Manage a VOD session

Using the Video Stitcher API, you create a video-on-demand (VOD) session each time you dynamically insert ads prior to delivery to client devices. When you create a session, the response includes the playback URL and information about the ads that you inserted into the video.

This page describes how to create and manage a VOD session that is not enabled by Google Ad Manager. For more information on these types of VOD sessions, see Manage a VOD session enabled by Google Ad Manager.

Before you begin

Create a session

To create a session for an ad-stitched video, use the projects.locations.vodSessions.create method.

When you create a VOD session, the following field is required:

  • adTracking: determines if the client player is expected to trigger playback and activity events or if the Video Stitcher API is expected to trigger playback events on behalf of the client player; for more information on client-side ad tracking, see Handle VOD client ad tracking.

    The example in this section uses server-side ad tracking.

When you create a VOD session, the following fields are optional:

REST

Before using any of the request data, make the following replacements:

  • PROJECT_NUMBER: your Google Cloud project number located in the Project number field on the IAM Settings page
  • LOCATION: the location in which to create your session; use one of the supported regions
    Show locations
    • us-central1
    • us-east1
    • us-west1
    • asia-east1
    • asia-south1
    • asia-southeast1
    • europe-west1
    • southamerica-east1
  • VOD_CONFIG_ID: the user-defined identifier for the VOD config

To send your request, expand one of these options:

You should receive a JSON response similar to the following:

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/vodSessions/SESSION_ID",
  "interstitials": {
    "sessionContent": {
      "duration": "60s"
    }
  },
  "playUri": "PLAY_URI", # This is the ad-stitched VOD URI

The Video Stitcher API generates a unique session ID for each request. A session expires after 4 hours.

An ad must be encoded before it can be stitched into a VOD session. When you create a session for an ad-stitched video, the Video Stitcher API determines if the ad has already been encoded from a previous session. If it has, the JSON response will indicate ad break events. The API only looks for encoded ads created by sessions associated with your Google Cloud project. For more information on this process, see the Overview.

Look at the JSON response. This response indicates that an ad was not stitched into the session. If this is the case, wait 5 minutes (for ad encoding) and then re-run the create session command. The response should now be similar to the following:

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/vodSessions/SESSION_ID",
  "interstitials": {
    "adBreaks": [
      {
        "progressEvents": [
          {
            "timeOffset": "0s",
            "events": [
              {
                "type": "IMPRESSION",
                "uri": "https://securepubads.g.doubleclick.net/pcs/view..."
              },
              {
                "type": "START",
                "uri": "https://pubads.g.doubleclick.net/pagead/interaction/..."
              },

                "uri": "https://pubads.g.doubleclick.net/pcs/click...",
                "id": "GDFP"
              },

  "assetId": "ASSET_ID",
  "adTracking": "SERVER",
  "vodConfig": "projects/PROJECT_NUMBER/locations/LOCATION/vodConfigs/VOD_CONFIG_ID"
}

The response is a VOD session object that contains the following fields:

If you're generating a session on behalf of your customers' devices, set the following parameters using HTTP headers:

Parameter HTTP Header
CLIENT_IP x-user-ip
REFERRER_URL referer
USER_AGENT user-agent

You can add the following headers to the preceding curl request:

-H "x-user-ip: CLIENT_IP" \
-H "referer: REFERRER_URL" \
-H "user-agent: USER_AGENT" \

Ad tag macros

An ad tag can contain macros, which can result in a different ad tag for each session. Macros are denoted by square brackets in the ad tag, as illustrated by the following example:

AD_TAG_URI&macro=[my-key]

The adTagUri is defined in the VOD config.

To substitute the value in the ad tag macro, provide a mapping in the adTagMacroMap field. For example, if you want to replace the [my-key] macro with the string my-value, you need to provide the following:

{
  ...
  "adTagMacroMap": {
    "my-key": "my-value"
  },
  ...
}

When the Video Stitcher API requests the ad metadata, it uses the following ad tag:

AD_TAG_URI&macro=my-value

Get a session

To get the session for an ad-stitched video, use the projects.locations.vodSessions.get method.

Handle client-side ad tracking

When client ad tracking is enabled, the player is responsible for triggering ad tracking events. You can find client-side tracking information in the interstitials object returned when the VOD session is created.

The interstitials object includes ad tracking information and metadata for companion ads parsed from ad tag requests. To inspect which ads are stitched, see Inspect VOD sessions.

Interstitials

Ad tracking information is grouped by ad breaks in the interstitials object.

Ad breaks may have progress events which specify the event URI and the time offset relative to the break start time for each event that has been fired. For more details about progress events, see the ProgressEvent reference documentation.

Ad breaks may also have activity events and companion ads. For more details about companion ads, see the CompanionAds reference documentation.

The following is an interstitials example:

{
  "adBreaks": [
    {
      "progressEvents": [
        {
          "timeOffset": "0s",
          "events": [
            {
              "type": "IMPRESSION",
              "uri": "https://example.com/impression"
            },
            {
              "type": "START",
              "uri": "https://example.com/start"
            }
          ]
        },
        {
          "timeOffset": "1.250s",
          "events": [
            {
              "type": "FIRST_QUARTILE",
              "uri": "https://example.com/firstquartile"
            }
          ]
        }
      ],
      "ads": [
        {
          "duration": "5s",
          "activityEvents": [
            {
              "type": "PAUSE",
              "uri": "https://example.com/pause"
            }
          ],
          "companionAds": {
            "required": "all",
            "companions": [
              {
                "width": 200,
                "height": 100,
                "staticResource": {
                  "uri": "https://example.com/static.png",
                  "creativeType": "image/png"
                }
              }
            ]
          }
        },
        {
          "duration": "10s"
        }
      ],
      "startTimeOffset": "0s",
      "endTimeOffset": "15.000s"
    }
  ],
  "sessionContent": {
      "duration": "120.000s"
  }
}

In the preceding example, there is one pre-roll ad break with two ads stitched into a VOD asset. The duration of the first ad is 5 seconds and the duration of the second ad is 10 seconds. The total stitched video length is 120 seconds, as identified by the duration field in sessionContent .

When the client receives this object, it should do the following:

  • Make a request to https://example.com/start at the start of the ad break.
  • Make a request to https://example.com/impression at the start of the ad break.
  • Make a request to https://example.com/pause whenever the viewer pauses the video during the first ad.
  • Make a request to https://example.com/firstQuartile 1.25 seconds into the first ad.
  • Load the companion ad https://example.com/static.png during the first ad.

Inspect VOD sessions

This section describes how to inspect the ad tag details and stitch details for a given VOD session. For more details, see the REST documentation for VodAdTagDetail and VodStitchDetail.

The adTagUri field, defined in the VOD config for the VOD session, specifies the URL from where ad metadata is retrieved. The Video Stitcher API also includes user metadata when it makes the request.

The /vodAdTagDetails endpoint contains the following information:

  • resolved ad tag
  • user metadata
  • request body and headers
  • response body and headers

The /vodStitchDetails endpoint contains the following information:

  • ad break ID
  • ad ID
  • ad time offset (in seconds)
  • reason if the ad was not inserted
  • ad media metadata

List ad tag details

To list the ad tag details for a VOD session, use the projects.locations.vodSessions.vodAdTagDetails.list method.

REST

Before using any of the request data, make the following replacements:

  • PROJECT_NUMBER: your Google Cloud project number located in the Project number field on the IAM Settings page
  • LOCATION: the location of your session; use one of the supported regions
    Show locations
    • us-central1
    • us-east1
    • us-west1
    • asia-east1
    • asia-south1
    • asia-southeast1
    • europe-west1
    • southamerica-east1
  • SESSION_ID: the session ID for the VOD session

To send your request, expand one of these options:

You should receive a JSON response similar to the following:

{
  "vodAdTagDetails" : [
    {
      "name": "projects/PROJECT_NUMBER/locations/LOCATION/vodSessions/SESSION_ID/vodAdTagDetails/VOD_AD_TAG_DETAILS_ID",
      "adRequests": [
        {
          "uri": "REQUEST_URL",
          "requestMetadata": "AD_TAG_REQUEST_METADATA",
          "responseMetadata": "AD_TAG_RESPONSE_METADATA"
