• Why can't we find the header file that actually exists ?

  15 décembre 2020, par zhukov18961201

  I am a C language beginners, I encountered a problem, can not find the header file, but in fact, these header files are in the current file, I saw online methods (for example : solution) are to add - I option can solve this problem, but I am very curious, why can't it find itself, can only rely on - I option ?

  ls .

• ffmpeg hundreds of videos- to-image as shell script in keyboard maestro

  28 juillet 2023, par Leopardi

  First I would like to say that I use MacOS, I am new using ffmpeg and keyboard maestro and have no little to none experience in coding. But I think I did learned a bit is the past few weeks trying to solve the problem I will ask now. Believe me I tried searching for answers online and did a lot of trial and error before coming here to ask my question.
so here is what I am trying to do :

  


  I have a folder (/Users/Documents/clips) with 450 short AVI clips (foto1.avi, foto2.avi...., foto450.avi) from which I would like to extract all frames from. I know how to extract all frames from 1 clip and copy them to an existing directory :

  


  *ffmpeg -i /Users/Documents/clips/foto1.avi /Users/Documents/Frames/Foto1/frame%06d.png *

  


  With their command all frames from the clip Foto1.avi (frame000001.png, frame000002.png...., frame000132.png) are copied to the folder /Foto1.

  


  With keyboard Maestro I created 450 folders named afters the 450 .avi clips.

  


  Is there a way to write a ffmpeg command that will extract the frames of all 450 .avi clips to the folder with the same name as the file ?

  


  I was hoping there would be a way of seeing variables in this kind of way :

  


  ffmpeg -i /Users/Documents/clips/foto%.avi /Users/Documents/Frames/Foto%/frame%06d.png

  


  I really appreciate any help. Thank you !

  


  I tried searching for answers in forums, ffmpeg database. And since I have almost no knowledge on coding sometimes is hard to decipher and understand the meaning of the code.

  


• No such file or directory : 'ffmpeg' in Django/Docker

  6 avril 2024, par tthheemmaannii

  I run my Django code in Docker. I run transcription software that requires ffmpeg to function. However I've been getting the error [Errno 2] No such file or directory: 'ffmpeg' whenever I try to run my code.

  


  Here's my views.py :

  


  def initiate_transcription(request, session_id):
    ...
                with open(file_path, 'rb') as f:
                    path_string = f.name
                    transcript = transcribe_file(path_string,audio_language, output_file_type)

   ...
