  • Merging two audio files in Android using FFMPEG

    1er juillet 2021, par Jeremy

    I'm working on an application that takes two audio files, and merges them into the respected channels. The way they are being equalized are not as good as I had hoped, So I want to adjust the volume of each file during the mixing phase. I've seen a couple of examples online, like this, this, and [this][3].. but none of them are working for me. Can someone direct me in the right direction with this ? Much appreciation !

    



    I am using this library to execute : https://github.com/WritingMinds/ffmpeg-android-java

    



    Here is my code (EDIT)

    



    String files = "-i " + mVoiceFile.getAbsolutePath() + " -i " + mBeatFile.getAbsolutePath();
String filter = "-filter_complex [0:a]volume=0.99[a1];[1:a]volume=0.3[a2][a1][a2]amerge=inputs=2,volume=1.3,pan=stereo|c0

    



    enter code here

    



    and here are my errors from running.

    avfilter/buffersink : replace init_opaque by init
    

    The argument 'opaque' is always NULL since 0acf7e2 (2013),
    and avfilter_init_filter() was removed in 52067b3c0e (2016).
