An example of an instream pre-roll ad using Prebid.js and Ooyala player .
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!

<!-- LOAD OOYALA PLUGINS
Load the Ooyala player scripts you plan to use.
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.
The scripts themselves and a guide for choosing which ones
you need can be found here:

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

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.
