• Unable to run a program in PATH from Java code

  17 novembre 2012, par user1831004

  I am developing a Red5 media server application on a Mac (Dynamic Web Project in Eclipse). The app has to invoke FFMPEG to convert the video to a different format.

  I added "/Applications/FFMPEG" to PATH variable by running the following command in Terminal :

  echo 'export PATH=/Applications/FFMPEG:$PATH' >> ~/.profile

  When I invoke FFMPEG from terminal, it works fine. However, every time I run it from Java code with :

  Process p = Runtime.getRuntime().exec("ffmpeg");
  
  p.waitFor();

  I get the following error :

  Cannot run program "ffmpeg": error=2, No such file or directory

  I thought this might be a security limitation specific to the type of project, but even a simple Java program produces the same result. What am I missing ?

  ---

  Changing "ffmpeg" to full path of the application works, but I don't want to upload FFMPEG into the same directory as Red5 on a production server.

• what is the exact path to specify in php for ffmpeg for windows

  17 janvier 2014, par user3196597

  i'm new to ffmpeg..and i've been trying to figure out the exact path to specify while running it in a php exec() function the code below runs fine in terminal but not in php :

     1)c:/ffmpeg/bin/ffmpeg -y -i c:/xampp/htdocs/video/media/original.mp4 -f avi c:/xampp/htdocs/video/media/new.avi 2<&1
  
  
  
  
  
     2)c:/xampp/htdocs/video/ffmpeg/bin/ffmpeg.exe -y -i c:/xampp/htdocs/video/media/original.mp4 -f avi c:/xampp/htdocs/video/media/new.avi 2<&1

  that works fine in terminal but not in php, i think the problem is with the path specification..can anyone tell the exact path to use while working in windows,please ??

  thanks in advance friends :D

• ffmpeg permission denied though the user has permission

  12 octobre 2014, par codename_subho

  I have installed ffmpeg in my server running ubuntu 14. my flask app project root is at /var/www/project/
  i am able to upload files and my python scripts are able to write new files, but when i run ffmpeg in my script it gives permission denied.
  Also running the below line in terminal

  ffmpeg -i path/to/inputfile /path/to/outputfile & ps aux | grep ffmpeg 
  
  
  
  gives the user running the process is "ubuntu" which has write access to the project folder and its subfolders. As i told you other python script run by user "ubuntu" is able to create file.

  permission denied error happens in both cases(python script and directly in terminal)

  update :
  also looking at the confusion with the permissions, is there a way i can run the app from /home/ubuntu/project instead of /var/www/project. i am using mod_wsgi with apache for my flask-app.
