• Android Ffmpeg- Root Permission not granted to "su" Working Directory:null

  24 juillet 2015, par Workaholic Er

  I have compiled ffmpeg for android using ndk r10e on os x but it does not produce ffmpeg.so. All other libraries are generated. I have been searching this for over a week. I have tried various methods to execute ffmpeg command but none were successful. I used

  Process p=new ProcessBuilder("su /data/data/com.example.ffmpegtem/").start();
  
  
  
  Process p = Runtime.getRuntime().exec(
  
                  getBaseContext().getApplicationInfo().nativeLibraryDir); 
  
  
  
  Process p = Runtime.getRuntime().exec(Environment.getExternalStorageDirectory().getPath()); 
  
  Process p = Runtime.getRuntime().exec("chmod 700 /data/data/com.example.ffmpegtem/app_bin/ffmpeg");

  All resulted in IOException-Working Directory : null. I also tried Shell Callback method provided by Github android ffmpeg library project which resulted in Nullpointerexception. I have written read/write permission.

  Convert 1 image to video code :

  DataOutputStream os = new DataOutputStream(chperm.getOutputStream());
  
  os.writeBytes("-loop 1 -i " + inpath + " -c:v libx264 -t 15 -pix_fmt yuv420p -vf scale=320:240 "+outpath);

  What am I doing wrong ? Please help
