  • converting audio from mp4 to wav and croping in the process using python

    7 mars 2019, par fastali

    I am looking for a package where I can use to convert the audio file from mp4 to wav simultaneously while also cropping the file using python.

    I have seen some posts about using ffmpeg to do the conversion but I dont seem to be able to run ffmpeg within python, and when converted to wav the files become around 10 times bigger which is kind of a storage issue.

    Does anyone have any suggestions except for pipelining it ?

  • ffmpeg won't start until java exits

    9 août 2014, par user3925332

    I am trying to make a java program that automatically converts wtv files in an input folder to mpg files in output folder. The twist is that I make it run periodically, so it acts as a synchronizer.

    The following code works for converting the .wtv to a .dvr-ms, which is required by ffmpeg since it cannot convert .wtv files directly.

        Process p = Runtime.getRuntime().exec("C:\\Windows\\ehome\\WTVConverter C:\\Users\\Andrew\\Desktop\\test\\input\\input.wtv C:\\Users\\Andrew\\Desktop\\test\\output\\input.dvr-ms");
    
    p.waitFor();

    WTVConverter has no problems running from a java application. ffmpeg is a different story. Once the above line runs, I then run this...

        Process p = Runtime.getRuntime().exec("ffmpeg\\bin\\ffmpeg -y -i \"C:\\Users\\Andrew\\Desktop\\test\\output\\input.dvr-ms'" -vcodec copy -acodec copy -f dvd \"C:\Users\Andrew\Desktop\test\output\input.mpg\"");
    
    p.waitFor();

    Suddenly, there is a problem... The application ffmpeg shows up in the task manager, but it’s cpu usage is 0, and no mpeg files is being generated. If I force the java application to close, though, suddenly it starts working ! Huh ?

    What reason would there be for a command line application to wait for its calling application to quit before it executes ? I’m not incredibly command line savvy, so I don’t really know how to diagnose this problem.

  • Problems encoding FLAC

    26 avril 2019, par aekio

    I’ve been following this example and have been able to encode a wav file to MP3. Now I want to try FLAC encoding.

    I have two problems.
    1. The FLAC file i create has no header metadata at all. How would I go about having that generated ?
    2. If I decode my FLAC file via command line I get a slightly distorted version of my original WAV file.

    shorthand of what I do :
    For Frame_size times I shift in two 16bit samples(S16 format) into Frame->Data[0] (32bit). Then call my normal encoding routine that’s been working for MP3 encoding.

    FFMPEG version 3.4.4-ubuntu stock package.

    Any ideas of where I might be taking a wrong turn ?
