This topic provides examples on how to use ApsaraVideo for Media Processing (MPS) SDK for Go V2.0 to manage transcoding templates. For example, you can create, modify, delete, and query a transcoding template.
Prerequisites
An SDK client is initialized. For more information, see Initialize a client.
Create a transcoding template
You can call the AddTemplate operation to create a transcoding template.
Note
If an error
The resource "Template" quota has been used upis reported when you add a transcoding template, your quota for templates is used up. You can submit a ticket to apply for a higher quota.We recommend that you record the ID of a transcoding template. You can also create a transcoding template and obtain the transcoding template ID in the MPS console. For more information, see Transcoding templates.
