How realistic / doable is it, to have this run on android?

This is really awesome. The best CEF attempt so far :)
Is there a way to grab the audio stream from CEF and pipe it through a Godot audio bus, so that we can make it 3d positional?

Try to understand why the project a friend of mine made https://www.exaequos.com/ is run slowly with my Godot CEF and keyboard is broken (while the secondary process works well)

Hey, great project!

I tried compiling this for windows and linux. Linux worked great, and I was able to run the sample projects by following the documentation.

For windows, compilation seems to finish successfully, but when running the sample project, it exits immediately as soon as I press "run", with no errors printed to the console. I've tried using different versions of godot, and compiling from previous releases, but I'm getting the same result.

Any ideas what I am missing?

Requested by @punto- https://godotengine.org/article/godot-web-progress-report-9/

For whatever reason the much more common "wget" module for python is returning 404s when attempting to download the cef binaries even though the URLs are definitely correct.

It may be worth noting in the README, as per this Stack Overflow Question, using "python3-wget" resolves the issue without having to change anything in the build.py

@raphipod I reverted CEF version to 103 it seems that on my Debian I have a failure. I have to investigate.

I modified MODULE_TARGET = "release" and GODOT_CPP_TARGET = "release" to MODULE_TARGET = "template_release" and GODOT_CPP_TARGET = "template_release" (It won't even work if I don't) ,After that it outputs many errors

1. I am confident that all dependencies are met, I have python 3.11, vs, cmake, git and ninja
2. I ran py -m pip install -r requirements.txt
3. I opened x64 native tools, and cd'd into the gdcef directory
4. I then ran py build.py from the x64 native tools terminal
5. ERROR

any ideas, I got this to compile on ubuntu wsl, but that only generates linux files ?

@daniel-sanche you can add your JS injection in https://github.com/Lecrapouille/gdcef/tree/master/addons/gdcef/demos/2D

I just discovered that running gdcef on windows 11 from the editor and subsequently stopping the debug run often results in the browser background process to not close at all.

This behaviour seems to be unconsistent from what I do with the open browser inside the godot run window.

I had an instance of this problem where after even some failed runs on godot, due to code errors, there were 5 ghost browser processes using almost all of my cpu.
I had to kill them one by one on the task manager.

Shouldn't be there, inside the browser process, a ping system which checks if the godot process that created it is still alive to prevent edge cases?

I was trying things out on the 2D demo project.

Upon downloading the newest Cef build, extracting it, the build.py script wants to compile "Godot CEF module", but it fails:

Scons is installed, I installed it with the requirements.txt via pip.

File structure is my personal fork of gdcef.

My wild guess is it that I need the special environment variables from Stigmee, am I wrong?

I really want to get this to compile completely because a web browser in Godot is just awesome!

I've successfully run the build.py and copied the build folder into the project directory. However, when I open the project in Godot 3.5 and click Play (F5) I get the error:

Invalid call. Nonexistent function 'initialize' in base 'Node'.

In the "2D" demo project, line 177 in CEF.gd is referred to. I've also tried running the "HelloCEF" project and received the same error. Am I missing something?

Hi.

I followed meticulously many times the installation process found here and here, but not once I was able to build the Godot extension.

I can't copy and past the entire stack trace since it's really too long, so this is the last part of stack trace I get:

I would like to point out that the third line of the installation process ./build.py doesn't work on my machine and I had to fix it to python3 ./build.py.

If you need to know more details, just ask.
Thank you in advance.

Currently:

• the CEF does not work for MacOs. Some parts need C# code and some knowledge is needed for exporting the project with Godot.
• Some Godot code needs to optimized (too many copies of textures and only a part shall be refreshed):

  gdcef/addons/gdcef/gdcef/src/gdbrowser.cpp

  Line 134 in ad2bb3d

• Add a add blocker. Prototype started here https://github.com/stigmee/gdnative-cef/tree/dev-extensions

OS: windows 11
Godot version: 4.2.1

Description: gdcef extension works fine on godot editor, but when I try to export for windows, an execute the build, I get this error stack

this is how looks in editor, vs windows build

this is how looks the windows build folder: (I added "cef_artifacts" folder manually)

First off thanks for the amazing project,
I have a similar issue to this but it has a unique cause.
The web view works when run within its own scene but when put as a child of another scene it crashes with no errors present.
This is the image of the web view scene:

and this is the structure of the other scene:

No matter the scene I place it in, as long as it is a child of another node, it will crash. I also tried copying a known working project and it still crashes but the demos work.
Here is what my log file is reporting:

If the issue is from my end, any help would be highly appreciated.

Is it possible if you compile this add-on with Godot as a module, so that I can use it without installing external programs?

When GDCef encounters a link that tries to open a new tab, it opens these links in new window on your OS, not in the game environment

Example: Try to click on the "Visit W3Schools.com!" link on this page

I tried to look into this, and it seems like it should be possible to override this by implementing the OnBeforePopup function. So far it hasn't worked for me, but I'll try to take another look at it later (unless someone else finds the fix first)

Hi, I'm using Godot 3.5.2. I'm now trying to run the demos to test around how it works for this WebView. Currently having build error. May I know what's the problem? I do follow the installation guideline, but not sure why getting this error...

Appreciate if anyone can assist XD

Right now, the CEF resources directory is hard-coded to be at /build in the godot project root. This probably doesn't make sense for most projects. And it is especially problematic for multi-platform projects, since each OS needs to read a different set of resources, which can't all be stored in the same folder.

One solution would be to allow the user to pass in a directory as part of the library initialization process

Missing in the paragraph:

Workaround: For Linux, for the moment, Stigmee does not find correctly the libcef.so while indicated in the gdnlib file. So for the moment:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$WORKSPACE_STIGMEE/stigmee/build

In API section missing telling that create_browser create browsers as Godot child node in the Scenegraph.

@raphipod

shotcut:

I just follow Readme.md. All the requires are installed.
Operation system: Deepin linux

Is there a way I can send data from the browser side (javascript) to my gdscript and vice-versa?
For example: If a html textbox is typed into can i get the data typed in gdscript?

• When selecting a paragraph with the mouse, then doing browser->GetMainFrame()->Copy() then pasting inside a text editor (or echo | cat -e) it gives the text with 3 consecutive '\n' instead of 1.

• When doing the same thing (browser->GetMainFrame()->Paste()) inside a GitHub input text, it works (\n are removed). But if I paste it for either in a Godot input text or getting the Godot clipboard, then my CEF application is freezing.

• In Godot when pressing keys they can repeat actions, I noticed this called many times browser->GetMainFrame()->Copy() with consequence it cumulates the selected text.

I think there is possible memory corruption with browser->GetMainFrame()->Copy()

The recent GitHub actions CI are a great start. But it would be helpful if we attempt to run the demo apps using the compiled library, to make sure everything loads correctly. This will help catch regressions going forward

Something like Gut could be helpful for this

Hey hey,

I haven't actually used your plugin, but I used your source as reference for integrating CEF into my project - thanks !
I have loaded mapbox in the embedded browser, and I noticed I couldn't drag the map, and it was zooming at 0,0 with the wheel : the issue was that CefMouseEvent::modifiers must be filled for each mouse event (click, move, wheel). So I'm pretty sure you have the same issue with this plugin. You need to save the modifiers in GDBrowserView and pass them in each m_browser->GetHost()->SendMouse*() in browser_io.cpp.

Cheers

Hello! I have managed to get this extension built and running with godot 3.5, but was wondering if there is some way to get widevine CDM support?
I am currently testing on windows 10.
I have tried to follow the instructions here to get the latest dll and place it in the appropriate folder and nothing happened.
I have also found this however I don't think I can pass in "enable-widevine-cdm" as a config argument for this?

Any help or insight would be appreciated 😄

It would be helpful to provide compiled versions of the library in the repo, either on each build, or on tagged releases.

Possible issues:

• are there licensing issues to worry about by providing the binaries?
• are there any costs for hosting the files?

Thank you very much for taking this over. It looks terrific, and I'm excited to use it.

Have you communicated with the original authors about relicensing the code? Unfortunately it isn't possible to go from GPL -> MIT without the consent of the copyright holder. Would you like me to reach out to see if they're open to the change?

@raphipod This project is now on the Godot asset lib https://godotengine.org/asset-library/asset/1426 I tagged it as 2D tools but I just realized that I should have placed all contents inside a addons/gdcef folder. Since i'm noob in Godot, raphipod can you confirm ?

Wonder what is missing?
