This error is caused by a missing system library: libsndfile. PyVideoTrans requires libsndfile as a system dependency on macOS.

Solution:

  1. Install libsndfile via Homebrew:

    brew install libsndfile
  2. After installation, clean and reinstall Python dependencies inside your virtual environment to ensure soundfile can find the library:

    uv sync --reinstall-package soundfile

    (Or simply delete the venv and run uv sync again.)

  3. Restart pyVideoTrans.

If the error persists, ensure that the _soundfile_data folder inside soundfile package is correctly present (it should exist after reinstalling). Also verify that libsndfile.1.dylib is linked properly (Homebrew usually handles this).

Please consult the related documentation:
