• how to host live stream video

  21 août 2015, par Vhanjan

  Using jwplayer with html5 users can watch videos online..
  just put the source where the video file is located,, and the users can play the video that easy..

  i also tried to put a live stream source, as i remember it is rts ://sampledomain.com/video.mp4,
  then jwplayer easily play that mp4 file..

  my question is
  how can i host this kind of file "rts ://sampledomain.com/video.mp4" using my web camera or hypercam3 as my video recorder.. and send it to jwplayer so the users can play live stream in the browser using jwplayer..

  any hint are appreciated, but thank you very much for step by step tutorials..

• Downloading a Few Seconds of Audio from a Youtube Video with ffmpeg and youtube-dl Results in [youtube] : No such file or directory error

  20 décembre 2018, par DrJessop

  Below is the program that I wrote :

  ffmpeg -ss 60 -t 10 -i $(youtube-dl -f 140 https://www.youtube.com/watch?v=kDCk3hLIVXo) output.mp3

  This is supposed to get 10 seconds of audio starting at the one minute mark of the video and write it to output.mp3. If I run the youtube-dl command separately, and then the ffmpeg command with the entire video audio as input, it works. But, I do not want to download the entire video as well as create a new file with only a few seconds of audio.

  In its current state, I am getting [youtube] : No such file or directory errors. Does anyone know how I can fix this and keep it in one line ?

• 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,                
  
              });
