• "fmpeg" has no attribute "input"

  2 mai 2024, par Robin Singh

  I had previously built this youtube downloader but when I tested it recently ; it stopped working.

  


  from pytube import YouTube
import ffmpeg
import os

raw = 'C:\ProgramData\ytChache'

path1 = 'C:\ProgramData\ytChache\Video\\'
path2 = 'C:\ProgramData\ytChache\Audio\\'

file_type = "mp4"

if os.path.exists(path1 and path2):
    boo = True
else:
    boo = False

while boo:

    url = str(input("Link : "))
    choice = int(input('Enter 1 for Only Audio and Enter 2 For Both Audio and Video \n: '))

    video = YouTube(url)
    Streams = video.streams

    if choice == 1:
        aud = Streams.filter(only_audio=True).first().download(path2)

    elif choice == 2:
        resol = str(input("Resolution : "))
        vid = Streams.filter(res=resol, file_extension=file_type).first().download(path1)
        aud = Streams.filter(only_audio=True).first().download(path2)

        file = video.title + '.mp4'
        # location = path1
        # location2 = path2
        rem = os.path.join(path1, file)
        rm = os.path.join(path2, file)

        video_stream = ffmpeg.input(path1, video.title + '.mp4')
        audio_stream = ffmpeg.input(path2, video.title + '.mp4')
        ffmpeg.output(audio_stream, video_stream, video.title + '.mp4').run()
        os.remove(rem)
        os.remove(rm)

    else:
        print('Invalid Selection')

if not boo:
    os.mkdir(raw)
    os.mkdir(path1)
    os.mkdir(path2)


  


  so it gives an error saying :

  


  Traceback (most recent call last):&#xA;  File "E:\dev files\YouTube Video Downloader\Video Downloader.py", line 39, in <module>&#xA;    video_stream = ffmpeg.input(path1 &#x2B; video.title &#x2B; &#x27;.mp4&#x27;)&#xA;AttributeError: module &#x27;ffmpeg&#x27; has no attribute &#x27;input&#x27;&#xA;</module>

  


  I can't figure out what happened. I think it may have something to do about the versions of ffmpeg or something ??

  


• avformat/hls : don't propagate deprecated "user-agent" AVOption

  28 avril 2018, par wm4

  avformat/hls : don't propagate deprecated "user-agent" AVOption
  This code will print a warning if any user agent is set - even if the
  
  API user used the proper non-deprecated "user_agent" option.
  This change should not even break anything, because even if the user
  
  sets the deprecated "user-agent" option, http.c copies it to the
  
  "user_agent" option anyway.

• Issue with yt-dlp and FFMPEG Converting Webm to MP4 for 360 video : Unsupported channel layout "ambisonic 1"

  22 janvier 2024, par William L W L

  I am trying to convert .webm files to mp4. These are 360 videos that have been downloaded using yt-dlp.

  


  I have been using this command successfully, but it does not work on an M2 macbook pro. It works fine on PC.

  


  ffmpeg -y -i "/Users/x/Movies/Tropical_Rainforest_360.webm" -c:v libx265 -preset fast -crf 21 -vf "scale=4096x4096:out_range=full" -pix_fmt yuvj420p -aspect 1:1 -movflags faststart "/Users/x/Movies/Tropical_Rainforest_360.mp4"


  


  The error messages are as follows :

  Context : I work in an educational setting which caters for vulnearble pupils. We cannot use Youtube in real time, this is mainly due to adverts or suggested videos that may trigger our pupils. Some children have mental health issues. Some children have also not been outdoors for several months/years due to medical conditions. We use 360 videos and VR to help bring the outside world inside, The YoutubeVR app is not an option since there is no way to install adblockers.

  


  The same script above works fine on a PC virtual machine which I can remote into from my Mac.
