The problem is that your ffmpeg command is probably not really marked as executable in the android folder. Use "adb shell" to connect and then "ls -l /data/data/com.koder.testffmpeg/files/ffmpeg" to see if it is really exectuable — user1943734

You should use getBaseContext().getApplicationInfo().nativeLibraryDir instead of "/data/data/com.example.ffmpegnew/files/"

Give executable permission to ffmpeg like so:

chmod 700 ffmpeg

Try using this:

Process proc = null;
ProcessBuilder pb = new ProcessBuilder();
proc = pb.command("String...yourCommand")
                    .redirectErrorStream(true).start();
BufferedReader bReader = new BufferedReader(new InputStreamReader(
                    proc.getInputStream()));

This code work for me for get system wakelock details in android.may be this will useful to you.

You could combine above answers like this:

 Process p = Runtime.getRuntime().exec("chmod 700 "+getBaseContext().getApplicationInfo().nativeLibraryDir + "/ffmpeg ...");
