javascript - 在网页浏览器控件内播放视频(使用 javascript 添加)原因 "error #2148 try loosening flash security setting"

Question

I have to add videos using javascript

我正在创建 WPF 应用程序并读取 html 文件，我向文件添加了一些 javascript 函数以便能够添加多媒体文件，添加图像和音频效果很好，但不适用于视频，这是添加视频的函数:

function uiWebview_AddVideo()
{
    //var xpathh=uiWebview_storeSelection();
    var xpathh="/HTML[1]/BODY[1]/DIV[1]/P[1]/text()[1]|12|/HTML[1]/BODY[1]/DIV[1]/P[1]/text()[1]|22";
    var videopath="C:\\Users\\Administrateur\\Desktop\\movie.mp4";
    var index =1;
    var annotguid="annotguid";
    var annversion="annversion";
    var auteursurname="auteursurname";
    var foruserid=3;
    var selectionDetails = xpathh;
    selectionDetails = selectionDetails.split(/\|/g);
    var range = document.createRange();
    var selectionDetails0 = selectionDetails[0];
    selectionDetails0 = selectionDetails0.replace(/\//g,"/h:");
    selectionDetails0 = selectionDetails0.replace("h:t","t");
    var selectionDetails2 = selectionDetails[2];
    selectionDetails2 = selectionDetails2.replace(/\//g,"/h:");
    selectionDetails2 = selectionDetails2.replace("h:t","t");
    range.setStart(document.evaluate(selectionDetails0, document, nsResolver, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue, Number(selectionDetails[1]));
    range.setEnd(document.evaluate(selectionDetails2, document, nsResolver, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue, Number(selectionDetails[3]));


    //we create a SPAN element for every parts of matched keywords
    var span = document.createElement("span");
    var etoile = "*";
    var text1 = document.createTextNode(auteursurname);
    span.appendChild(text1);

    //we create a p element for every parts of matched keywords
    var p = document.createElement("aside");
    p.setAttribute("class","video");

    p.setAttribute("id",annotguid);
    p.setAttribute("style","display:block;");

    //*********** Video Tag ***********
    var video = document.createElement("video");
    video.innerHTML ="<video class=\"video-js\" width=\"640\" height=\"264\" controls preload poster=\"http://video-js.zencoder.com/oceans-clip.png\"><source src=\"C:\\Users\\Administrateur\\Desktop\\movie.mp4\" type='video/mp4; codecs=\"avc1.42E01E, mp4a.40.2\"' /><source src=\"C:\\Users\\Administrateur\\Desktop\\movie.webm\" type='video/webm; codecs=\"vp8, vorbis\"' /><source src=\"C:\\Users\\Administrateur\\Desktop\\movie.ogv\" type='video/ogg; codecs=\"theora, vorbis\"' /><object class=\"vjs-flash-fallback\" width=\"640\" height=\"264\" type=\"application/x-shockwave-flash\"data=\"http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf\"><param name=\"movie\" value=\"http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf\" /><param name=\"allowfullscreen\" value=\"true\" /><param name=\"flashvars\" value='config={\"playlist\":[\"http://video-js.zencoder.com/oceans-clip.png\", {\"url\": \"C:\\Users\\Administrateur\\Desktop\\movie.mp4\",\"autoPlay\":false,\"autoBuffering\":true}]}' /></object></video>";


    //video.appendChild(object);

    //***********************


    p.appendChild(span);
    var br = document.createElement("br");
    p.appendChild(br);
    p.appendChild(video);
    var d = document.createElement("d");
    d.appendChild(p);

    //p.setAttribute("class","bubble speech");

    var obj = range.startContainer; 
    while (obj.nodeName.toLowerCase() != 'p' && obj.nodeName.toLowerCase() != 'table'
    && obj.nodeName.toLowerCase() != 'p' && obj.nodeName.toLowerCase() != 'address' 
    && obj.nodeName.toLowerCase() != 'body' && obj.nodeName.toLowerCase() != 'body') {

        obj = obj.parentNode;
    }
    if (obj.nodeName.toLowerCase() == 'p' || obj.nodeName.toLowerCase() == 'table'
    || obj.nodeName.toLowerCase() == 'p' || obj.nodeName.toLowerCase() == 'address'
    || obj.nodeName.toLowerCase() == 'p' || obj.nodeName.toLowerCase() == 'p') {

        obj.parentNode.insertBefore(d, obj);
    }
    else {
        obj = range.commonAncestorContainer;
        obj.parentNode.insertBefore(d, obj);
    }

    //we create a A element for every parts of matched keywords
    var a = document.createElement("a");
    var etoile = "*";
    var text2 = document.createTextNode(etoile.concat(index).concat(" "));
    a.appendChild(text2);

    var chaine1="javascript:changestyledisplayblock('";
    var chaine2="')";
    var hre=(chaine1.concat(annotguid)).concat(chaine2);
    a.setAttribute("class", "marker");
    a.setAttribute("href", hre);
    a.setAttribute("style", "color:#004080;text-decoration:underline");

    range.insertNode(a);

    return;
}

我发现了许多其他 Flash 播放器，但似乎它们在我的网络浏览器(IE7)中不起作用 我正在寻找能够保证添加视频的播放器的指示 或者解决显示 Flash“201 无法加载流或剪辑文件尝试放松 Flash 安全设置错误 #2148”的错误的替代方法 谢谢

您可以通过拖放来使用媒体播放器控件(Winforms解决方案) http://msdn.microsoft.com/en-us/library/bb383953(v=vs.90).aspx

或者添加一个新的标签嵌入，其中包含也使用媒体播放器的视频/音频

    var embed = document.createElement("embed");
    embed.setAttribute("type", "application/x-mplayer2");
    embed.setAttribute("pluginspage", "http://www.microsoft.com/Windows/MediaPlayer");
    embed.setAttribute("src", videoSource);

这个解决方案对我有用;)
