• Concatenating audio files and superimposing over video

  25 avril 2022, par kah

  I'm trying to write a program that takes a bunch of videos from a folder, compiles them, and then takes another bunch of audio files from a folder and concatenates them to then overlay the combined audio on top of the final video (hope that makes sense). I'm able to process the videos into one final output video, but I keep running into trouble combining the audio. Below I've provided two small sections of code pertaining to audio comp, I'm using moviepy to process the videos and attempting to use it for audio as well.

  


  songDirectory = './songs/'
songList = []
songs = []
audioclip=''

def makeCompilation():
    for filename in os.listdir(songDirectory):
        f = os.path.join(songDirectory, filename)
        if os.path.isfile(f) and filename.endswith(".mp3"):
            audioclip = moviepy.editor.AudioFileClip(f)
            songList.append(filename)


    for song in os.listdir(songDirectory):
        c = os.path.join(songDirectory, song)
    audio_clips = moviepy.editor.AudioFileClip(c)
    audio_output = moviepy.editor.concatenate_audioclips(audio_clips)
    finalClip = concatenate_videoclips(videos, method="compose")
    final_duration = finalClip.duration    
    final_audio_output = audio_output.set_duration(final_duration)
    final_output= finalClip.set_audio(final_audio_output).fx(afx.audio_fadein, 3.0)


    audio_path = "./songs/tempaudiofile.m4a"

    #print(description)
    # Create compilation
    final_output.write_videofile(outputFile, threads=8, temp_audiofile=audio_path, remove_temp=True, codec="libx264", audio_codec="aac")

    return description


  


  The program appeared to be able to find the audio directory, but I needed to be able to use os.path.join(songDirectory, filename) to point directly to each mp3 file so I messed around with it until I got the above code. And when I attempted to iterate through songList, I, as expected, got an error saying that 'str' wasn't iterable, and other errors saying that 'str' has no attribute 'duration'. Essentially, all I need it to do is iterate though the input folder and combine the files by whatever means. Code currently returns the output :

  


  &#127794;Free Fredobagz x Aflacko x Flint type beat - &#x27;Default_Dance&#x27; [prod. kah]-jro0v6ogZ0Y.mp4&#xA;225.05&#xA;Total Length: 225.05&#xA;225.05&#xA;Traceback (most recent call last):&#xA;  File "/Users/daddyK/Desktop/comp_ bot/make_compilation3.py", line 127, in <module>&#xA;makeCompilation(path = "./videos/",&#xA;  File "/Users/daddyK/Desktop/comp_ bot/make_compilation3.py", line 110, in makeCompilation&#xA;audio_output = moviepy.editor.concatenate_audioclips(audio_clips)&#xA;  File "/Users/daddyK/Library/Python/3.10/lib/python/site-packages/moviepy/audio/AudioClip.py", line 315, in concatenate_audioclips&#xA;durations = [c.duration for c in clips]&#xA;TypeError: &#x27;AudioFileClip&#x27; object is not iterable&#xA;</module>

  At this point I'm a bit stumped, so if anybody could offer some insight as to what I should do to resolve the error and/or if I'm headed in the right direction code-wise I'd greatly appreciate it ! Sorry if the code doesn't make any sense I'll post the whole .py file if needed

  


• I need help setting up a FFmpeg command that adds a small watermark in the bottom right of the first 5 seconds of multiple videos [closed]

  23 avril 2024, par hwm

  There are hundreds of videos that we'd like to add a small FFmpeg watermark to the bottom right during the first 5 seconds of each video. I don't know if there's a way to automate the command to all files in the folder, and if there is a way to make the output filename the same as the original video, or adding a -2 to the new filename. Some videos may have different file formats.

  


  Not sure if there's an app that can facilitate this for someone not well versed in programming, or can help do it to all the videos with one command. This could potentially be done in Linux, Windows or Mac. If the command changes based on OS, please let me know what the process would be for that specific OS.

  


  This is for a large project we are planning on releasing for free to the public fan space. Thanks !

  


  I can likely find someone that's more competent than me but getting the full command line to make this seamless would be ideal.

  


• How to match two audio files ?

  24 novembre 2014, par Janak Prajapati

  I am trying to develop script which compares two audio file.

  Lets say this is two audio music file recorded by Artist

  file1 : it is original song sung by an artist (Uploaded by admin)
  file2 : it is a file recorded by user. i.e user sings it and upload it to server

  now i want to check how closes is file2 to file1.

  Means i need to check if both songs match or not in terms of Lyrics, singing and all.

  I have searched many thing like audio fingerprinting , ffmpeg library and all it did not worked for me.

  I will go for any web technology you suggest.

  Please help me to find solution.

  Thanks.
