• "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 ??

  


• FFMPEG creating mp3 with "Junk" at the end

  13 juillet 2022, par Johnaras

  I have a web application which converts WebM files to mp3 using FFMPEG.js in the Client-Side. Once the mp3 conversion finishes, users are prompted to download their file.

  


  Lately, I realized that a lot of mp3 files which I tried to converted have a different duration value than the original WebM file. The duration is usually longer. For instance, a WebM file with duration of 2:16 gets converted to an mp3 file with a duration of 2:29. Once the player reaches at 2:16 it just goes back to the start.

  


  I have tried to open the file in Audacity but it keeps saying that this MP3 file seems to be "Malformed".

  


  I also tried to use MP3val and it says the file has junk at the end.

  


  Code Snippets :

  


  const worker = new Worker("/ffmpeg-worker-mp4.js");
import { fetchFile } from "@ffmpeg/ffmpeg"; // https://www.npmjs.com/package/@ffmpeg/ffmpeg

const convertSong = async (title, id, bitrate) => {
    setProgress("Initializing...")
    ffmpegVars = [title]
    
    worker.postMessage({
      type: "run",
      arguments: ["-i", `input.webm`, "-c:a", "libmp3lame",  "-vn", "-ab", `${bitrate ? bitrate : 256}k`, "-ar", "44100", "-f", "mp3", `output.mp3`],
      MEMFS: [{ name: "input.webm", data: await fetchFile(`/api/download/stream?video=${id}`) }]
    });
}

convertSong(data.title, data.id, data.bitrate)


  


  I'm literally willing to pay anyone who helps me fix this.

  


• libavutil/hwcontext_qsv : Align width and heigh when download qsv frame

  6 avril 2022, par Wenbin Chen

  libavutil/hwcontext_qsv : Align width and heigh when download qsv frame
  The width and height for qsv frame to download need to be
  
  aligned with 16. Add the alignment operation.
  
  Now the following command works :
  
  ffmpeg -hwaccel qsv -f rawvideo -s 1920x1080 -pix_fmt yuv420p -i \
  
  input.yuv -vf "hwupload=extra_hw_frames=16,format=qsv,hwdownload, \
  
  format=nv12" -f null -
