-- | Use the UpdatePipeline operation to update settings for a pipeline. When
-- you change pipeline settings, your changes take effect immediately. Jobs
-- that you have already submitted and that Elastic Transcoder has not started
-- to process are affected in addition to jobs that you submit after you
-- change settings.

-- | The optional ContentConfig object specifies information about the Amazon

-- and playlists: which bucket to use, which users you want to have access
-- to the files, the type of access you want users to have, and the storage
-- class that you want to assign to the files. If you specify values for
-- ContentConfig, you must also specify values for ThumbnailConfig. If you
-- specify values for ContentConfig and ThumbnailConfig, omit the
-- OutputBucket object. Bucket: The Amazon S3 bucket in which you want
-- Elastic Transcoder to save transcoded files and playlists. Permissions
-- (Optional): The Permissions object specifies which users you want to have
-- access to transcoded files and the type of access you want them to have.
-- You can grant permissions to a maximum of 30 users and/or predefined
-- Amazon S3 groups. Grantee Type: Specify the type of value that appears in
-- the Grantee object: Canonical: The value in the Grantee object is either
-- the canonical user ID for an AWS account or an origin access identity for
-- an Amazon CloudFront distribution. For more information about canonical
-- user IDs, see Access Control List (ACL) Overview in the Amazon Simple
-- Storage Service Developer Guide. For more information about using
-- CloudFront origin access identities to require that users use CloudFront
-- URLs instead of Amazon S3 URLs, see Using an Origin Access Identity to
-- Restrict Access to Your Amazon S3 Content. A canonical user ID is not the
-- same as an AWS account number. Email: The value in the Grantee object is
-- the registered email address of an AWS account. Group: The value in the
-- Grantee object is one of the following predefined Amazon S3 groups:
-- AllUsers, AuthenticatedUsers, or LogDelivery. Grantee: The AWS user or
-- group that you want to have access to transcoded files and playlists. To
-- identify the user or group, you can specify the canonical user ID for an
-- AWS account, an origin access identity for a CloudFront distribution, the
-- registered email address of an AWS account, or a predefined Amazon S3
-- group Access: The permission that you want to give to the AWS user that
-- you specified in Grantee. Permissions are granted on the files that
-- Elastic Transcoder adds to the bucket, including playlists and video
-- files. Valid values include: READ: The grantee can read the objects and
-- metadata for objects that Elastic Transcoder adds to the Amazon S3
-- bucket. READ_ACP: The grantee can read the object ACL for objects that
-- Elastic Transcoder adds to the Amazon S3 bucket. WRITE_ACP: The grantee
-- can write the ACL for the objects that Elastic Transcoder adds to the
-- Amazon S3 bucket. FULL_CONTROL: The grantee has READ, READ_ACP, and
-- WRITE_ACP permissions for the objects that Elastic Transcoder adds to the
-- Amazon S3 bucket. StorageClass: The Amazon S3 storage class, Standard or
-- ReducedRedundancy, that you want Elastic Transcoder to assign to the
-- video files and playlists that it stores in your Amazon S3 bucket.

-- | The ThumbnailConfig object specifies several values, including the Amazon

-- which users you want to have access to the files, the type of access you
-- want users to have, and the storage class that you want to assign to the
-- files. If you specify values for ContentConfig, you must also specify
-- values for ThumbnailConfig even if you don't want to create thumbnails.
-- If you specify values for ContentConfig and ThumbnailConfig, omit the
-- OutputBucket object. Bucket: The Amazon S3 bucket in which you want
-- Elastic Transcoder to save thumbnail files. Permissions (Optional): The
-- Permissions object specifies which users and/or predefined Amazon S3
-- groups you want to have access to thumbnail files, and the type of access
-- you want them to have. You can grant permissions to a maximum of 30 users
-- and/or predefined Amazon S3 groups. GranteeType: Specify the type of
