• 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.

  


• JW Player can't play mp4 video downloaded from youtube

  20 janvier 2015, par kheya

  I have doenloaded am mp4 video using IE Realplayer plugin from youtube.
  https://www.youtube.com/watch?v=e3a80c5Ar3Y

  I have a test site on my local machine where I have HTML5 JW Player.

  I download the video and then play locally using realplay to see if it plays.
  I notice that not all mp4 downloads from youtube plays in Realplayer.
  The ones that play in Realplayer also play in JW Player on local website.
  But the mp4 files that don’t play in Realplayer also don’t play in JW player.

  This is the error I get in the player :
  the video playback was aborted due to a corruption problem or because the video used features your browser didnot support mylocalsite/xyz.mp4 undefined

  I tested IE, FF, Chrome. It works nowhere.

  Here is my jw player setup and html :

  <video src="mylocalsite/test.mp4" type="video/mp4" poster="mylocalsite/test.jpg" width="640" height="360"></video>

  player setup :

  var modes = '';
  
  var swfPath = '/content/jw/player.swf';
  
              if (navigator.userAgent.toLowerCase().match(/(android)/) || navigator.userAgent.toLowerCase().match(/(chrom)/)) {                
  
                  modes = [{ type: 'flash', src: swfPath }, { type: "html5"}];
  
              } else {
  
                  modes = [{ type: 'html5' }, { type: 'flash', src: swfPath }, { type: "download"}];
  
              }
  
  
  
  jwplayer('container').setup({                
  
                  'flashplayer': swfPath,                
  
                  'width': '640',
  
                  'height': '360',
  
                  'provider': 'video',
  
                  'modes': modes,

• Use FFMPEG to merge RTSP stream from 4 web cameras into a single mosaic stream to YouTube Live [duplicate]

  19 octobre 2020, par Richard West

  I'm trying to take a live RSTP feed from 4 different cameras and create a 2x2 tile mosaic video stream to push to YouTube Live.

  


  I have good results using the ofllowing comand for a single feed, but I have not have any luck in using some of the samples I have found for a 2x2 mosiac.

  


  Some of the camera feeds are 3840x2160 and others are 1920x1080. So I'm expecting that I will need to have some resize logic in place. I would be happy with a 1920x1080 output feed pushed to YouTube.

  


  My current, single camera command, which yields good results, is :

  


  ffmpeg -rtsp_transport tcp -i rtsp ://192.168.1.42:7447/xxxxxxxx -tune zerolatency -vcodec libx264 -pix_fmt + -c:v copy -c:a aac -strict experimental -f flv rtmp ://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx-xxxx

  


  If I could specific a single camera to pull sound from that would be awesome, but I'd also be happy with no sound if that is necessary.
