QUESTION

Convert from opus to ogg file using ffmpeg [python soundfile]

Asked 2021-Sep-27 at 16:16

I'm using python soundfile to audio files in one of my projects. I have a dataset that contains opus files.

python soundfile can not read opus files directly but can read ogg files. (https://github.com/bastibe/python-soundfile/issues/252)

How can I convert all the opus files to ogg files with ffmpeg?

I have tried the following command,

 ffmpeg -i test_file_2.opus -c:a libvorbis -b:a 16k test_file_2.ogg

But I get an error,

I'm using librosa right now for conversion, but this is extremely slow:

# converting opus to ogg files for reading audio files with python soundfile
from glob import glob
from tqdm import tqdm
import soundfile as sf 
import librosa
import os

for f in tqdm(glob("/Data/AUDIO_DATA/mls_dutch_opus/*/audio/*/*/*.opus") + glob("/Data/AUDIO_DATA/mls_german_opus/*/audio/*/*/*.opus")):
    audio, sr = librosa.load(f, res_type='kaiser_fast', sr = 16000)
    sf.write(f.replace(".opus", ".ogg"), audio, sr, format='ogg', subtype='vorbis')
    os.remove(f)
