Feature Request

Description

As a follow-up to a comment made in another issue (#10249 (comment)), I'm creating this feature request to add support for video assets in Prebid.js Native.

The video asset could be integrated for both the 'legacy' native approach and for the ORTB native approach that are still currently supported in Prebid.js; additionally the conversion functions that exist in the native.js could be updated to support forward and backward conversions for this video field.

As an example , the request and the response could look like the following:

legacy request (in adUnit):

native: {
  video: {
    required: true|false,
    maxduration: 60,
    minduration: 5,
    mimes: ['...']
    protocols: [1,2,3,...]
  }
}

legacy response:

bid.native.video = '...'  // URL to vast XML

ORTB request:

native: {
  ortb: {
    assets: [{
      id: 0,
      required: true|false,
      video: {
        maxduration: 60,
        minduration: 5,
        mimes: ['...']
        protocols: [1,2,3,...]
      }
    }]
  }
}

ORTB response:

native: {
  ortb: {
    assets: [{
      id: 0,
      video: {
        vasttag: '...'  // URL to vast XML
      }
    }]
  }
}

To note - I'm suggesting the support for legacy since it seems that some people might already be trying to use it, despite it not necessarily being documented on prebid.org, since someone added it to our adapter for example (#9396).

We'll raise this with the Publishers PMC to get feedback on how we should prioritize this.
