If the preset transcoding templates of ApsaraVideo Media Processing (MPS) cannot meet your business requirements, you can create a custom transcoding template and configure the settings of the template, such as the encoding format, frame rate, and resolution. This topic provides examples on how to use MPS SDK for Java V2.0 to 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 the error message
The resource "Template" quota has been used upis reported when you create a template, your quota for template is used up. You can submit a ticket to apply for a higher quota.We recommend that you record the returned ID of the transcoding template that you create. You can also create a transcoding template and obtain its ID in the MPS console. For more information, see Transcoding templates.
