• Youtube DL Unable to get local issuer certificate - CERTIFICATE_VERIFY_FAILED

  24 novembre 2022, par Casper Kristiansson

  I'm trying to use youtube DL with FFmpeg to download an m3u8 stream. Just recently I started receiving this error :

  


  ERROR: Unable to download webpage: <urlopen error="error" verify="verify" unable="unable" to="to" get="get" local="local" issuer="issuer" certificate="certificate">&#xA;(caused by URLError(SSLCertVerificationError(1,&#xA;&#x27;[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed:&#xA;unable to get local issuer certificate (_ssl.c:992)&#x27;)))&#xA;</urlopen>

  


  I know Youtube DL supports an option for nocheckcertificate but by enabling this after a couple of minutes the target machine will refuse the connection. When trying to use the same m3u8 stream on another computer, I could download the stream without any issues.

  


  I know that someone from Youtubedl CERTIFICATE_VERIFY_FAILED suggested fixing "your system's CA certificate list". What is the process of doing this ?

  


  I tried upgrading/reinstalling python and reinstalling the latest Windows update

  


  I also want to mention that there hasn't been any issue with downloading for the past year but recently stumbled upon this when switching proxy providers. But because the same setup works on another PC without any issue it's probably not the reason.

  


  The system the program is running on is Windows

  


  Edit : Another note is that downloading other public m3u8 streams works perfectly fine, so the problem is probably with the system CA SSL.

  


• How to combine/concatenate videos stored in AWS S3 bucket based on title of the file name

  9 juin 2020, par orangecube

  I am using a service that allows me to record videos that get automatically pushed to a folder (submissions) in an S3 bucket. There are multiple videos however they need to be grouped together and concatenated so the output is one video per group.

  



  So, basically, any tips on how I can take videos based on the title and stitch them together ?

  



  Example :

  



  Submissions folder will have :

  



  a-100-2.mp4
a-200-6.mp4
b-123-5.mp4


  



  Expected output in processed folder :

  



  a.mp4     - (both 'a' videos get stitched together)
b.mp4     - (only 'b' gets sent over since there is only one video.)


  



  Thanks in advance !

  



  Edit : Some additional and detailed information below if it helps.

  



  The files will be labeled with :
name-location-video_token-stream_token.mp4

  



  Need help creating a script or process that will concatenate the videos using the procedure outlined below :

  



  Processing rules (back end) :

  



  


  1. Check if videos have same video_token in ‘submissions folder’. If so, keep the newest one and delete old ones.

  


  2. Take all videos in ‘submissions folder’ with same name and location in title and concatenate the videos. Save output video to a new folder in the bucket labeled as the location for the folder name. 
Output file name : 
name-location-year.mp4.

  


  



  EXAMPLE :

  



  Submissions folder :
joey-toronto-001-354.mp4

  



  joey-toronto-001-241.mp4 - this will be deleted

  



  joey-toronto-103-452.mp4

  



  alex-montreal-352-232.mp4

  



  alex-montreal-452-223.mp4

  



  Resulting output :

  



  Toronto folder :

  



  Joey-toronto-2020.mp4

  



  Montreal folder :

  



  Alex-montreal-2020.mp4

  


• how to stop the FFmpeg process programmatically without using Ctrl + C ?

  30 septembre 2024, par bee

  const shell = require("shelljs");

const processShell = shell.exec(
  `ffmpeg -i "https://pull-hls-f16-va01.tiktokcdn.com/game/stream-2998228870023348312_or4/index.m3u8?expire=1728629296&session_id=000-2024092706481532076B1319E1100113F8&sign=1016b521d08053bc0ae8eddb0881b029" -movflags use_metadata_tags -map_metadata 0 -metadata title="Chill chill kiß║┐m k├¿o Warthunder" -metadata artist="bacgaucam" -metadata year="2024" -c copy "downloads/bacgaucam-927202491939.mp4" -n -stats -hide_banner -loglevel error`,
  { async: true }
);

setTimeout(() => {
  // processShell.kill();
  process.exit();
}, 20000);


  


  my video only works when I use Ctrl+C to stop it. I’ve tried using process.exit(), .kill(pid, "SIGINT"), and the .kill() method from the shell.exec() ffmpeg() of fluent-ffmpeg or spawn() of child_process reference, but none of them work

  


  If you want to test it directly, please message me to get a new live url in case it expires (https://t.me/ppnam15) or clone this :

  can anyone help ? Thanks !
