QT4 QWebview显示视频一片黑

[单单单单点]

QT4 QWebview显示视频一片黑，小白求大神指点，网上没找到解决方案，代码如下

QWebSettings *settings = QWebSettings::globalSettings();
settings->setAttribute(QWebSettings::PluginsEnabled,true);
settings->setAttribute(QWebSettings::JavaEnabled,true);
settings->setAttribute(QWebSettings::JavascriptEnabled,true);
settings->setAttribute(QWebSettings::JavascriptCanOpenWindows,true);
settings->setAttribute(QWebSettings::JavascriptCanAccessClipboard,true);
settings->setAttribute(QWebSettings::DeveloperExtrasEnabled,true);
settings->setAttribute(QWebSettings::SpatialNavigationEnabled,true);
settings->setAttribute(QWebSettings::LinksIncludedInFocusChain,true);
settings->setAttribute(QWebSettings::AcceleratedCompositingEnabled,true);
settings->setAttribute(QWebSettings::AutoLoadImages,true);

// ui->webView->load(QUrl("http://v.qq.com/cover/1/1l62pv50l5qzt1e.html?vid=z0126s1lazw"));//webview加载地址
QFile h("D:/QTproject/Car/video.html");
h.open(QIODevice::ReadOnly);
if(h.error() == QFile::OpenError)
{
qDebug("ss","sss");
}
ui->webView->setHtml(QString::fromUtf8(h.readAll().constData()));

h.close();
ui->webView->show();

我的html文件在网页中是这样的


在程序中是这样的

QWebview是早期是webkit内核，从5.5之后换成了谷歌的浏览器内核，都不支持active插件，你必须用IE浏览器打开才行!

是啊，所以我今天刚改了，不用webview了，我改用label来显示图片，抓取静态图片 一帧一帧的播放，效果还蛮不错的

void MainWindow::PicConnect(QString PicUrl) { //connect to picture QNetworkAccessManager *manager; manager = new QNetworkAccessManager(this); connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(slot_replyFinished(QNetworkReply*))); QNetworkRequest request; request.setUrl(QUrl(PicUrl)); manager->get(request); delete & manager; } void MainWindow::slot_replyFinished(QNetworkReply* reply) { //save the picture QPixmap pix; QByteArray data = reply->readAll(); pix.loadFromData(data, "JPG"); pix.save("D:/QTproject/Car/tmp1.jpg", "JPG", 100); } void MainWindow::ShowPic() { isPicOnLabel=true; QString PU = "http://"+this->serverAddress+":8080/?action=snapshot"; while(1) { PicConnect(PU); if(isPicOnLabel==false) break; QEventLoop eventloop; QTimer::singleShot(60, &eventloop, SLOT(quit()));//60帧左右 eventloop.exec(); if(! ( img.load("D:/QTproject/Car/tmp1.jpg") ) ) //加载图像 { QMessageBox::information(this, "error", "open error"); return; } scaledimg=img.scaled(320,240,Qt::KeepAspectRatio); ui->PicLabel->setPixmap(QPixmap::fromImage(scaledimg)); } } void MainWindow::StopPic() { isPicOnLabel=false; } 这是我显示视频流的代码，运行起来一段时间没问题，但是一段时间过后，就会报错QThread::start: Failed to create thread (????????Ч??)，我也没进行线程操作啊...求大神解答一下

问题已经解决，QWebview无法解析mjpg-streamer的视频流，最后我用QLabel逐帧显示静态图片
