Hi @SGaist

Thanks.

QWebEngineUrlRequestInterceptor is limited and only allows you to modify the HTTP request headers and/or perform an HTTP REDIRECT which I'd like to avoid here.

The old code doesn't perform any REDIRECT.

QByteArray since you want to concatenate two strings

Indeed. As stated in the title, this is an old code :-)

@maxt Imusing Qt 5.15.2 version..my project is to connect the ip camera using ip address and viewing the output of the video of the ip camera using webengineview. When I worked with project in debug build..the output is showing.But when I try to build it in release build,it is not working.the web page is loading..but the video output is not loading..But,in web browser,it is showing. I have included all the necessay libraries to load the webview and i have succesfully viewed the output of the ip camera in debug build.The error message is:

[66928:64908:0823/193205.676:INFO:CONSOLE(1)] "Uncaught NotSupportedError: Failed to execute 'addSourceBuffer' on 'MediaSource': The type provided ('video/mp4;codecs="avc1.640029"') is unsupported.", source: http://192.168.56.50/module/videoMediaSource.js (1)

It turned out the error I needed to research specifically was ERROR:zygote_host_impl_linux.cc(100). I found a solution here:

https://stackoverflow.com/questions/62284578/docker-errorzygote-host-impl-linux-cc89-running-as-root-without-no-sandb

And the new Dockerfile is

# Use the official Python base image FROM python:3.11-bullseye RUN pip install numpy && pip install setuptools # Copy the debPackages.txt file COPY debPackages.txt . # Install Qt6 dependencies RUN apt-get update && apt-get install $(grep -vE "^\s*#" debPackages.txt | tr "\n" " ") -y # Set the working directory in the container WORKDIR /app # Copy the requirements.txt file COPY requirements.txt . # Upgrade pip RUN pip install --upgrade pip # Install the Python dependencies RUN pip install --no-cache-dir -r requirements.txt # Copy the project files COPY . . ENV PYTHONDONTWRITEBYTECODE=true # Export QT specific settings ENV QT_DEBUG_PLUGINS=1 ENV QT_QPA_PLATFORM=offscreen ENV QTWEBENGINE_DISABLE_SANDBOX=1 RUN pip install . # Expose the port the application runs on EXPOSE 8000 CMD ["coverage", "run", "-m", "pytest"]

so adding ENV QTWEBENGINE_DISABLE_SANDBOX=1 fixed everything.

@jsulm

Understood.
I will be looking for it. Thank you very much for your guidance.

@Nivedkarun Use QWebEngineView

@dschoni Did you ever get a response?

I have exactly the same problem.

@Lahearle Can you reproduce the issue following my steps?

I think I found the issue - it was because I the app uses a tray icon and WM_CLOSE doesn't fully close the app. This appears to play badly with the Windows restart manager. The solution was to use a custom script to terminate the app during update / removal.

@Hunglx Hello. Thank you very much for your information. I've understood that I need to switch to Qt 6.5, and set several attributes to QWebEngineProfile. I'll make a try.

Thank you.

Any update on this issue?
