Working with MediaLive devices - AWS Elemental MediaLive

Working with MediaLive devices

A MediaLive device is the representation within MediaLive of an AWS Elemental Link hardware device that is connected to MediaLive. The AWS Elemental Link device can stream content to any MediaLive channel.

The AWS Elemental Link device is connected via the internet to MediaLive in a specific Region in your AWS account. You don't need to set up AWS Elemental Link devices within MediaLive. Instead, the AWS Elemental Link device automatically connects itself to your AWS account, and automatically becomes visible to MediaLive.

You set up to use the content from a specific AWS Elemental Link by creating an input that uses the MediaLive device that corresponds to that hardware device. You can then work with the input in MediaLive as you would work with any input. For more information, see Working with AWS Elemental Link devices.

To clarify the terminology:

  • AWS Elemental Link is a model of a physical hardware device.

  • MediaLive device is the representation of AWS Elemental Link within MediaLive.

Creating a MediaLive device

You don't create MediaLive devices. Instead, when an operator at the upstream system connects an AWS Elemental Link to the internet and powers on the hardware, the AWS Elemental Link connects to MediaLive. On the MediaLive console, the Devices entry appears in the navigation pane. The new MediaLive device appears in the Input devices section.

Editing or viewing details for a MediaLive device

You can change the maximum bitrate and the source for the MediaLive device. You can also view all the settings for the connection between MediaLive and the AWS Elemental Link.

To edit or view an input

  1. Open the MediaLive console at https://console.aws.amazon.com/medialive/.

  2. In the navigation pane, choose Devices.

  3. In Devices, go to the card for the MediaLive device that you want, and choose the link. If there are many MediaLive devices, enter part of the name to filter the list.

  4. The details page for this MediaLive device shows information about the device, including the following:

    • The unique ID of the AWS Elemental Link device (displayed at the top of the page)

      A thumbnail of the content that is currently being pushed by the device, if there is any being pushed. The device generate the thumbnails by capturing a video frame approximately every 5 seconds.

    • The status of the connection to the AWS Elemental Link device.

    • A device ARN that includes that unique ID.

  5. (Optional) On the Device page, choose Edit.

  6. Change any field as needed:

    • Input source – This field configures the AWS Elemental Link device for which content to send—SDI content or HDMI content. The AWS Elemental Link device can receive content at an SDI port and an HDMI port. Typically, in a production environment, the device receives content at only one port. Therefore, you can set this field to Auto. In some situations, the operator of the AWS Elemental Link device might instruct you to set this field to SDI or HDMI.

    • Maximum bitrate – Enter a bitrate in bits/sec only if you want to throttle the bitrate that AWS Elemental Link uses to deliver the stream. Leave this field blank to let AWS Elemental Link determine the bitrate that is best for the network conditions between the hardware device and MediaLive.

  7. Choose Update.

    Wait for the input State to return to In use or Idle before performing another action with this input.

The new values appear in Active input and Max bitrate in Device settings. MediaLive sends the new values for these settings to the AWS Elemental Link, so that AWS Elemental Link can update itself.

Viewing the status of a MediaLive device

To verify the status of the MediaLive device, view the details. On the details page, the Connection state and Device state below the thumbnail define the status.

  • Disconnected and Idle – The MediaLive device is not connected to the internet.

  • Connected and Idle – The MediaLive device is connected to the internet but it is not sending content.

  • Connected and Streaming– The MediaLive device is connected to the internet and is sending content.

Deleting a MediaLive device

You don't delete MediaLive devices. Instead, if the upstream system deregisters the AWS Elemental Link hardware device, the MediaLive device no longer appears in the Devices section. Note that this is the only way that the MediaLive device is removed.

  • If someone powers down the hardware device, the MediaLive device still appears in the list.

  • If the AWS Elemental Link is disconnected from the internet or the connection from MediaLive to the AWS Elemental Link device is down, the MediaLive device still appears in the list.
