QtMultimedia is not currently supported on this platform or compiler. PyInstaller

I'm using PyInstaller v5.6.2. I prescribe pyinstaller mp3pyqt6.py, after which I add the necessary files to mp3pyqt6.spec, updating the pyinstaller mp3pyqt6.spec command. The console that comes with the application says: could not load multimedia backend "" QtMultimedia is not currently supported on this platform or compiler Is there a way to solve this? Any alternatives to PyInstaller?

I already compiled a project using QtMultimedia on pyqt5, everything went well there. But in this player PyInstaller doesn't work.

Solution

  • I got it to work, and these are the steps I took to get it to run and compile.

    1. Create a new directory and paste your script inside of it as main.py.
    2. py -m venv venv && venv\scripts\activate
    3. py -m pip install --upgrade pip pyinstaller PyQt6
    4. pyinstaller -F main.py
    5. Go into the venv\Lib\site-packages folder and copy the PyQt6 directory to the top level directory next to main.py and venv
    6. inside main.spec set the datas=[('./PyQt6', './PyQt6')]
    7. pyinstaller main.spec

    Once it compiles the executable should run. It pops a few warnings for me, but otherwise it does what its supposed too.
