%% @doc This guide is intended for creating AWS Elemental MediaPackage
%% resources in MediaPackage Version 2 (v2) starting from May 2023.
%%
%% To get started with MediaPackage v2, create your MediaPackage resources.
%% There isn't an automated process to migrate your resources from
%% MediaPackage v1 to MediaPackage v2.
%%
%% The names of the entities that you use to access this API, like URLs and
%% ARNs, all have the versioning information added, like "v2", to
%% distinguish from the prior version. If you used MediaPackage prior to this
%% release, you can't use the MediaPackage v2 CLI or the MediaPackage v2
%% API to access any MediaPackage v1 resources.
%%
%% If you created resources in MediaPackage v1, use video on demand (VOD)
%% workflows, and aren't looking to migrate to MediaPackage v2 yet, see
%% the MediaPackage v1 Live API Reference.
%%
%% This is the AWS Elemental MediaPackage v2 Live REST API Reference. It
%% describes all the MediaPackage API operations for live content in detail,
%% and provides sample requests, responses, and errors for the supported web
%% services protocols.
%%
%% We assume that you have the IAM permissions that you need to use
%% MediaPackage via the REST API. We also assume that you are familiar with
%% the features and operations of MediaPackage, as described in the AWS
%% Elemental MediaPackage User Guide.

%% from an encoder such as AWS Elemental MediaLive. The channel receives
%% content, and after packaging it, outputs it through an origin endpoint to
%% downstream devices (such as video players or CDNs) that request the

%% that you spread out channels between channel groups, such as putting
%% redundant channels in the same AWS Region in different channel groups.
