Ffmpeg command line issues on android

I managed to build ffmpeg Static build. But when I try to call the ffmpeg command line, I get Java IOException: there is no such file or directory.

My code is as follows:

public void merge_video(View view){ if(ffmpeg_file.exists()){ Log.d(null, "ffmpeg exists"); }else{ Log.d(null, "Could not locate ffmpeg in the folder"); } File file1 = new File("/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_22.mp4"); if(file1.exists()){ Log.d(null,"File 1 exists"); } File file2 = new File("/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_28.mp4"); if(file2.exists()){ Log.d(null,"File 2 exists"); } String[] ffmpegCommand = new String[5]; ffmpegCommand[0] = "/mnt/sdcard/com.ffmpeg_test/ffmpeg"; ffmpegCommand[1] = "-i"; ffmpegCommand[2] = "concat:/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_22.mp4|/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_28.mp4"; ffmpegCommand[3] = "copy"; ffmpegCommand[4] = "/mnt/sdcard/com.ffmpeg_test/output.mp4"; try { Process ffmpegProcess = new ProcessBuilder(ffmpegCommand).redirectErrorStream(true).start(); String line; BufferedReader reader = new BufferedReader(new InputStreamReader(ffmpegProcess.getInputStream())); Log.d(null, "*******Starting FFMPEG"); while((line = reader.readLine())!=null){ Log.d(null, "***"+line+"***"); } Log.d(null,"****ending FFMPEG****"); } catch (IOException e) { e.printStackTrace(); } }

The LogCat listing is as follows:

Android has a special security feature: the / mnt / sdcard file system is protected from execution. You cannot run an executable file that is located on external storage (aka USB storage). If you want to run the ffmpeg binary on your device, you must download it to one of the internal directories. For example, you can pack it in the libs / armeabi of your Java project so that the installer automatically unpacks it in the / data / data / <your package> / lib folder on the device. Or you can find another directory, for example / data / local , where you can put the binary executable with adb push
