Convert from oga to mp3 using pydub: ffmpeg returned error code: 1

Question

I want to take an OGA file within a binary stream and convert it into mp3 using also another stream. I'm getting a permissions error even with running VSCode as administrator. This is my code:

from pydub import AudioSegment
AudioSegment.converter = "C:\\ProgramData\\chocolatey\\lib\\ffmpeg\\tools\\ffmpeg\\bin\\ffmpeg.exe"

input_stream = io.BytesIO()
input_stream.seek(0) 
await new_file.download_to_memory(input_stream)
 
# Create an audio segment from the binary stream
audio = AudioSegment.from_file(input_stream, format='ogg')

# Create an output stream for the MP3 data
output_stream = io.BytesIO()

# Export the audio to MP3 using ffmpeg and write the output to the stream
audio.export(output_stream, format='mp3', codec='libmp3lame')

# Get the MP3 data from the output stream
mp3_data = output_stream.getvalue()

Error message:

I ran the command in a terminal and the file converted without an issue:

ffmpeg -i .\file_12.oga output.mp3

I'm not sure if the .exe file must be included into the path. When I don't do it, What I get is a permissions error.
What other codecs can be used here?
Is it possible to use oga files? I tried to declare this but I got an 'Unknown input format: 'oga' message (audio = AudioSegment.from_file(input_stream, format='oga'))

Thanks!

UPDATE: I created a more simple version that is not using a binary stream and worked like a charm, so we know for sure that something is happening with the BytesIO object

async def voice_to_text(update: Update, context: ContextTypes.DEFAULT_TYPE) -> None:
    # Get the absolute path of the script
    filename = 'file_9.oga'
    script_dir = os.path.dirname(os.path.abspath(__file__))

    # Construct the file paths for input and output files
    input_file_path = os.path.join(script_dir, filename)
    output_file_path = os.path.join(script_dir, os.path.splitext(filename)[0] + ".mp3")

    # Load the OGA audio file
    audio = AudioSegment.from_file(input_file_path, format='ogg')

    # Export the audio to MP3 format
    audio.export(output_file_path, format='mp3')

    print("Conversion complete. MP3 file saved as:", output_file_path)

UPDATE 2: It seems like await new_file.download_to_memory(input_stream) is the problematic line. I tried to save the file and its corrupt. Not sure how to use this method then.
