Question

我正在运行来自Roku网站的RAF示例代码中的midroll广告网址。我测试了谷歌IMA视频套件ispector中的网址，它有一个预卷，一个midroll和一个postroll广告。该代码适用于没有任何midroll广告（单个VAST代码）的preroll网址。但是，VAMP网址中的广告都没有播放以下代码。当我打印＆＃39; adPods.count（）＆＃39;我总是得到0的结果。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=

对于VMAP预制，中期和后贴片广告不起作用：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=

以下是代码：

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

尝试更新包装盒上的固件。软件更新也将更新RAF。旧版本的RAF可能无法正确解析此XML。

使用Roku广告框架（RAF）
