• how to resolve error FileNotFoundError : [WinError 2] The system cannot find the file specified when using ffmpeg-python ?

  24 juillet 2021, par Geo

  I'm trying to merge video and audio files together using ffmprg but I keep on receiving this error

  


  ERROR :

  


  Traceback (most recent call last):&#xA;  File "C:\Users\Geo\youtubedownloader\test.py", line 9, in <module>&#xA;    ffmpeg.concat(video,audio, v=1 , a=1).output("C:/Users/Geo/output_video/mergedretweett.mp4/").run()&#xA;  File "C:\Users\Geo\AppData\Local\Programs\Python\Python39\lib\site-packages\ffmpeg\_run.py", line 313, in run&#xA;    process = run_async(&#xA;  File "C:\Users\Geo\AppData\Local\Programs\Python\Python39\lib\site-packages\ffmpeg\_run.py", line 284, in run_async&#xA;    return subprocess.Popen(&#xA;  File "C:\Users\Geo\AppData\Local\Programs\Python\Python39\lib\subprocess.py", line 947, in __init__&#xA;    self._execute_child(args, executable, preexec_fn, close_fds,&#xA;  File "C:\Users\Geo\AppData\Local\Programs\Python\Python39\lib\subprocess.py", line 1416, in _execute_child&#xA;    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,&#xA;FileNotFoundError: [WinError 2] The system cannot find the file specified&#xA;</module>

  


  Code :

  


  

video = ffmpeg.input("C:/Users/Geo/File.mp4")

audio = ffmpeg.input("C:/Users/Geo/File_audio.mp4")


ffmpeg.concat(video,audio, v=1 , a=1).output("C:/Users/Geo/output_video/outputvideo.mp4").run()```




  


• How To Convert Bit Rate (VBR) Of MP3 File Using PHP ?

  29 avril 2014, par Dave

  Using php, I am trying to convert and overwrite an mp3 file using the following command....doesn’t work.

  ffmpeg -i /Users/MacBookPro/Desktop/dragons.mp3 -ar 44100 -ab 128k -f mp3 /Users/MacBookPro/Desktop/dragons.mp3

  So even when I try the command from the terminal, the new mp3 file is only about 5 seconds (originally 3 minutes). What am I doing wrong & any ideas on how to get the command working ?

  Thanks in advance !

• How to run a ffmpeg command in python with file paths containing spaces ?

  21 juillet 2023, par tomatochan

  I'm developing a program in Python that requires the use of FFMPEG. In one step, I need to create a video from a text file containing the list of images (path and duration) that need to be assembled to make a video. To do this, I use the following code :

  


  cmd = [ffmpeg, "-y", "-f", "concat", "-safe", "0", "-i", tmp, "-c:v", "libx264", "-r", "25", "-pix_fmt", "yuv420p", out]
subprocess.run(cmd)
# os.system(" ".join(cmd)) # returns same error


  


  What returns the error : The syntax of the file, directory or volume name is incorrect.

  


  I know that paths can be problematic when they contain spaces, and as my username has one, I've taken care to quote the paths in such a way that :

  


  ffmpeg = "C:\Users\John Doe\Documents\ffmpeg\bin\ffmpeg.exe"
tmp = "C:\Users\John Doe\Desktop\path\to\file.txt"
out = "C:\Users\John Doe\Desktop\path\to\video.mp4"


  


  When I print(" ".join(cmd)), this is what I get in my terminal :

  


  "C:\Users\John Doe\Documentsffmpeg\binffmpeg.exe" -y -f concat -safe 0 -i "C:\Users\John Doe\Desktop\path\to\file.txt" -c:v libx264 -r 25 -pix_fmt yuv420p "C:\Users\John Doe\Desktop\path\to\video.mp4"


  


  However, the problem persists.
Has anyone ever had this problem and managed to solve it ?

  


  I've also tried the method where you have to escape the spaces (taking care to replace the \ with / and then the with \ ) but nothing works... The error persists.

  


  For your information, here are the contents of one of my .txt files

  


  file C:\Users\John Doe\Desktop\path\to\image_1.png
duration 0.04
file C:\Users\John Doe\Desktop\path\to\image_2.png
duration 0.04
file C:\Users\John Doe\Desktop\path\toimage_3.png
duration 0.04


  


  When I quote the paths in the .txt files

  


  

  • subprocess gives me the error :
PermissionError: [WinError 5] Access denied

  


  • os.system gives me the error :

  


  


  C:\Users\John' is not recognized as an internal or external command, an executable program or a command file.
The syntax of the file, directory or volume name is incorrect.
