  • Convert .mp3/.wav file into g729/amr/g711 codec file and vice versa using PJSIP

    19 septembre 2017, par NandhaKumar

    PJSIP is used for SIP Registering, audio/video Calling and supporting some other VoIP Call features. If you want to create an VoIP Application, you will create an application using their libraries.

    In this library, there are available lot of codecs and some of codecs are available as third party codecs and you can integrate into PJSIP library. Then you can able to support those codecs while calling another SIP user/client.

    Generally In mobile phones, the voice is record as audio file through
    mic and it has passed to PJSIP library. Then those codec/pjmedia library take care
    of other operations like converting into anyother codec format which
    they want to send.

    Instead of that, can we able to pass .mp3/.wav file into PJSIP library and convert it into codec files like .g729/.amr/.g711-u and vice versa

    I don’t about how codec conversion/codec engine internally works around.
    If you know about the codec conversion from .mp3 format is possible using PJSIP library, please suggest me how to solve this problem.

    Thanks in Advance !

  • How to determine which offsets changed in MP4 file after cutting a part of the MP4 file

    16 février 2021, par Muath

    This image displays each offset and the role of that offset in mp4 file.

    


    enter image description here

    


    And this is MP4 file viewed in Hex-Editor :

    


    enter image description here

    


    When cutting (as an example) first 60 seconds of that video or doing any cutting process, How can I know which offsets has been changed ?

    


  • No such file error using pydub on OSX with pycharm

    15 juillet 2020, par Michael Harrison

    My ultimate aim is to run the code snippet below on Lambda but as I was having difficulties, I tried running it on my mac. I get the same error running with python2.7 on OSX as I do when I run it on AWS lambda.

    


    The code is :

    


    from pydub import AudioSegment
import os

def test():
    print("Starting")

    files = [f for f in os.listdir('.') if os.path.isfile(f)]
    for f in files:
        print (f)

    sound = AudioSegment.from_mp3("test.mp3")

test()


    


    The output of the code from pycharm is :

    Is this actually a problem with pydub/ffmpeg/ffprobe, rather than the location of my mp3 file ? As I'm trying to package this project for Lambda, I've put executable versions of ffmpeg and ffprobe in the root of the project, rather than installed them to my OS. Before I did this, pydub complained that it couldn't find ffmpeg. It's now not complaining but, could I have chosen the wrong binary ?

    &#xA;

    Any ideas ?
