Prebid Video | Prebid Server Example with VideoJS

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

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!

    /* 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
    ad.

    In this first version, it simply stores the winning VAST to
    use later. */
