• Mix 2 mp3 files with FFmpeg for adroid

  1er avril 2017, par Thankgod Richard

  I am developing something similar to a karaoke app. I have a sound file(beat) and a recorded file(voice) from android mediarecorder. I am trying to mix the two files to become one file that plays the same time. I have set up ffmpeg provided by writingminds and everything is working fine. I am not familiar with ffmpeg commands so searched for and got few commands that can achieve the task for me. This is the code i got :

    String files = "-i " + currentFile + " -i " + someFile.getAbsolutePath();
  
              String output = mFileName + "/recorded/test.mp3";
  
              String cmd = "ffmpeg "+files+
  
                      " -filter_complex \"aevalsrc=0:d=10[s1];[s1][1:a]concat=n=2:v=0:a=1[ac1];[0:a][ac1]amix[aout]\" -map [aout] -c:a libmp3lame " + output;

  But it not working. this is the error i got :

  I read some answers here saying it depends on the version of the ffmpeg your using. I am using the latest ffmpeg for android by writingminds.

• Compilation of x264 with newest libswscale and libavformat

  4 décembre 2016, par pcroland

  Yesterday I wanted to compile x264 myself because the latest binary on videolan is compiled without libswscale : link

  If I just use

  ./configure --enable-static --enable-shared

  then the binary will compile libswscale 3.1.101 and libavformat 56.40.101 from the libswscale-dev and libavformat-dev packages. If I clone FFmpeg’s git and use

  ./configure --enable-static --enable-shared --extra-cflags="-I$HOME/FFmpeg"

  the binary will have the latest libswscale and libavformat, but it wont work :

  pc@pcroland:~/bin$ ./x264 --version
  
  x264 0.148.2744 b97ae06
