Prebid Video | Prebid Server Example with Ooyala

An example of a pre-roll ad using Prebid Server and Ooyala.

Important: This example uses a test version of Prebid.js hosted on our CDN that is not recommended for production use. It includes all available adapters. Production implementations should build from source or customize the build using the Download page to make sure only the necessary bidder adapters are included.

Warning: Do not forget to exchange the placementId in the code examples with your own placementId!

Place this code in the page header.

 You must load the core player script, the scripts for
 whatever video formats you want to support, and the scripts
 for the ad manager you want to use.

    /* PRE-DEFINE `invokeVideoPlayer`

    Because we have no way of knowing when all the bids will be
    returned from Prebid we can't be sure that the browser will
    reach the point where `invokeVideoPlayer` is defined before
    `bidsBackHandler` fires and tries to call it.

    To prevent an "`invokeVideoPlayer` not defined" error, we
    pre-define it before we make the call to Prebid, and redefine
    it later on with the code to create the player and play the

            'pcode': 'lsbWkyOjtI6LOjmlqk2o5I-TsWRA',
            'playerBrandingId': '45b8294c6ad14265b2b47586c911cb07',

            Create a new JSON object in the player parameters. The key
            should be the ad manager you're using (in our case we're
            using the Google IMA ads manager, so the key is
            `"google-ima-ads-manager"`). The IMA ads manager requires
            an ad set (which we've named `"all_ads"`).

            For more information see the Ooyala docs:


            Make sure the ad parameters are properly formatted JSON.
            "google-ima-ads-manager": {
                "all_ads": [{
                    "position": "0",
                    "position_type": "t",

        Use the `OO.ready()` event to make sure that all the
        necessary Ooyala plugins have loaded before attempting to
        create the player. Once it has, call `create()` and pass

        - the div you're creating the player in

        - the ID of the content video

        - the player settings we created above */

        OO.ready(function() {
            console.log("OO is ready, invoking");
            window.pp = OO.Player.create('container', 'ltcG54NzE6Bxk08Mqs1_KMcQZDN7lH8N', playerParam);


    If Prebid returned bids before the browser reached the end of
    the page, the first version of `invokeVideoPlayer` will have
    been called from `bidsBackHandler`, so the winning VAST tag will
    be stored in `tempTag`.

    If that's the case, we want to call the "real" version of
    `invokeVideoPlayer` with the stored URL to create the player and
    play the ad.

    If `tempTag` is not defined, that means the browser reached the
    end of the page before the bids came back from Prebid, meaning
    the "real" version of `invokeVideoPlayer` was already called.

    if (tempTag) {
        tempTag = false;
