• I download audio files but in m3u8 format. How to convert to mp3 ?

  26 mai 2022, par Александр Кузнецов

  I download audio files but in m3u8 format. How to convert to mp3 ? tried with ffmpeg. But nothing is downloading at the output, and only some strange characters are visible in the console.

  


  def vk_music_get(login,password):

    vk_session = vk_api.VkApi(login=login, password=password)
    vk_session.auth(token_only=False)
    vk_session.get_api()
    vk_aud = vk_api.audio.VkAudio(vk_session)
    for i in vk_aud.get():
        print(i)
        music_name = i['artist']
        urllib.request.urlretrieve(i['url'], f'\\Users\\AlexK\\PycharmProjects\\MyArchive\\music_vk\\{music_name}.m3u8  ')
    print('VK Download Success! ^_^')


  


  When I try ffmpeg, I get these characters

  


  

  


• ffmpeg video download shows errors in log

  15 juin 2022, par PeterM

  i'm trying to download media (video) files from sharepoint (i have view access), but during the process i get several "Connection to tcp ://xxx.xxxxx.ms:443 failed : Error number -138 occurred" or "HTTP error 503 Service Unavailable" errors (see following screenshots : tcp error HTTP error 503 )

  


  i get more errors with the following parameters :

  


  ffmpeg -i "https://theURLtoTheManifestYouCopiedHere" -codec copy downloadedVideo.mp4


  


  less errors with :

  


  ffmpeg -re -vsync 1 -i "https://theURLtoTheManifestYouCopiedHere" -codec copy downloadedVideo.mp4


  


  the options suggested in this article didn't help : https://medium.com/intrasonics/robust-continuous-audio-recording-c1948895bb49

  


  the output video is ok, but sound seems to be missing occasionally (a few seconds worth)

  


  ffmpeg version used is 2022-06-12-git-4d45f5acbd-essentials_build-www.gyan.dev (executable for windows)

  


  any advice ?

  I found that the the link in the m3u8 file is a bmp file instead of mp4.

  


  Does it matter ????
Can anyone tell me how to download the mp4 video file ?

  


  Thank you for reading this !
