Enabling thumbnails in a channel

You must enable the thumbnails feature in each channel.

You can enable or disable thumbnails only when the channel is idle (not running).

Providing IAM access

For the thumbnails feature to work, MediaLive needs access to Amazon S3:

• If your organization uses the MediaLiveAccessRole trusted entity, go to the Channel and input details page of the channel configuration, and look in the General info section. If the Update role button appears in this section, select the button. If the button doesn't appear, then the trusted entity already has the access that it needs

• If your organization uses custom trusted entity roles, then an IAM administrator must update the appropriate trusted entity roles. For information about the operations to add, read Reference: summary of requirements for the MediaLive trusted entity. Search for thumbnails on that page. For information about how to update the role, see Step 2: Create the trusted entity — complex option.

Enabling thumbnails on the console

Note

This section assumes that you are familiar with creating or editing a channel, as described in Creating a channel from scratch.

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

2. On the Create channel page or Edit channel page, choose General settings, then open the Thumbnail configuration section.

3. Select Enable thumbnail configuration. In State, choose AUTO or DISABLED.

Enabling thumbnails programmatically

To enable the thumbnails feature, include the ThumbnailConfiguration group of parameters in the JSON for the channel. Set the State parameter to AUTO (to enable) or DISABLED.

The following example shows the relative location of the parameters in the JSON for the channel.
