• 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 ?
