Custom challenge data in a PlayReady license acquisition req

Use the encodingtype="PlayReadyLicenseAcquistionAndChallenge" content metadata parameter and the encodingKey parameter where '%%%' is the sentinel in the value separating the license acquisition url from the custom challenge data. Example:

videoclip.encodingtype = "PlayReadyLicenseAcquisitionAndChallenge"
videoclip.encodingKey = "https://www.licenseaquistionurl.asmx" + "%%%" + "YourCustomDataHere"

Kevin, could you please clarify me on this:

Where do I add the encodingtype and encodingKey properties?

like this:

player = CreateObject("roVideoPlayer")
player.SetContentList([{
        Stream: { 
            url: "http://play.ready/url.ism/Manifest"
        },
        StreamFormat: "ism"
        SwitchingStrategy: "full-adaptation",
        encodingtype: "PlayReadyLicenseAcquisitionAndChallenge",
        encodingKey: "https://www.licenseaquistionurl.asmx" + "%%%" + "YourCustomDataHere"
}])

or like this:

player = CreateObject("roVideoPlayer")
player.SetContentList([{
        Stream: { 
            url: "http://play.ready/url.ism/Manifest",
            encodingtype: "PlayReadyLicenseAcquisitionAndChallenge",
            encodingKey: "https://www.licenseaquistionurl.asmx" + "%%%" + "YourCustomDataHere"
        },
        StreamFormat: "ism"
        SwitchingStrategy: "full-adaptation"
}])

or is it some other way? I can't find it in the rokudev documentation..

Also, If I just want to use encodingKey= "https://www.licenseaquistionurl.asmx" without custom data, is it possible to implement? does the encodingtype property still maintain as "PlayReadyLicenseAcquisitionAndChallenge"?

Thank you for your attention.
Márcio.

Bumping this post because I'm also working on getting Playready streams to work on Roku. I would also like to know if the encodingtype and encodingkey are documented anywhere.

I not want overwrite the url of acquire license, but get it from manifest. Is possibile?
Or is possibile write %%% + cutomData without url?
