Create the SRT caller output group

After you have designed the contents of the output and you have coordinated delivery of the output with the downstream system, you can create the SRT caller output group.

  1. On the Create channel page, under Output groups, choose Add.

  2. In the Add output group section, choose SRT, and then choose Confirm. More sections appear.

    The form for this output group is broken down into the following sections:

    • SRT settings: Features that apply at the output group level, not in individual outputs.

    • SRT outputs: Outputs in the output group.

    • Output > Destinations: The URL and encryption fields for each output.

    • Output > Output settings: Networking and transport stream settings, and configure individual PIDs.

    • Output > Stream settings: Configuration of the video, audio, and captions in each output.

    For information about each section, see the topics listed after this procedure.

  3. After you have finished setting up this output group and its outputs, you can create another output group (of any type), if your plan requires it. Otherwise, go to Save the channel

SRT settings

In the SRT settings sections, complete the fields:

  • Name: Enter a name for the output group. This name is internal to MediaLive; it doesn't appear in the output. For example, Sports Game.

  • Input loss action: Choose a value. For details, choose the Info link. For detailed information about input loss handling for all output groups in the channel, see Handling loss of video input.

SRT outputs

The SRT outputs section shows the single output that is added by default. Choose Add output if you want to send the content to more destinations.

In each output, choose the Settings link to show three subsections:

Output > Destinations

In each output, you must specify one destination (for a single-pipeline channel) or two destinations (for a standard channel). You must also configure encryption for each destination.

  • Enter the destination URL or URLs, including the port number. You obtained this information when you discussed your requirements with the downstream system. For example:

    srt://203.0.113.22:5000

    srt://203.0.113.88:5001

  • Stream ID: Optional.

  • In each destination, select the secret that you obtained from the operator of Secrets Manager. You can select the secret by its ARN or its name.

Output > Output settings

Enter a user-friendly name for the output, or leave the default. This name is internal to MediaLive and doesn't appear in the output.

The remainder of this section contains fields that let you configure the following:

  • Network behavior.

  • Characteristics of the transport stream (in the Container section).

  • PID values (in the PID Settings section).

    These fields cover the SI/PSI and other data. For each of the SI/PSI PIDs, you can specify a custom value or you can let MediaLive use the default value.

    For other data, complete the fields as appropriate. With some of these fields, the behavior is different for fields that you leave empty. MediaLive might omit the data from the transport stream. Or MediaLive might use default values.

Change any values as appropriate. For details about a field, choose the Info link next to the field in the MediaLive console.

Output > Stream settings

The fields in this section relate to the encoding of the video, audio, and captions streams (encodes) in the output.

For information about creating encodes, see the following sections:
