# Live outputs: Supported codecs
<a name="codec-live-outputs"></a>

This table specifies the audio codecs that are supported in output groups that support live outputs.

Use this table if you identified a use case in [Output types for delivery to an AWS service](cc-outputs-aws.md) or [Output types for delivery to non-AWS destinations](cc-output-not-aws.md) and your output is live output. 

In the table, find the output group and container (if applicable) for the user case that you identified. Then read across to identify the video and audio codecs that are supported for that output group.
