• Android - concatenate two videos

  4 décembre 2016, par Marc Plano-Lesay

  I’m trying to concatenate two videos on Android. I’m already using ffmpeg for other needs, but I’m using halfninja’s one, which is only 0.9. The 0.9 one doesn’t allow the following ways to do it :

  // filter_complex isn't recognized
  
  vk.run(new String[] {
  
          "ffmpeg",
  
          "-i",
  
          inputFile1,
  
          "-i",
  
          inputFile2,
  
          "-filter_complex",
  
          "'[0:1] [0:0] [1:1] [1:0] concat=n=2:v=1:a=1 [v] [a]'",
  
          "-map",
  
          "'[v]'",
  
          "-map",
  
          "'[a]'",
  
          outputFile
  
  });
  
  
  
  // Or, after converting the two videos to ts, trying to merge them: concat:file1.ts|file2.ts: No such file or directory
  
  vk.run(new String[] {
  
          "ffmpeg",
  
          "-i",
  
          "'concat:" + ts1 + "|" + ts2 + "'",
  
          "-vcodec",
  
          "copy",
  
          "-acodec",
  
          "copy",
  
          "-absf",
  
          "aac_adtstoasc",
  
          output
  
  });

  The third thing I tried is to use the concat demuxer explained here, which isn’t recognized with ffmpeg 0.9 either.

  Is there any way to concatenate two videos on Android with ffmpeg 0.9 (or another library) ?

  I’m trying to build ffmpeg library for android, using roman10 tutorial

  I am able to run build_android.sh script.. but its not creating that ‘android’ folder in my source/ffmpeg folder !!

  In my case i try ffmpeg 3.0.1 in Ubuntu 14.04 ; 64bit.

  In the command line

  ./build_android.sh : line 17 : —prefix=/home/Admin/Documents/android-ndk-r9b/sources/ffmpeg-3.0.1/android/arm : No such file or directory

  ./build_android.sh : line 19 : —enable-shared : command not found

  ./build_android.sh : line 49 : —extra-cflags=-Os -fpic -marm : command not found

  ./build_android.sh : line 51 : —extra-ldflags= : command not found

  why android folder doesn’t create,

  please someone can guide me to do this.

  Thanks for ur time.
