  • Is there a method to identify the audio channel layout ?

    2 septembre 2016, par Pony

    A video file has many channels, and each channel is contained in a stream, e.g.

    Is there a method to identify which stream represents the left channel, and which represent right channel, and so on.
    Thanks for reviewing my question.

  • librosa can't load wav file in aws lambda docker

    30 novembre 2022, par Luka Savic

    I have an AWS Lambda function created using Docker.
I have librosa installed, ffmpeg installed using the solution from this question : install ffmpeg on amazon ecr linux python

    


    I checked in a Lambda function with os.system("ffmpeg -version") and I managed to get valid output, stating different versions and parts of ffmpeg.

    


    Problem is that when I do librosa.load(wav_file) it gives the following error :

    


    /your/path/.venv/lib/python3.9/site-packages/librosa/util/decorators.py:88: UserWarning: PySoundFile failed. Trying audioread instead.
  return f(*args, **kwargs) 


    


    From what I've read, librosa should natively support .wav files, even without ffmpeg, and even though I have ffmpeg installed, it doesn't work.

    


    One more information, .wav file was downloaded, player, and loaded with librosa on my local PC without any problems. I tried also on different wav and mp3 files, and the problems were still there.
