Disabling all Elemental Inference features in a channel

Follow this procedure to disable all Elemental Inference features in a MediaLive channel.

In this procedure, you disable a feature in the relevant MediaLive channel outputs. And you disable the output for that feature in the Elemental Inference feed.

Make changes in MediaLive

Use update-channel to make changes in the MediaLive channel.

  1. In the InferenceSettings section of the JSON, remove the feedARN line.

  2. Make changes to remove the special configuration that applies to each feature that is enabled.

    To disable

    Action

    Event clipping

    There are no changes to make because there is no special configuration for this feature.
    Smart crop

    You must reconfigure every output that is set up for smart crop.

    1. Identify all the video encodes (video descriptions) for the target outputs where smart crop is enabled. For example, one target output might be the video encode (video description) named high_resolution in an output named output_A in the output group named My_outputgroup.

    2. In the JSON for each video description that you identified, change these parameters:

      • Width and Height: Set to values that are suitable when there is no Elemental Inference features occurring.

      • ScalingBehavior: Set to a value other than SMART_CROP.

See Setting up Elemental Inference features for the first time for an example of the JSON as it appears before you make these changes.

Result of changes to the MediaLive channel

When you save the changes to the channel, MediaLive takes these actions, in this order:

  • MediaLive uses associate-feed in Elemental Inference to disable all the outputs in the feed. It does this because it detects that there is no feedArn parameter in the channel.

    After an output is disabled, you can still read the existing metadata in the output for the next 24 hours. After that time, the output remains disabled, but its metadata is deleted.

  • MediaLive uses disassociate-feed to disassociate the channel (the resource) from the feed. It does this because it detects that there are no enabled outputs in the feed.

  • When the resource is disassociated from the feed, Elemental Inference automatically sets the status of the feed to Archived.

When you start the channel, MediaLive and Elemental Inference behave differently:

  • There is no feedArn parameter in the channel, so MediaLive stops sending the source video to Elemental Inference. (It doesn't put media.)

  • All the outputs are disabled, so Elemental Inference stops generating metadata for each feature.

These changes affect the charges that you incur:

  • You don't incur charges for the feed because all the outputs are disabled.

Re-enabling Elemental Inference features

The feed has been set to Archived, so you can't re-enable any Elemental Inference features. Instead, you must set up the features again.
