Qt5 QWebView HTML5视频标签支持 [英] Qt5 QWebView HTML5 video tag support
问题描述
大家好，
我正在尝试使用HTML5视频支持在Qt的QWebView中播放.mp4文件（我不能使用任何插件或adobe flash）。
我有3个系统。新安装的Windows 7 x64，Mac OS X 10.7和Windows xp X64。
我为Windows和Mac获得了新的Qt 5.0并安装在所有系统上。我还在所有3个系统上安装了完整的VLC（用于编解码器）。然后我创建一个Qt程序如下。
Hi All,
I am trying to play .mp4 file in QWebView of Qt using HTML5 video support(I can not use any plugin or adobe flash).
I have 3 system. newly installed Windows 7 x64, Mac OS X 10.7 and Windows xp X64.
I get new Qt 5.0 for windows and Mac and installed on all systems. I have also installed full VLC (for codec) on all 3 system. Then i create a Qt program as below.
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QWebView view;
QWebSettings::globalSettings()->setAttribute(QWebSettings::PluginsEnabled, true);
view.settings()->setAttribute(QWebSettings::PluginsEnabled, true);
QUrl url("http://www.html5test.com"); // html5test.com is site to check which features of html5 your browser supports.
view.load(url);
view.show();
return a.exec();
}
我看到的是在Windows 7和Mac OS X上支持的视频和音频标签，以及两个操作系统都支持MP4视频格式。但它在Windows XP x64上显示0评级，用于支持视频标签。我为此谷歌，但无法得到任何帮助。 为什么它说Windows xp X64不支持视频和音频标签？
之后，我尝试使用
What i see is On windows 7 and Mac OS X gives that video and audio tag supported, and also MP4 video format supported on both os. But it shows 0 rating on windows xp x64 for video tag support. I google for this but could not get anything helpful. Why it says that video and audio tag not supported on Windows xp X64?
After that i try to load a website having different videos with
<video>标记如下。
tag as below.
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
QWebView view;
QWebSettings::globalSettings()->setAttribute(QWebSettings::PluginsEnabled, true);
view.settings()->setAttribute(QWebSettings::PluginsEnabled, true);
QUrl url("http://shapeshed.com/examples/HTML5-video-element/");// having video tags
view.load(url);
view.show();
return a.exec();
}
当我运行上面的代码时，在Mac上按需要运行。在Windows 7上显示视频控件（播放按钮，搜索栏），但无法播放视频。并且在Windows xp X64机器上没有可见的视频和视频控制。
如果支持视频标签和mp4（和H.264），那么Windows 7机器是什么？
我在所有系统上都有其他浏览器，其中所有上述功能都很好。
是否需要进行任何系统特定设置？还是我错过了任何重要的步骤？
谢谢大家。
When i run above code, On Mac it run as per required. On windows 7 It shows the video controls (Play button, seek bar ) but it could not play video. And on Windows xp X64 machine no video and video control visible.
Whats Wrong with windows 7 machine if it says that video tag and mp4( and H.264) is supported?
I have other browsers too on all system where all above works nicely.
Is there any system specific settings required? or did I miss any important step(s)?
Thanks all.
推荐答案
我觉得QApplication非常依赖于QT框架但不是你的浏览器。
我现在通过python语言使用QApplication打开页面，它适用于png，html，文本和任何其他格式，但在我尝试加载ogg声音时，QApplication和QWebView似乎没有工作。
然后，在我的电脑上，当然是同一个操作系统，我用chrome打开那个页面，它确实有声音，声音加载了js事件。
我也真的受此问题的困扰。我希望我能很快找到解决方案
I seems that QApplication very depends on QT framework but not your browser.
I am now open page by using QApplication by python language, it work for png,html,text and anyother format, but where I try to load ogg sound, the QApplication and QWebView seems not work.
Also then, on my computer, the same os of course, I used chrome to open that page, it did has sound,and sound loaded js event emitted.
I really suffer on this problem too. I wish I could figure out the solution very soon
