• FileNotFoundError when extracting audio from recently saved video using FFMPEG"

  3 août 2023, par Peter Long

  Scenario : I'm using this tool to record tiktok live. I write another script to call the main.pytool because I want to add some additional options, for example, to extract the audio of the live video that is recorded
  

  


  FFMPEG is used to extract the audio. First the video is saved (with FFMPEG) and after I want to extract the audio of that video (again with FFMPEG). The path where the video is recorded and saved is C:\Users\Administrator\Desktop\tiktok

  


  The problem is that I see the file and it is saved, but this error is generated as output : FileNotFoundError: [WinError 2] The system cannot find the file specified

  


  I can't figure out why it doesn't detect the last saved video file in general

  


  I try with this

  


  import os
import subprocess
import time
from moviepy.editor import VideoFileClip

def main():
    # Command to run main.py and record the video
    cmd = 'python main.py -user ryzebenny -output "C:\\Users\\Administrator\\Desktop\\tiktok" -ffmpeg -duration 30 --auto-convert'
    subprocess.run(cmd, shell=True)

    # Wait for the video file to appear in the folder
    wait_for_video("C:\\Users\\Administrator\\Desktop\\tiktok")

    # Extract audio from recorded video
    video_filename = find_latest_file("C:\\Users\\Administrator\\Desktop\\tiktok", ".mp4")
    if video_filename:
        video_path = os.path.join("C:\\Users\\Administrator\\Desktop\\tiktok", video_filename)
        audio_filename = video_filename.replace(".mp4", ".mp3")
        audio_path = os.path.join("C:\\Users\\Administrator\\Desktop\\tiktok", audio_filename)

        video_clip = VideoFileClip(video_path)
        audio_clip = video_clip.audio
        audio_clip.write_audiofile(audio_path)
        audio_clip.close()
        video_clip.close()
        print(f"Audio extraction completed: {audio_filename}")
    else:
        print("No video files found.")

def wait_for_video(directory):
    max_wait_time = 60  # Maximum time to wait in seconds
    start_time = time.time()
    while time.time() - start_time < max_wait_time:
        if find_latest_file(directory, ".mp4"):
            break
        time.sleep(1)

def find_latest_file(directory, extension):
    list_of_files = [f for f in os.listdir(directory) if f.endswith(extension) and os.path.isfile(os.path.join(directory, f))]
    if list_of_files:
        return max(list_of_files, key=os.path.getctime)
    return None

if __name__ == "__main__":
    main()


  


  but i get this error

  Instead, I expect that once I save the video (in .mp4) the audio of that video will be extracted afterwards

  lavc/qsvenc_hevc : restore the default gop size
  commit a3c0a3e changed the default settings and expected the runtime can
  
  choose a best value. However the runtime doesn't set a valid gop size
  
  for hevc encoder, hence the output steam is non-seekable, which is
  
  inconvenient to user [1][2]

• Pydub : How to ave audio after convert it to aac ?

  4 août 2023, par suvodipMondal

  I am using django admin form to recieve a audio input, and I am trying to convert it into aac format with pydub.
I have installed ffmpeg in my system and also added pydub and ffmpeg-python as dependencies.

  


  Here is the django ModelAdmin :

  


  class AudioAdmin(admin.ModelAdmin):
    fields = ('file', 'bit_rate', 'format')
    list_display = ('id', 'file', 'bit_rate', 'format', 'content_type')

    def save_model(self, request, obj, form, change):
        audio_file = form.cleaned_data['file']
        _, file_extension = os.path.splitext(audio_file.name)
        curr_audio = AudioSegment.from_file(file=audio_file, format=file_extension.replace('.', ''))
        new_audio = curr_audio.export(out_f=audio_file.name, format="aac")
        obj.file = new_audio
        obj.save()



  


  I am still getting this error while converting an mp3 file in aac format.

  


      raise CouldntEncodeError(
pydub.exceptions.CouldntEncodeError: Encoding failed. ffmpeg/avlib returned error code: 1
