• 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 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

  


  

  


• Download hls m3u8 stream with ffmpeg comes only with video - no audio

  20 avril 2022, par Arthur Meier

  I want to download a hls m3u8 stream from an internet source. I was able to get the video as mp4-file. But there is no audio. I've tried already serveral ffmpeg instructions in the windows terminal but with no success. I've change from power shell to cmd and use some of this

  


  ffmpeg -i https://dms.redbull.tv/v4/dms/media/stv/AAEJ0EHC58GGJY1D7GWS/640x360@971824/personal_computer/chrome/at/playlist.m3u8 -c:v copy -c:a copy -t 30 -bsf:a aac_adtstoasc output.mp4

  


  or

  


  ffmpeg.exe -i "https://dms.redbull.tv/v4/dms/media/stv/AAEJ0EHC58GGJY1D7GWS/640x360@971824/personal_computer/chrome/at/playlist.m3u8" -map -codec:a libmp3lame -b:a 96k -bsf:a aac_adtstoasc -c copy output.mp4

  


  The m3u8 addresses I've got using the browser tools for developers from firefox by searching in the network analysis.

  


  I also tried to get the video converted and saved with vlc - but also had no success. For the profile, I tried "Video - H.264 + MP3 (MP4)" with the setting "Keep original audio track". But also with other choices, I have had no success.

  


  I hope someone here has a working solution :-))
