Step 1: Identify the output group types for the downstream system

The first step in planning any AWS Elemental MediaLive workflow is to determine which types of output groups you need to produce, based on the requirements and capabilities of the systems that are downstream of MediaLive.

Perform this work with the downstream system before you assess the upstream system. Decision making in a workflow starts with the downstream system, then works back to the upstream system.

Important

You should have already identified the downstream system or systems that you are going to send MediaLive output to, for this workflow. If you have not yet identified the downstream system, you must do some research before continuing with preparing your workflow. This guide can't help you to identify your downstream system. When you know what your downstream systems are, return to this section.

To identify the output group

  1. Obtain the following information from your downstream system.

    • The required output formats. For example, HLS.

    • The application protocol for each. For example, HTTP.

  2. Decide on the delivery mode for your outputs.

    • You might have an output that is on a server that is on your EC2 instance in your VPC. Or you might have an output that is in Amazon S3. If one or both of these situations apply, you might want to set up for delivery via your VPC. For more information, see Delivering outputs via your VPC.

    • If you don't have any of these types of outputs, you will deliver in the regular way.

  3. Make sure that MediaLive includes an output group that supports the output format and protocol that the downstream system requires. See Supported containers and downstream systems.

  4. If your preferred downstream system is another AWS media service, read this for information about choosing the service.

  5. If your downstream system supports Microsoft Smooth Streaming, see Options for handling Microsoft Smooth output for options.

  6. Decide if you want to create an archive output group in order to produce an archive file of the content. An archive file is a supplement to streaming; it isn't itself a streaming output. Typically, you create an archive file as a permanent file version of the streaming output.

  7. Decide if you want to create a frame capture output group in order to produce a frame capture output. A frame capture output is a supplement to streaming; it isn't itself a streaming output. This type of output might be useful for your workflow. For example, you might use a frame capture output to create thumbnails of the content.

  8. Make a note of the output groups that you decide on. You will need this information when you design the output groups.

    For example, after you have followed these steps, you might have this list of output groups:

    • One HLS output group with AWS Elemental MediaPackage as the downstream system.

    • One RTMP output group sending to the downstream system of a social media site.

    • One Archive output group as a record.
