Using the REST API - AWS Elemental Live

Using the REST API

This description assumes that you are familiar with using the REST API and with the XML body for a live_event.

To configure the event using the REST API

  1. Enter a POST or PUT command in the usual way. Use POST to create a new event. Use PUT to modify an existing event:

    POST http://<Live IP Address>/live_events
    PUT http://<Live IP Address>/live_events/<live event id>

  2. In the body of the request, include one motion_image_inserter element inside the live_event tag. The XML is structured as follows.

    You can configure some or all the information in the non-running event, but you must at least set the following tags:

    • insertion_mode

    • enable_rest

    Make sure that you configure for the desired motion overlay behavior when the event first starts:

    • If you want the motion overlay to appear as soon as the event starts, specify all the tags. Make sure that you set active to true, and make sure that you leave action_time empty.

    • If you don't want the motion overlay to appear as soon as the event starts, set active to false.

    You can configure the remaining tags after you've started the event, when you want to run the first motion overlay.

    For detailed information about the tags, see Fields for a MOV asset.

    <motion_image_inserter>
    <action_time>
    <active>
    <enable_rest>
    <full_frame>
    <image_x>
    <image_y>
    <insertion_mode>
    <loop_input>
    <motion_image_inserter_input>
      <uri>
      <password>
      <username>
    </motion_image_inserter_input>
</motion_image_inserter>

  3. The response repeats back the data that you posted with <ID> tags for many elements including IDs for the following motion image inserter elements:

    • motion_image_inserter

    • motion_image_inserter_input

Example

The following request creates an event with the name myLiveEvent. The event includes a motion_image_inserter section that inserts the motion overlay at a specific time:
