• on PKG_CONFIG_PATH setting

  25 novembre 2016, par Kindermann

  I’ve installed ffmpeg on Ubuntu 16.04. Each time when I wanted to use pkg_config_path in a new terminal, I always had to type the following :

  export PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig"

  Is there a way where I can permanently set this path ?

• Strange error with ffmpeg and unoconv in python script

  27 mai 2015, par Avery Ripoll Crocker

  I am creating a python script that can be used by other people to convert files. However when I use this script I keep getting a weird error when I run the subprocess for unoconv, this error is :

  Traceback (most recent call last):
  
    File "conversion.py", line 15, in <module>
  
      check_call(["unoconv", "-f", Fileextension, filename])
  
    File "/usr/lib/python2.7/subprocess.py", line 540, in check_call
  
      raise CalledProcessError(retcode, cmd)
  
  subprocess.CalledProcessError: Command '['unoconv', '-f', '.pdf', 'journal.doc']' returned non-zero exit status 1
  
  </module>

  I have looked through various resources for this, but the one answer I have been receiving is that I must have set up the unoconv line incorrectly. I have checked several times that the code is correct, and it is. The other peculiar thing is that my code for ffmpeg works. Does anybody have an idea as to why this happens.

  Here is my program :

  print "If at any point you wish to quit the program hit Ctrl + C"
  
  
  
  filetype = raw_input("What kind of file would you like to convert? Audio, Image, Video or Document: ")
  
  
  
  if filetype == "Document":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .txt: ")
  
     from subprocess import check_call
  
     check_call(["unoconv", "-f", Fileextension, filename])
  
  
  
  elif filetype == "Audio":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .mp3: ")
  
     body, ext = os.path.splitext("filename")
  
     from subprocess import check_call
  
     check_call(["ffmpeg" ,"-i", filename, body + Fileextension])
  
  
  
  elif filetype == "Video":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .mp4: ")
  
     body, ext = os.path.splitext("filename")
  
     from subprocess import check_call
  
     check_call(["ffmpeg" ,"-i", filename, body + Fileextension])
  
  
  
  elif filetype == "Image":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .Jpeg: ")
  
     body, ext = os.path.splitext("filename")
  
     from subprocess import check_call    
  
     check_call(["ffmpeg" ,"-i", filename, body + Fileextension])

• FFmpeg with eclipse

  16 août 2020, par Cristian Jorge A. Kusch

  I'm having problems with eclipse and ffmpeg, there are false errors being detected by the IDE. I was able to compile without problems with the terminal, and no erros were detected, i'm using the last version of Ubuntu. I can also build it with eclipse, but i get a lot of false errors.
I cloned the repository from github and then selected makefile project with existing files, and i selected the gnu autotools toolchain for the indexer settings.
I was able to get it to build, but i had to run the ./configure command from the terminal first, otherwise i got this error makefile:167 : /tests/makefile : no such file or directory
So the issue i have is that even though it builds properly i get a huge ammount of errors like these :
