How to get audio from mp4 using torchaudio

[zyjcsf]

Hi， when I run the preprocess_lrs2lrs3.py ， I got an error when 'audio_data = aud_dataloader.load_data(data_filename)' . It seem that the sox do not support the mp4 files, how can i to solve it ?

Thank you very much.

Hi @zyjcsf one solution for extracting audio is ffmpeg. There are multiple ways to install ffmpeg libraries. If you are using Anaconda Python distribution, conda install -c conda-forge ffmpeg will install compatible FFmpeg libraries.
