• FFMPEG Output Framecount Different On Audio Files PowerShell

  28 avril 2020, par ilham zacky

  I am using FFPROBE to get some file durations in PowerShell.

  



  For my video it gets the frame count properly but for my audio files it returns a different frame count.

  



  This is my code :

  



  $audioId = "$id.m4a"
$videoId = "$id.mp4"
$duration1 = ffprobe -i $videoId -show_frames 2>&1 | grep -c media_type=video
$duration2 = ffprobe -i $audioId -show_frames 2>&1 | grep -c media_type=audio
echo $duration1
echo $duration2



  



  For video it returns a proper output, but for audio it returns a wrong result.

  



  Any suggestions ?

  



  Thank you

  


• Error in Splitting Educational Videos into Segments Using Python (ffmpeg issue) [closed]

  28 décembre 2024, par Yahia Mohamed Hanbal

  I created a Python project to split long educational videos into smaller segments, each focused on a single question. The program uses OCR to detect text on video frames, identifies the word "Question," extracts the number following it, and splits the video whenever the number increases.

  


  here is the video i am tring to split ((video))

  


  Here’s an example of the program’s output :

  


  Video loaded: 14071 frames at 60 FPS, duration: 234.52s  
Frame 480, Time 8.00s, Question: 6  
...  
Frame 12360, Time 206.00s, Question: 7  
Creating segment 1: 8.00s to 206.00s  
Error: module 'ffmpeg' has no attribute 'Error'


  


  I’ve shared the full code in a GitHub repository for reference : Automated Video Scene Cutting.

  


  What the Program Does

  


  

  • Input : A long educational video.

  


  • Processing :

    

    • Detects text in each frame using OCR.

    


    • Searches for the word "Question" followed by a number.

    


    • Monitors when the number increases to identify segment boundaries.

    


    


  


  • Output : Creates video segments corresponding to individual questions.

  


  


  The Problem

  


  The program detects the questions and timestamps correctly, but when it tries to create the segments, I encounter the following error :

  


  Error: module 'ffmpeg' has no attribute 'Error'


  


  What I’ve Tried

  


  

  • Verified the ffmpeg-python library is installed (pip show ffmpeg-python confirms the installation).

  


  • Ensured the ffmpeg binary is accessible from the command line.

  


  • Reviewed the library documentation to ensure the correct usage of ffmpeg.

  


  • Tested with different video files to rule out input-specific issues.

  


  


  Environment Details

  


  

  • OS : Windows 11

  


  • Python Version : 3.9.13

  


  • Key Libraries : ffmpeg-python

  


  


  If anyone has insights into resolving this issue or suggestions for alternative approaches to handle this use case, I’d greatly appreciate your help.

  


  Thank you !
