Using Spotify Web SDK in Qt6

cobook

I'm trying to add Spotify feature using QtWebEngine in MacOS. Qt 6.8.0

Code: in the qml file, WebEngineView turn on the index.html files.
index.html have javascript codes about the spotify.

My Qt used Chrome widevine, and when I run, it makes this error.

js: Uncaught (in promise) EMEError: No supported keysystem was found.

This error didn't come out when run index.html in chrome web browser directly.

I searched, and found this document, so I tried to rebuild qt using under command.

./configure -webengine-proprietary-codecs

But it cames out another error

WARNING: QtWebEngine won't be built. Python3 html5lib is missing.
WARNING: QtPdf won't be built. Python3 html5lib is missing.

Python3 is already installed in my labtop,
and I install html5lib in python virtual environments.
Is it wrong way??
Nothing changes.

Is Python in PATH when you're calling configure? And I guess configure does not you any of your virtual environments and will not find html5lib there.

Ok I found how to connect the python path.
I add the my python virtual environment path. but still nothing has changed.

$ pwd
/Users/Qt/6.8.0/Src

$ which python3
/Users/Qt/6.8.0/Src/venv/bin/python3

$ ./configure -webengine-proprietary-codecs

@Dilloncarr hi,

From what @cobook wrote, the main fix was to move to Ubuntu. Did you already tried that ?
Also, which version of Qt are you using ?
How did you install it ?

Dilloncarr

I tried switching to Ubuntu, it didn't work

SGaist

And you also installed that missing library ?

Dilloncarr

yeh right

SGaist

Please describe the exact setup you are using:

Qt version
How you got it
How you setup your build environment
How are trying to build the QtWebengine module
