• 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

• ffmpeg loop through directory tree, output to identical tree in different root, only process files once

  22 juin 2020, par John M

  I would like ffmpeg to continuously loop through one directory structure looking for *.webm files and then convert them to mp4 when found, outputting them to an identical sub directory structure under a different path. Sub-directories/files are added to the tree automatically. I can do this manually, but my scripted attempts failed, I was using an ionotify event script to look for the new directories and re-running the conversion script, but it will not run continuously. I also do not want to process a file again once it has been converted.

  


  I was using this invoked with each inotify :

  


  find /opt/media/ -name "t_str_*.webm" -exec bash -c \
'ffmpeg -loglevel panic -acodec libopus -i $0 -strict experimental -movflags faststart ${0/webm/mp4}' {} \;


  


  I have the following directory structure, the subdirectories are alphanumeric.

  


  Source :

  


  parent1
 - AAAAAA
   - file1.webm
 - BBBBBB
   - file2.webm
 - CCCCCC
   - file3.webm
 - ZZZZZZ
   - file4.webm


  


  Destination :

  


  parent2
 - AAAAAA
   - file1.mp4
 - BBBBBB
   - file2.mp4
 - CCCCCC
   - file3.mp4
 - ZZZZZZ
   - file4.mp4


  


  Any suggestions ?
