• Moviepy/FFMPEG error while writing file : Permission denied

  26 février 2024, par rodinaxcvi

  I am using Power Automate to try to run this powershell script "python3 %Directory%%FileName%" :

  


  What my code is supposed to do :

  


  

  1. Download a video from youtube

  


  2. Put small clips from a folder in bottom left

  


  3. Overwrite audio from downloaded Youtube video with new audio from a folder in the same directory (I am replacing the video's audio with an .mp3 of someone narrating something)

  


  


  ERROR CODE :

  


  OSError: \[Errno 32\] Broken pipe

MoviePy error: FFMPEG encountered the following error while writing file combined_video_1TEMP_MPY_wvf_snd.mp3:

b'combined_video_1TEMP_MPY_wvf_snd.mp3: Permission denied\\r\\n'


  


  Code Snippet that seems to be throwing up error (NOT FULL CODE) :

  


  # Combine ad clips with main video footage
def combine_videos(main_video_path, ad_video_paths, output_path, bottom_videos_folder, custom_audio_path):
    main_clip = VideoFileClip(main_video_path).subclip(0, 60)  # Keep the original aspect ratio

    main_clip = main_clip.resize(width=1920)  # Resize based on width
    if main_clip.size[1] > 1080:
        main_clip = main_clip.resize(height=1080)  # Resize based on height if it's still too tall

    main_clip_x = (1920 - main_clip.size[0]) / 2
    main_clip_y = (1080 - main_clip.size[1]) / 2
    main_clip = main_clip.set_position((main_clip_x, main_clip_y))

    ad_clip = concatenate_to_duration(ad_video_paths, 60, bottom_videos_folder)  # Assuming 60 seconds for the ad clip
    ad_clip = ad_clip.resize(width=250)  # Resize the ad clip
    ad_clip = ad_clip.set_position(("left", "bottom"))  # Position the ad clip at the bottom right

    custom_audio = AudioFileClip(custom_audio_path)

    # Specify the output directory for the audio file
    output_audio_directory = "C:/Temp/AIContentCreator"
    output_audio_path = os.path.join(output_audio_directory, "custom_audio.mp3")

    # Write the custom audio to the specified directory
    custom_audio.write_audiofile(output_audio_path)

    main_clip = main_clip.set_audio(custom_audio)

    final_clip = CompositeVideoClip([main_clip, ad_clip], size=(1920, 1080))
    final_clip.write_videofile(output_path, fps=30)

    main_clip.close()
    ad_clip.close()
    custom_audio.close()

## SAVE PATHS ##
# Video Folder Paths
save_path = r"C:\Temp\Videos\YoutubeVideo"
bottom_videos_folder = r"C:\Temp\Videos\BottomVideo"
custom_audio_path = r"C:\Temp\AIContentCreator\GPTContentCreation\output.mp3"  # Existing audio file path

# Download videos from a playlist
playlist_url1 = ''
videos_playlist1 = download_playlist(playlist_url1, save_path)

# Prepare bottom videos

    # Call the combine_videos function with the existing custom_audio_path

    combined_video_counter += 1

  What I've tried :

  


  

  • Setting all related folders to full access

  


  • Setting full directory paths in my code

  


  • Running Power Automate and CMD as administrator

  


  • Moving files to a different folder like /Temp to see if permission error still consists

  


  


  Reoccurring problems :

  


  


  • I am not sure where MoviePy is writing "b'combined_video_1TEMP_MPY_wvf_snd.mp3". Could it be trying to place that file in another directory with out proper permissions ?

    


  


  • Whenever I try to de-select read-only on TiktokVideos folder and refresh it, "Read-only" is still on. Keeps doing this.

    


  


  


• aaccoder : rewrite PNS implementation

  6 septembre 2015, par Rostislav Pehlivanov

  aaccoder : rewrite PNS implementation
  This commit rewrites the PNS implementation and significantly
  
  improves sonic quality.
  The previous implementation marked an incredibly big amount
  
  of SFBs to predict when there was no need for this and this
  
  resulted in quite a large amount of artifacts. Also the
  
  quantization was incorrect (av_clip(4+log2f(...))) which
  
  led to 3x the intensity for PNS values leading to even more
  
  artifacts.
  This commit rewrites the PNS search function and introduces
  
  a major change : the PNS values are synthesized and are compared
  
  to the current coefficients in addition to passing through
  
  the revised checks to see whether PNS can be used.
  This decreases distortions and makes the current PNS implementation
  
  mainly focused on replacing any low-power non-zero bands as well
  
  as adding any zeroed bands back.
  The current encoder’s performance is enough (especially with
  
  IS) so PNS isn’t really required except to fill in the occasional
  
  few bands as well as extend any zeroed high frequency, so this
  
  combination which is already enabled by default works
  
  to get as much quality as it can within the bits allowed.

• ffmpeg itsoffset doesn't work with pcm audio and raw 264 video

  28 janvier 2019, par Danny

  I need to create an MP4 container with data from a hardware encoder. The encoder outputs PCM 16-bit signed audio and raw H.264 ES video frames.

  This ffmpeg command line I’ve got works but the audio and video are not sync’d.

  From other posts I know that itsoffset only works with video and probably doesn’t work with -v copy

  I’ve confirmed that applying an itsoffset has no effect.

  Here’s the command line. Any suggestions ?

  One post suggested itsoffset works if you re-encode the video. But doing that needs CPU power and adds latency. (And what’s the point of a hardware encoder then ?)

  ffmpeg -f s16le -ar 44.1k -ac 2      -i Audio_20190110-165736.pcm 
  
         -fflags +genpts -itsoffset -5 -i Video_20190110-165736.264
  
         -c:v copy -c:a aac -b:a 128k 
  
         -f mp4 -movflags +faststart  output.mp4

  EDIT I

  Here is a link to the audio/video input files referenced in the above command.
