callback OnBrowserCreated never called

[biomerge]

I'm having troubles integrating CEF into an existing project. I have a small demo project that renders google.com correctly, but the integration of the very same code into a big existing project doesn't even create a browser window.
Both project have access to the same DLLs, pak files, etc...

There are two main differences between the demo project and the existing project:
The number of processes spawned after CefInitialize and the fact that OnBrowserCreated is not called after CreateBrowser.
Some more details about these problems below.

1) Behavior after CefInitialize:

Demo project:
3 processes are spawned:
"--type=gpu-process"
"--type=utility --service-sandbox-type=network"
"--type=utility --service-sandbox-type=utility"

Existing project:
only 1 process is spawned:
"--type=gpu-process"

2) Behavior after CefBrowserHost::CreateBrowser

Demo project:
Callback OnBrowserCreated is called and two renderer processes are spawned.

Existing project:
Callback OnBrowserCreated is never called! No renderer process is spawned.

Debug.log:

A run in debug mode results in the following logging in both projects:

Code: Select all

[0106/113656.537:INFO:content_main_runner_impl.cc(960)] Chrome is running in full browser mode.
[0106/113656.762:WARNING:angle_platform_impl.cc(52)] initializeD3DDevice(721): Failed creating Debug D3D11 device - falling back to release runtime.

About CefInitialize

Both projects spawn the same executable "CefSubProcess".

Code: Select all

CefString(&settings.browser_subprocess_path).FromASCII("CefSubProcess.exe");
settings.multi_threaded_message_loop = false;
settings.no_sandbox = true;

Any idea what might trigger the different behavior between both programs sharing the same CEF code? I use Chromium 78.3.9.
Thank you!

Have you checked that CefBrowser::CreateBrowser is actually called?

Yes that gets called for sure. I think the problem is situated earlier on after CefInitialize and the fact that the utility subprocesses (CL: "--type=utility") are not spawned.

Thanks for the reply but I managed to fix it. CefDoMessageLoopWork calls got blocked in the big application. Sorry for the inconvenience!
