• FFmpeg : The filename, directory name or volume label syntax is incorrect

  15 mai 2015, par m_pro_m

  I am making an app which auto-converts videos recorded from another program. I am trying to use command line to exec ffmpeg conversion. This is the command I am typing to the console :

  cmd /c "C:\Users\Mark\IdeaProjects\Converter\ffmpeg\ffmpeg.exe" -i "C:\Users\Mark\Videos\Arma 3\Arma 3 05.10.2015 - 16.27.24.06.DVR.mp4" -b:v 15M -y "C:\Users\Mark\Videos\Converted\Arma 3 05.10.2015 - 16.27.24.06.DVR.mp4.avi"

  It returns error message

  The filename, directory name or volume label syntax is incorrect

  If I run that command without cmd /c part, it works like it should. I also tried adding /s but without success.

  EDIT

  I solved the problem using Apache Commons library (Java) for executing commands in Command Line.

• running a .bat file using python

  26 octobre 2020, par Marius Blees

  I am working on a Youtube to mp4 converter and I currently have two webm files(one containing the audio and one containing the video) and a .bat programm that converts them into a webm file with audio and video. I tryed to open the .bat file using this code :

  


  import subprocess

subprocess.Popen(['C:/Users/mariu/Desktop/Youtube/a3.bat'])


  


  But when I run the code I get this Error :

  


  C:\Users\$$$\source\repos\Youtube Downloader\Youtube Downloader>ffmpeg -i 
C:/Users/$$$/Desktop/Youtube/1.webm -i C:/Users/$$$/Desktop/Youtube/2.webm -c copy 
C:/Users/$$$/Desktop/Youtube/output.webm
The command "ffmpeg" is either wrong or could not be found. (translated from german)


  


  The .bat programm works when I simply execute it but it doesnt when using Python. I have also tryed to use os.system("path") but that also didn't work. Help would be appreciated.

  


• Subtract a specific string from a variable in a for loop

  14 octobre 2020, par Filip

  I am making a file converter with batch using FFMPEG.

  


  I have encountered a problem when trying to subtract the name of a file from the complete link to the file to get the directory of the folder it is in so after the file is converted it can be put into that directory.

  


  Can someone advise me on how I could subtract the string from the filename variable from the string in the directory

  


  My code :

  


  @echo off
SETLOCAL ENABLEDELAYEDEXPANSION
set filetype=.flac
for /R %%a in ("*%filetype%*") do (
    set directory=%%a
    set filename=%%~na%filetype%
    set convdir=!directory:%filename%=!
    echo !convdir!
    pause
    ffmpeg -i "%%a" "convdir%%~na.wav"
    echo Converted %%a
)
echo Convertion Done!
pause
