• Stream MP4 over HTTP without segments

  23 novembre 2017, par Ben van Hartingsveldt

  I’m trying to stream MP4.

  If you stream MP3, you can stream it to something (maybe via RTMP or via IceCast) and watch it via HTTP (but no HLS). Your live MP3 file is something like : http://example.com/live.mp3. Here you can listen to live generated MP3.

  Now I want something simular with MP4.
  I want to stream MP4 (AVC/H.264) to a server (maybe via RTMP) and want to receive the livestream on this location : http://example.com/live.mp4.
  I don’t want to use HLS (with it’s M3U8 file and TS-files).

  Is this possible ?

  I know it works with a already generated MP4, after you converted it to a FastStart/WebOptimised MP4, but I want a LIVE mp4.

• Unknown issue with Discord.js and ytdl, completely skips playing audio

  21 novembre 2017, par Gman0064

  One of the commands I have for my Discord bot is to play a predefined music clip in the current user’s voice channel. The bot can connect, but rather than playing the song, it instantaneously leaves. I’ve tried using both connection.playStream as well as connection.playFile, and both seem to return the same (lack of) output. Am I missing some sort of dependency or is my code just written incorrectly ? Any help would be greatly appreciated !

  const Discord = require('discord.js');
  
  const ytdl = require('ytdl-core');
  
  const client = new Discord.Client();
  
  const streamOptions = { seek: 0, volume: 1};
  
  
  
  client.on('ready', () => {
  
    console.log('Login Success');
  
  });
  
  
  
  client.on('message', message => {
  
    if (message.content === '$vaporwave') {
  
      if (!message.guild) return;
  
      if(message.member.voiceChannel) {
  
        message.member.voiceChannel.join().then(connection => {
  
          console.log("joined channel");
  
          //const stream = ytdl('https://www.youtube.com/watch?v=cU8HrO7XuiE', { filter : 'audioonly' });
  
          const dispatcher = connection.playFile('./mcp420.mp3');
  
          //const dispatcher = connection.playStream(stream, streamOptions);
  
          dispatcher.on("end", end => {
  
            console.log("left channel");
  
            message.member.voiceChannel.leave();
  
          });
  
        }).catch(err => console.log(err));
  
      }
  
    }
  
  });

• Possible bug in latest google chrome (v62) ?

  21 novembre 2017, par Jalal El-Shaer

  The following demo was working perfectly :

  http://jsfiddle.net/r6wz0nz6/2/

  The following is a sample of ’video-preview’ class in action :

  <a href="https://www.youtube.com/watch?v=v1uyQZNg2vE" target="_blank" class="video-preview" data-frames="100" data-source="http://i.imgur.com/BX0pV4J.jpg">
  
  </a>

  Now, if you use your mouse to scroll from left-to-right, somehow it is not working (shows thumbnail instead of current image position). This was working perfectly before v62. While, from right-to-left, it works normally.

  Updated Please watch how this looks here : https://www.youtube.com/watch?v=HvDP-YXJgOk

  Question : How can I overcome this bug/issue ?

  P.S. the demo is based on this blog post (https://www.binpress.com/tutorial/how-to-generate-video-previews-with-ffmpeg/138)

  Update 2
  Interesting, in the following part :

  elm.mousemove(function(e) {
  
  var left = e.clientX - elm.position().left;
  
  slider.show().css('left', left -1); // <<---------------------- this line
  
  img.css('left', -Math.floor((left / width) * frames) * width);

  if I remove the ’-1’ like so :
  slider.show().css('left', left);
  It works from Left-To-Right, but now from Right-To-Left is showing same bug !!

  Proposed Workaround by @A. Wollf
  Change the "mouseout" to "mouseleave" and it seems to fix it : http://jsfiddle.net/r6wz0nz6/388
