  • How to read a MP3 audio file into a numpy array / save a numpy array to MP3 ?

    15 juin 2021, par Basj

    Is there a way to read/write a MP3 audio file into/from a numpy array with a similar API to scipy.io.wavfile.read and scipy.io.wavfile.write :

    



    sr, x = wavfile.read('test.wav')
wavfile.write('test2.wav', sr, x)


    



     ?

    



    Note : pydub's AudioSegment object doesn't give direct access to a numpy array.

    



    PS : I have already read Importing sound files into Python as NumPy arrays (alternatives to audiolab), tried all the answers, including those which requires to Popen ffmpeg and read the content from stdout pipe, etc. I have also read Trying to convert an mp3 file to a Numpy Array, and ffmpeg just hangs, etc., and tried the main answers, but there was no simple solution. After spending hours on this, I'm posting it here with "Answer your own question – share your knowledge, Q&A-style". I have also read How to create a numpy array from a pydub AudioSegment ? but this does not easily cover the multi channel case, etc.

    


  • ffmpeg (libav, libavfilter, etx) - modify frame with image or text using C\C++ API

    7 juillet 2023, par Alex

    After reading a huge bunch of docs and tutorials I still cant find a way to add some image or text to each frame of video. Something like logo on the frame corner, or text watermark.

    


    Iam know how to do such things with ffmpeg from cli, but for this case, C\C++ code is required.

    


    Looks like, ffmpeg's libav allow me to do some things with frame on decode stage, using AVFrame structure of current frame and add some modifications to it with libavfilter. But how exactly this can be done ?

    


  • Capture video on iOS device and live stream it to a server (or another mobile)

    13 février 2015, par theDuncs

    I want to be able to record footage using my iOS device and stream it directly to a server.

    There’s quite a few articles on S.O. that talk about this, but I’m not sure any have answered the question very well.

    Should I be using HTTP Live Streaming, or is this just for sending data to an iPhone ?
    Should I be using AVCaptureSession to grab the video (a segment at a time ?), sending each segment to the server ?
    Should I be using AVCaptureVideoDataOutput and ffmpeg for streaming ?

    I’m a little lost with all this, so any sample code or docs or links would be really appreciated.

    Thanks for your help guys.
