  • How can I get the volume of sound of a video in Python using moviepy ?

    15 juillet 2022, par IordanouGiannis

    I want to get the volume of sound of a video so I use the following :

    



    import numpy as np # for numerical operations
from moviepy.editor import VideoFileClip, concatenate

clip = VideoFileClip("soccer_game.mp4")
cut = lambda i: clip.audio.subclip(i,i+1).to_soundarray(fps=22000)
volume = lambda array: np.sqrt(((1.0*array)**2).mean())
volumes = [volume(cut(i)) for i in range(0,int(clip.audio.duration-2))] 


    



    But I get these errors :

    



    Exception AttributeError: "VideoFileClip instance has no attribute &#x27;reader&#x27;" in <bound method="method" of="of" instance="instance" at="at" 0x084c3198="0x084c3198">> ignored&#xA;&#xA;WindowsError: [Error 5] Access is denied&#xA;</bound>

    &#xA;&#xA;

    I am using IPython notebook and Python 2.7. &#xA;I assume something doesn't have the appropriate permissions. I have changed run this program as an administrator for ffmpeg.exe, ffplay.exe, ffprobe.exe.

  • ffmpeg concat videos with own audio and add a soundtrack 50% volume

    17 novembre 2020, par fedep11

    I have a list of file in a txt, I need to concat (files are same codec and size and have sound), than i need to add a soundtrack with 50% volume. Thanks

    &#xA;

    This is the command I use to concat but this substitute the audio with the new soundtrack, instead I need to mix with the original sound in the file, and I need to control the volume of the soundtrack.&#xA;ffmpeg -f concat -safe 0 -i "concat:file.txt" -i "soundtrack.mp3" -c copy "output.mp4"

    &#xA;
