Set Up HLS Live Package Origin Endpoint for Low-Latency Delivery - Intelligent Media Services - Alibaba Cloud - Intelligent Media Services

Adds an origin endpoint configuration for a live streaming channel. This operation supports HLS, HLS_CMAF, and DASH protocols and DRM encryption.

Operation description

This operation allows you to create an origin endpoint for the live packaging service. The endpoint is used to configure back-to-origin settings, security policies (such as IP blacklists and whitelists and authorization codes), and time-shifting for a channel. Currently, only the HLS protocol is supported for playback. Before creating an origin endpoint, create a live packaging channel group and channel first. After the endpoint is created, the endpoint playback URL and other configuration details are returned.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
