Can't read an image uploaded with st.file_uploader()

I get my hand on the new feature that we all have been waiting for.

I tested it to upload an image and read it with OpenCV (cv.VideoCapture) but unfortunately, I encounter an error. The type of the uploaded image is <_io.BytesIO object at 0x7f4c7adc7db0>

Error message

TypeError: an integer is required (got type _io.BytesIO)
  File "/usr/local/lib/python3.6/site-packages/streamlit/", line 324, in _run_script
    exec(code, module.__dict__)
  File "/workspaces/inveesion/", line 767, in <module>
    cap = Config().input_output_data(guiParam)
  File "/workspaces/inveesion/", line 508, in input_output_data
    cap = cv.VideoCapture(file_path)
