ApsaraVideo VOD:Transcoding templates

Usage notes

• In this example, an AccessKey pair is used to initialize a client instance.

• For more information about the request and response parameters of this operation, visit OpenAPI Explorer. You can click API Documentation in the top navigation bar to view information related to the API operation.

• This topic provides sample code only for some complex API operations. To obtain sample code for other API operations, perform the following operations: Visit Alibaba Cloud OpenAPI Explorer. In the left-side navigation pane, find the API operation whose sample code you want to obtain and specify the required parameters on the Parameters tab. Then, click Initiate Call. On the SDK Sample Code tab, select the language to view and download the sample code.

Initialize a client

Before you use the SDK, initialize a client. For more information, see Initialization.

Create a transcoding template group

You can call the AddTranscodeTemplateGroup operation to create a transcoding template group.

Click AddTranscodeTemplateGroup to learn more about this API operation.
