• ffmpeg library does not work from path but directly

  19 juin 2020, par Ángel Barrios

  I want to add a watermark to a video.

  



  I'm trying with windows 10 and ffmpeg library

  



  The command I am using.

  



  ffmpeg -i example.mp4 -i watermark.png  -filter_complex "overlay=0-0+0:main_h-overlay_h-0+0" watermark.mp4


  



  When I use it this way accesing the path I get this error :

  



  

  



  But when I execute it not from path but opening cmd right on the executable folder it works fine

  



  I did some research and couldn't find the answers I was looking for.

  



  Why does this happen ? I can´t understand really

  



  Thank you !

  


• How to make ffmpeg follow a variable file path [closed]

  2 septembre 2023, par Wessie

  I have a little Python script. What it should do is to take the last file out a folder and convert it to another with the same filename.

  


  The Script :

  


  from moviepy.editor import *
import glob
import os.path

#Variabels
folder_path = r'/pathtofolder/Recordings'
file_type = r'/*h264'
file_type_conv = r'/*mp4'
files = glob.glob(folder_path + file_type)
files_conv = glob.glob(folder_path + file_type_conv)
clip_latest = max(files, key=os.path.getctime)
clip_conv = max(files_conv, key=os.path.getctime)

#print(clip_latest)
#print(clip_conv)

ffmpeg -i clip_latest -r 25 clip_conv 


  


  This gives me back :

  


  SyntaxError: invalid syntax


  


  When I 'print" the code it gives me the path I need. But I cannot get the path into the ffmpeg code.
What anm I doing wrong ?

  


  Thanks in advance !

  


  I tried to place the variables in "" and in {}.
When I give a full path it works good.

  


  UPDATE :

  


  Got it working ! Thaqnks to the advise of@Daviid I've used python-ffmpeg library.
Here's the code :

  


  import glob
import os.path
import subprocess

#Variabels
folder_path = r'/home/wessie/Halloween/Recordings'
file_type = r'/*h264'
file_type_conv = r'/*mp4'
files = glob.glob(folder_path + file_type)
files_conv = glob.glob(folder_path + file_type_conv)
clip_latest = max(files, key=os.path.getctime)
clip_conv = clip_latest + '.mp4'

print(clip_latest)
print(clip_conv)

subprocess.run(['ffmpeg', '-i', clip_latest, clip_conv])



  


  Thanks !

  


• Set path while installing [duplicate]

  12 janvier 2021, par Education 4Fun

  My requirement is to set a path(C :/ffmpeg) while installing the software itself for my application(which I made)
  
A reference that it's possible(While installing python 3.8.0 we have check box by ticking it we can add the path of python automatically)
  
This is the main requirement which I wanna do with my application

  


  

  


  About My application :
  
My application is a simple video editing application that runs on cmd as it uses FFmpeg its path should be set only then the application will work
The application is coded in python and the GUI is made using pyqt5 The application runs on cmd like the commands and all here is a reference image for observation enter image description here

  


  

  


  So it's mandatory to add the path else FFmpeg will not recognize. If there is any way to do in building setup like how python can add the path as per user requirement refer to the image (1st image)

  


  About Files in C :/ffmpeg
Files in FFmpeg folder refer to image for that info

  


  

  


  Hope the query is a bit clear.
Thanks a lot
