• Error while downloading video stream with streamlink + ffmpeg: Pipe copy aborted error

  29 November 2020, by beta

  I am trying to download a big video with the following command with Streamlink. Streamlink in the background uses ffmpeg. So what I get is actually an ffmpeg error.

  


  This is the command I use:

  


  streamlink --loglevel debug --hls-live-restart -o test.mp4 "https://aivottjab-a.akamaihd.net/IAD/jab-assets/jab-prod-iad/out/v1/732334e942a4465b8af9b21077d4e61d/cenc-083bb0.mpd?encoding=segmentBase&amznDtid=AOAGZA014O5RE" best


  


  This is the error I get after 26GB are downloaded.

  


  [19:48:27,437][stream.dash][debug] Download of segment: https://aivottjab-a.akamaihd.net/IAD/jab-assets/jab-prod-iad/out/v1/732334e942a4465b8af9b21077d4e61d/cenc_video_117_0_5791117.mp4 complete

  Anyone knows why this comes up?

  


  I am on Windows 10, Streamlink 1.7.0 and FFmpeg 4.3.1.

  


• Can I convert mp4 server file into a server as mp3?

  5 February 2021, by Andor Uhrin

  I'm working on an API which convert from video ID to mp3 or mp4. I use FFMPEG to convert. If I want to convert in mp3 first I download the video in mp4 then convert it to mp3 and upload it to Firebase storage. I want to make the fastest and I found the way where i download in mp4 and with ffmpeg the converted mp3 has uploaded to Firebase and this works fine and faster than the last version. The pafy streams have an attribute called 'url'. And I tried to put this url to base file's place so I don't download it just call it from the server. But this is doesn't work. I got this error:

  


  "
[https @ 0x564635880240] HTTP error 403 Forbidden
https://r3---sn-c0q7lnly.googlevideo.com/videoplayback?expire=1612548216: Server returned 403 Forbidden (access denied)
"
I know ffmpeg can convert from server, because I didn't get this error if it can't...

  


  This is my code:

  


  import pafy

import os


firebaseURL = f"https://firebasestorage.googleapis.com/v0/b/{my_firebase_app_id}.appspot.com/o/test.mp3"

vidID = "AQLEWWKv9n4"

ids = pafy.new(vidID).allstreams[-1].url

os.system(f"ffmpeg -i {ids} {firebaseURL}")
