使用 Roku 广告框架 (RAF) 的 DFP VMAP 中贴片广告

Question

我是运行我从 Roku 网站获得的 RAF 示例代码中的插播广告 url。我在 google IMA 视频套件 isspector 中测试了 url，它有一个前贴片广告、一个中贴片广告和一个后贴片广告。该代码适用于没有任何中贴片广告（单个 VAST 标记）的前贴片广告 url。但是来自 VAMP url 的广告中的 none 正在使用以下代码播放。当我打印 'adPods.count()' 时，我得到的结果总是 0。适用于：单一、内联、线性广告 - http://pubads.g.doubleclick.net/gampad/ads?sz=640x480&iu=/124319096/external/single_ad_samples&ciu_szs=300x250&impl=s&gdfp_req=1&env=vp&output=vast&unviewed_position_start=1&cust_params=deployment%3Ddevsite%26sample_ct%3Dlinear&correlator=

不适用于 VMAP 前轮、中轮和 Post 轮，单个广告：http://pubads.g.doubleclick.net/gampad/ads?sz=640x480&iu=/124319096/external/ad_rule_samples&ciu_szs=300x250&ad_rule=1&impl=s&gdfp_req=1&env=vp&output=vmap&unviewed_position_start=1&cust_params=deployment%3Ddevsite%26sample_ar%3Dpremidpost&cmsid=496&vid=short_onecue&correlator=

代码如下：

Sub PlayContentWithAds(videoContent as Object)
    canvas = CreateObject("roImageCanvas")
    canvas.SetLayer(1, {color: "#000000"})
    canvas.SetLayer(2, {text: "Loading..."})
    canvas.Show()

    adIface = Roku_Ads()
    print "Roku_Ads library version: " + adIface.getLibVersion()
    ' Normally, would set publisher's ad URL here.  Otherwise uses default Roku ad server (with single preroll placeholder ad)
    adIface.setAdUrl("http://pubads.g.doubleclick.net/gampad/ads?sz=640x480&iu=/124319096/external/ad_rule_samples&ciu_szs=300x250&ad_rule=1&impl=s&gdfp_req=1&env=vp&output=vmap&unviewed_position_start=1&cust_params=deployment%3Ddevsite%26sample_ar%3Dpremidpost&cmsid=496&vid=short_onecue&correlator=")
    adPods = adIface.getAds()
    print "printing adpods count here.."
    print adPods.count()
    playContent = adIface.showAds(adPods) ' show preroll ad pod (if any)


    curPos = 0
    if playContent
        videoScreen = PlayVideoContent(videoContent)
    end if

    while playContent 
        videoMsg = wait(0, videoScreen.GetMessagePort())
        if type(videoMsg) = "roVideoScreenEvent" 
            if videoMsg.isStreamStarted()
                canvas.ClearLayer(2)
            end if
            if videoMsg.isPlaybackPosition()
                ' cache current playback position for resume after midroll ads
                curPos = videoMsg.GetIndex()
            end if
            'check for midroll/postroll ad pods
            adPods = adIface.getAds(videoMsg)
            if adPods <> invalid and adPods.Count() > 0
                ' stop video playback to prepare for midroll ad render
                videoScreen.Close()
                playContent = adIface.showAds(adPods)
                if playContent
                    ' resume video playback after midroll ads
                    videoContent.PlayStart = curPos
                    videoScreen = PlayVideoContent(videoContent)
                end if
                ' if !playContent, User exited ad view, returning to content selection
            end if ' adPods <> invalid

            if videoMsg.isFullResult() or videoMsg.isRequestFailed() or videoMsg.isPartialResult() or videoMsg.isScreenClosed()
                playContent = false
            end if
        end if ' roVideoScreenEvent
    end while
    if type(videoScreen) = "roVideoScreen" then videoScreen.Close()
End Sub

尝试更新您盒子上的固件。软件更新也将更新 RAF。旧版本的 RAF 可能无法正确解析此 XML。
