• ffmpeg TCP connection refused trying to download m3u8 file

  21 mai 2021, par Cyeole

  I'm trying to download a .m3u8 stream and convert it to mp4. The code I'm using is :

  


  ffmpeg -i "http://v030.url/s/1/6/8/168192d4db9f6a2d0247784d11bd3aaa/stream/480p/index.m3u8?h=f676f54bc54d0a97a591fb5122c85cfb&e=1621581127" -c copy -bsf:a aac_adtstoasc outputname.mp4


  


  However, I'm getting this error :

  


  [tcp @ 0x7fbdda504900] Connection to tcp://v030.url:80 failed: Connection refused
http://v030.url/s/1/6/8/168192d4db9f6a2d0247784d11bd3aaa/stream/480p/index.m3u8?h=f676f54bc54d0a97a591fb5122c85cfb&e=1621581127: Connection refused


  


  If I directly go to the link, it downloads the .m3u8 file without any problems and I've tried to convert this but it fails to read segments from the site. If I remove the "h=" and "e=" the link doesn't allow me to access the file.

  


  Can someone please guide me on how to download this file in ffmpeg ? It seems like it's protected. Cheers !

  


  I'm using ffmpeg on Mac OS X.

  


• Download a part of youtube video using a powershell script

  26 octobre 2024, par Nguyễn Đức Minh

  I'm writing this Powershell script :

  


  $URL = "https://www.youtube.com/watch?v=KbuwueqEJL0"
$from = 00:06:15
$to = 00:09:17

$cmdOutput = (youtube-dl --get-url $URL) 

ffmpeg -ss $from -to $to -i  -ss $from -to $to -i  output.mkv


  


  This script's purpose is to download a part of a Youtube video. I've set the variable $URL to specify the Youtube URL, while $from and $to is the start and end time of the part I want to download.

  


  $cmdOutput is used to output the stream URL. The output would have two lines : the first one is the URL for the video stream, while the second one is the audio stream URL.

  


  Currently, I don't know how to use the output as a variable and specify the line number of $cmdOutput to put it into the correct stream. I guess and would be replaced by something like $cmdOutput[line 1], and $cmdOutput[line 2], though I know that those are incorrect.

  


  I've consulted this answer, and it is handy for me to write this script. I've also read Boris Lipschitz's answer on how to do the same thing with Python, but his answer does not work.

  


  In that script, the -ss flag inputs the seeking point, and the -t <duration></duration> flag tells FFmpeg to stop encoding after the specified duration. For example, if the start time is 00:02:00 and the duration is 00:03:00, FFmpeg would download from 00:02:00 to 00:05:00, which is not the expected outcome. For some reason, his Python script skips the first 5 seconds of output, even if I replace the -t flag with -to . I've tried to edit his script, but it does not work unless you explicitly specify the time for both video and audio stream, as well as their respective stream URL.

  


• Can not download a streamable m3u8 link with IDM and ffmpeg

  15 juillet 2021, par long

  This is the link : https://v13.phephim.xyz/vod/v2/packaged:mp4/6005b3591918ee01c9ef67e4/playlist.m3u8

  


  It's ok to play the link with play-hls-m3u8 chrome extension or by the site https://www.hlsplayer.net/ but I got errors when trying to download it by ffmpeg :

  


  ffmpeg -i https://v13.phephim.xyz/vod/v2/packaged:mp4/6005b3591918ee01c9ef67e4/playlist.m3u8 -c copy OUTPUT.MP4

  I have tried to add some other command options but still got the same errors.

  


  Doing devtools inspect, I found
the .ts segment link redirected to another link that has the response header :

  


  content-disposition: inline;filename="unnamed.png"
content-type: image/png


  


  Is it normal ?

  


  Image : response header

  


  Pls help me to download the video. Thanks !

  


  p/s : sorry for my bad english :)
