And we really need it. My target is Qt 5. My approach was to download from github the qtwebengine module, supply everything it needs for compilation.

I saw the log saying "Proprietary codecs H, MP Enabled", so I assumed the configuration was ok. The compilation was successful. Then, my first idea was to copy the new dlls directly over the SDK ones in my application folder. That didn't work. My second idea was to recompile my application with everything generated by the qtwebengine build. The compilation was successful, but I still don't have MP3 support. I would be interested to know if you fixed the issue. I am also trying to recompile for Netflix support.

Any update on this? Or a guide on how to build QWebEngine with propretary codecs? I find hard to get the information for that. I fixed the issue and I posted the solution on stack. I'm sorry I forgot I posted my bug in here too. I have on return: Proprietary codecs H, MP Enabled Geolocation I just recompiled QtWebEngine on latest 5.

I added the widevinecdm. Qt WebEngine: Embedded build Also added this to my. I wish there was one clear guide on how to do all this.Proprietary codecs can be enabled by passing the following option to qmake when building Qt WebEngine:.

Warning: When distributing proprietary codec libraries, you must acquire licenses for them. FFmpeg is a cross-platform solution to record, convert, and stream audio and video.

It can be configured for use with several codecs, which rises licensing issues during distribution with the codec libraries. For some codecs, open source implementations, such as OpenHare available. The Chromium DevTools provide the ability to inspect and debug layout and performance issues of any web content. Dragging files into the browser is not actually part of HTML5, but it is supported.

Qt WebEngine supports viewing web content in fullscreen mode. For more information, see WebEngineSettings. This feature can be tested by playing a video from YouTube in Demo Browser or Nano Browserand clicking the full screen icon to go into fullscreen mode.

The video format most commonly used by DRM services, H. For more information about enabling the codecs, see Audio and Video Codecs. Note that on Windows an external GPS receiver must be connected to the application. For more information, see Qt Positioning. Qt WebEngine provides standard dialogs for these functions.

The latter are used only on eglfs platforms.

Since Qt 5. Except for the Adobe Flash Player plugin, the plugins must be loaded manually using the Chromium command line syntax with the --register-pepper-plugins argument. The argument value is a list of entries, separated by commas, that contain the file path and one or several MIME types, separated by semicolons:.

The Pepper Flash player plugin can be loaded automatically if it is installed in one of the following locations, depending on the platform:. You can also load the Pepper Flash player from a specific location by using command line arguments:.

By default, the Flash version is set to Qt WebEngine supports integrating spellchecking support into HTML forms to enable users to submit spellchecked messages. When the user clicks on an underlined misspelled word, the default context menu displays up to four suggestions.

Selecting one will replace the misspelled word. To be able to check the spelling, the spellchecker needs dictionaries. It supports dictionaries from the Hunspell projectbut they have to be compiled into a special binary format. A Hunspell dictionary consists of two files:. When the Qt WebEngine spellchecker initializes, it will try to load the bdict dictionaries and to check them for consistency.

This feature can be tested by building and running the Spellchecker Example. This feature can be used from custom menus or assigned to custom events. This feature can be tested by opening a web page in Simple Browser or Nano Browserand then selecting Page Source in the context menu. The Page Source context menu entry opens the source view in a new tab.

For example, the following incomplete URL also loads the source view of the qt.

Sign in to your account. Right now, with some restructuring of earlyinit and when the backend is set, all we could do is to force QtWebKit when Nouveau is used. Or wait for the new config system and set it in the config. I doubt it - e. There's a basic error displayed now, which is already much better than crashing. I'd like to add "Switch to QtWebKit backend" and "Use software rendering" buttons with the new config though.

I now pushed a nicer fix for this to the webengine-by-default branch, it'd be nice if some people could try it out, as I don't have Nouveau hardware. You should get a dialog asking you what to do, and the "force software rendering" button should correctly restart qutebrowser with software rendering turned on.

I'm just passing by, but this is a very wrong assumption — modern nouveau does not rely on bumblebee and needs to be always loaded for things like power management to work. So, indeed, checking modules is wrong here. Thanks for clarifying. I don't really know much about how bumblebee works, I just read through some of the source code when I made that assertion.

I am building Qt 5. I don't want to replace system GCC with my one. However, I don't see how can I alter the compiler absolute path that the Qt build system uses, as well as how to add custom flags. Does Qt 5. As BartoszKP adviced, it is required to make custom build platform. Easier but less elegant and less "educational" idea is to modify existing platform. This platform qmake. I added following lines at the very bottom of this file:. Now Qt build platform uses my custom compiler instead of existing system one, and it adds my custom linker flags.

With the clue I had from this response, and with the help of demobrowser example which is bundled with Qt I don't know what self is. I don't see anything about threads in your code.

You show a ScanPage method, but not where it gets called. As I said I don't know what it is init'ing, but that's probably not the place to create the application. Concentrate on the error messages. You should not be calling QApplication more than once. Whatever you mean about "but the trigger for the render method is an event recieved from socketIO module" needs sorting out to obey this e.

I had success with using the toolset instead. In addition I had to used the version from git instead of the offline installer because I was encountering missing precompiled header error while compiling webengine using the offline installer version. With the git version, it does not skip over webengine while compiling and can compile Qt with webengine in one go. Suggest the OP try relative to executable directory, but be prepared to try elsewhere if that turns out not to load the file.

This problem is caused by old version of EGL.

It has been resolved with Mesa-based EGL 1. Hi JonB, thanks for answer. Don't know why the editor here made a link out of simple browser py, shouldn't be one. How do you want to "add" it? If you specify path to your Cutelyst installation in build settings, you'll even be able to build the project from within Qt Creator.

Yes i will do, thank you! Of course, it is possible that meaningful messages are also being discarded! So, control of the Java Console output is still needed. It can be null and if it was null it would crash. Can you run this in a debugger and give a backtrace of the crash? Would explain the difference FPS rate QtWebEngine is not available for MinGW because the chromium project which it's build on doesn't support that compiler.

The minimal requirement is Visual Studio like explained in the platform notes of the module. There is not a built-in Qt offering. Otherwise, you'll have to see whether your particular use case can be addressed to your limited satisfaction via Regular Expression parsing from Qt.

But do you think it's something about compiler or system issue? I'm just trying to solve it. OK, I finally found the solution. Solution : Rebuild the qt with libnss.

I've heard some talk about the investigating what more they can do with how they render stuff, but I'm not sure what the state there is - I also didn't find an issue in their tracker so far.

Any recent information on this? Is it still not recommended to use those flags, and what might be reasons for auto disabling them? Agreed, but I had to switch to viewing some videos in my browser because of some DRM stuff that was recently enforced. Where i make a list situation?

Presumably like this.
