• Iterate recursively in every subfolder and run a batch file

  6 août 2018, par Gokul Nair

  Please look at the following scenario wherein a folder A has many subfolders with different names. These subfolders have n number of .jpg files, which I am trying to scale and crop.

  Folder A\
  
    SubFolder 01\*.jpg
  
    SubFolder 02\*.jpg
  
    .
  
    .
  
    .
  
    SubFolder xx\*.jpg

  These sub-folders are with different names and do not have a trend when it comes to its names.

  I have created a batch file which would scale and crop images. This is working perfectly. I need to run the following command (name of file : ScaleCrop.bat) in each SubFolder xx :

  for %%I in (.) do set CurrDirName=%%~nxI
  
  for %%a in ("*.JPG") do ffmpeg -i "%%a" -vf ^"scale=-1:260, crop=250:250^" "..\ScaledImages\%CurrDirName%\%%a.JPG"
  
  for %%a in ("*.JPG") do ffmpeg -i "%%a" -vf ^"scale=260:-1, crop=250:250^" "..\ScaledImages\%CurrDirName%\%%a.JPG"
  
  pause

  The command Scales and crops the image in the folder and saves these files in to a folder named SacledImages, which too has subfolders of the same name (SubFolder 01, SubFolder 02,…,SubFolderxx).

  I have created another .bat file which I used to copy ScaleCrop.bat to each subfolder.

  for /d %%a in ("C:\Users\Name\Desktop\Folder A\*") do copy " C:\Users\Name\Desktop\Folder A\ScaleCrop.bat" "%%a"

  How could I code a batch file run and execute ScaleCrop.bat from each of these subfolders ?

  I tried using the following code, but this just calls the .bat file inside each subfolder, however it is not executing :

  for /f %%f in ('dir /ad /b') do start %%f\ScaleCrop.bat

  I Tried the following as well, this does the trick, but all images are getting overwritten as the scaled-cropped images are saved on to /SacledImages Folder and not inside ScaledImages/SubFolderxx :

  for /r "C:\ Users\Name\Desktop\Folder A " %%a in (.) do (
  
    pushd %%a
  
  for %%I in (.) do set CurrDirName=%%~nxI
  
  for %%a in ("*.JPG") do ffmpeg -i "%%a" -vf ^"scale=-1:260, crop=250:250^" "..\ScaledImages\%CurrDirName%\%%a.JPG"
  
  for %%a in ("*.JPG") do ffmpeg -i "%%a" -vf ^"scale=260:-1, crop=250:250^" "..\ScaledImages\%CurrDirName%\%%a.JPG"
  
  pause
  
    popd 
  
    )

• How to embed ffmpeg and ffprobe to a python gui.exe file in Windows or Mac ?

  10 décembre 2023, par sburakc

  I prepared a Pyhton Gui script in Windows that gets a subtitle then converts an audio file. But at the end of the script I realized that the script uses the ffmpeg from my computer's local ffmpeg and didn't give any error. But, when I try in another computer that doesn't include ffmpeg, it's given the error in the terminal below :
pydub\utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work Processing text 1/2 pydub\utils.py:198: RuntimeWarning: Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work Error occurred: [WinError 2] System cannot find the specified file

  


  I tried many ways such as :

  


  pyinstaller -F --add-data "./ffmpeg/*;./ffmpeg/" gui.py

  


  pyinstaller -F --add-data "C:\Users\sbura\Desktop\gom\ffmpeg\ffmpeg.exe;ffmpeg" --add-data "C:\Users\sbura\Desktop\gom\ffmpeg\ffprobe.exe;ffmpeg" gui.py

  


  OR

  


  tried to gui.spec file adding :

  


  exe = EXE(pyz,
          a.scripts,
          binaries=[('C:\\Users\\sbura\\Desktop\\gom\\ffmpeg_bin\\ffmpeg.exe', 'ffmpeg.exe'), 
                    ('C:\\Users\\sbura\\Desktop\\gom\\ffmpeg_bin\\ffprobe.exe', 'ffprobe.exe')],
          a.zipfiles,
          a.datas,
          [],
          ...



  


  I also created a folder with the name of "ffmpeg" where I put the files of ffmpeg.exe and ffprobe.exe.

  


  Also I added to my code that :

  


  import sys
from pydub import AudioSegment

def resource_path(relative_path):
    if hasattr(sys, '_MEIPASS'):
        return os.path.join(sys._MEIPASS, relative_path)
    return os.path.join(os.path.abspath("."), relative_path)

AudioSegment.converter = resource_path('ffmpeg\\ffmpeg.exe')
AudioSegment.ffprobe = resource_path('ffmpeg\\ffprobe.exe')


  


  But any of these didn't work. Thank you for your help.

  


• Parsing file-like object into create_ffmpeg_player in discord.py not working

  3 août 2018, par user4757174

  The API documentation for create_ffmpeg_player says it allows passing file-like objects into create_ffmpeg_player as it will be passed to stdin.

  create_ffmpeg_player(filename, *, use_avconv=False, pipe=False, stderr=None, options=None, before_options=None, headers=None, after=None)

  filename – The filename that ffmpeg will take and convert to PCM bytes. If pipe is True then this is a file-like object that is passed to the stdin of ffmpeg

  here’s what I am inputting :

  buffer = BytesIO()
  
  c.setopt(c.WRITEDATA, buffer)
  
  c.perform()
  
  player = voice.create_ffmpeg_player(buffer,pipe=True)

  The PycURL object writes data to buffer which is the BytesIO object.

  Then I try to parse the file-like object into create_ffmpeg_player() but I get the following error :

      Traceback (most recent call last):
  
    File "C:\Users\user\AppData\Local\Programs\Python\Python36\lib\site-packages\discord\client.py", line 307, in _run_event
  
      yield from getattr(self, event)(*args, **kwargs)

      p2cread = msvcrt.get_osfhandle(stdin.fileno())
  
  io.UnsupportedOperation: fileno

  The error shows me that somewhere in the stack, a routine is trying to get the fileno() of the object, but since this is not a real file, there is no file handle, or "fileno". For a temporary work-around I am creating a physical file on disk and parsing that file into the function, but for this program, the function will be run many times so doing physical read/writes is not practical. Is it possible to work around this, or at least create a file on memory with the ability to get/spoof a fileno ?
