-- 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.
cp1ContentConfig :: Lens' CreatePipeline (Maybe PipelineOutputConfig)

-- transcode.
cp1InputBucket :: Lens' CreatePipeline Text
cp1InputBucket = lens _cp1InputBucket (\s a -> s { _cp1InputBucket = a })

-- | The name of the pipeline. We recommend that the name be unique within the AWS
-- account, but uniqueness is not enforced.
--
-- Constraints: Maximum 40 characters.
cp1Name :: Lens' CreatePipeline Text
cp1Name = lens _cp1Name (\s a -> s { _cp1Name = a })

-- | The Amazon Simple Notification Service (Amazon SNS) topic that you want to
-- notify to report job status.
--
-- To receive notifications, you must also subscribe to the new topic in the
-- Amazon SNS console.   Progressing: The topic ARN for the Amazon Simple
-- Notification Service (Amazon SNS) topic that you want to notify when Elastic
-- Transcoder has started to process a job in this pipeline. This is the ARN
-- that Amazon SNS returned when you created the topic. For more information,
-- see Create a Topic in the Amazon Simple Notification Service Developer Guide.
-- Completed: The topic ARN for the Amazon SNS topic that you want to notify
-- when Elastic Transcoder has finished processing a job in this pipeline. This
-- is the ARN that Amazon SNS returned when you created the topic.  Warning: The
-- topic ARN for the Amazon SNS topic that you want to notify when Elastic
-- Transcoder encounters a warning condition while processing a job in this
-- pipeline. This is the ARN that Amazon SNS returned when you created the topic.
-- Error: The topic ARN for the Amazon SNS topic that you want to notify when
-- Elastic Transcoder encounters an error condition while processing a job in
-- this pipeline. This is the ARN that Amazon SNS returned when you created the
-- topic.
cp1Notifications :: Lens' CreatePipeline (Maybe Notifications)
cp1Notifications = lens _cp1Notifications (\s a -> s { _cp1Notifications = a })

-- | The Amazon S3 bucket in which you want Elastic Transcoder to save the
-- transcoded files. (Use this, or use ContentConfig:Bucket plus
-- ThumbnailConfig:Bucket.)
--
-- Specify this value when all of the following are true:  You want to save
-- transcoded files, thumbnails (if any), and playlists (if any) together in one
-- bucket. You do not want to specify the users or groups who have access to the
-- transcoded files, thumbnails, and playlists. You do not want to specify the
-- permissions that Elastic Transcoder grants to the files. When Elastic
-- Transcoder saves files in 'OutputBucket', it grants full control over the files
-- only to the AWS account that owns the role that is specified by 'Role'.  You
-- want to associate the transcoded files and thumbnails with the Amazon S3
-- Standard storage class.
--
-- If you want to save transcoded files and playlists in one bucket and
-- thumbnails in another bucket, specify which users can access the transcoded
-- files or the permissions the users have, or change the Amazon S3 storage
-- class, omit 'OutputBucket' and specify values for 'ContentConfig' and 'ThumbnailConfig' instead.
cp1OutputBucket :: Lens' CreatePipeline (Maybe Text)
cp1OutputBucket = lens _cp1OutputBucket (\s a -> s { _cp1OutputBucket = a })

-- | The IAM Amazon Resource Name (ARN) for the role that you want Elastic
-- Transcoder to use to create the pipeline.
cp1Role :: Lens' CreatePipeline Text
cp1Role = lens _cp1Role (\s a -> s { _cp1Role = a })

-- | The 'ThumbnailConfig' object specifies several values, including the Amazon S3
-- bucket in which you want Elastic Transcoder to save thumbnail files, 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 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. 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 thumbnail
-- files. 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 thumbnail files that
-- Elastic Transcoder adds to the bucket. Valid values include:   'READ': The
-- grantee can read the thumbnails and metadata for objects that Elastic
-- Transcoder adds to the Amazon S3 bucket.  'READ_ACP': The grantee can read the
-- object ACL for thumbnails that Elastic Transcoder adds to the Amazon S3
-- bucket.   'WRITE_ACP': The grantee can write the ACL for the thumbnails that
-- Elastic Transcoder adds to the Amazon S3 bucket.  'FULL_CONTROL': The grantee
-- has 'READ', 'READ_ACP', and 'WRITE_ACP' permissions for the thumbnails 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 thumbnails that it stores in your Amazon S3
-- bucket.
