• Smartly concatenating gopro mp4 files - file-001.mp4 + file-002.mp4

  12 décembre 2017, par molly78

  Hello much smarter than me people out there...

  I have a folder of GoPro files which I have already renamed using this awesome utility : https://github.com/kcha/gopro_renamer

  However, I now have a folder of 110 files which should make up about 50 continuous videos...

  Some of which have only filename-001.mp4 parts, some are filename-001.mp4 and filename-002.mp4 parts. It could go on an on to say 10 parts per video, for argument sake.

  I’d like to get a hand with a script that would scan the folder and then join all the parts together into a new file.

  In windows 10 I know I can do a simple

  copy /b "C:\Filename-001.mp4" + "C:\Filename-002.mp4" Filename.mp4

  Just a bit lost how to loop thru this scenario with a (python is fine) script. I do not wish to re-encode them, simply join the parts that correspond to the base filename.

  So go from files looking like

  filename1-001.mp4 - 87 MB
  
  filename2-001.mp4 - 100 MB
  
  filename2-002.mp4 - 100 MB
  
  filename2-003.mp4 - 22 MB
  
  filename3-001.mp4 - 100 MB
  
  filename3-002.mp4 - 34 MB

  after concatenating the parts it would look like :

  filename1.mp4 - 87 MB (nothing done other than rename)
  
  filename2.mp4 - 222 MB (all joined)
  
  filename3.mp4 - 134 MB (all joined)

  Your help is greatly appreciated.

• 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.

  


• 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 
  
    )
