSpaceSettingsChoice to determine if any conversion will be performed.

ColorSpaceUsage -> (string)

Applies only if colorSpace is a value other than follow. This field controls how the value in the colorSpace field will be used. fallback means that when the input does include color space data, that data will be used, but when the input has no color space data, the value in colorSpace will be used. Choose fallback if your input is sometimes missing color space data, but when it does have color space data, that data is correct. force means to always use the value in colorSpace. Choose force if your input usually has no color space data or might have unreliable color space data.
