  • FFMpeg - add background music

    20 mars 2016, par jacky brown

    here is what i have :
    input1.avi - video that contain sounds.
    input2.avi - video that doesn’t contain sounds.
    music.mp3 - audio file.

    i want to add background music(music.mp3 file) to the video.

    C:\input1.avi -i C:\music.mp3 -shortest -c:v copy -c:a copy C:\output1.avi

    then output1.avi is the same as input1 - movie with sounds but without the background music (music.mp3)

    when i try to use the other file (video without sounds) :

    C:\input2.avi -i C:\music.mp3 -shortest -c:v copy -c:a copy C:\output2.avi

    then output2.avi is the same as input2 + it have the background music.

    so why input1 does not contain the background music ???
    and how can i decrease or increase the volume of music.mp3 file ?

    thanks.

  • Is it possible to use dex2jar converted jar file into your project

    15 septembre 2012, par swapnil adsure

    i want to use ffmpeg decoder for my android project but i am having lots of error and config problem to compile it.
    but today i read about apk recompiling by dex2jar.
    so My question is " it is possible to use that dex2jar.jar file into your project ?.
    Like is it possible for me to use ffmpeg decoder into my project by importing that jar file into my project ?.
    and same case with vitamio plugin . so if it is possible than i just need to add that plugin jar into my project and link with code and user dont need to download extra plugin.
    waiting for reply

    thank you
