• 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));
  
      }
  
    }
  
  });

• Android ffmpeg adb shell Unknown encoder 'libx264'

  25 novembre 2017, par IChp

  When I run ffmpeg on android by adb shell, it shows this error :

   Duration: 00:00:12.00, start: 0.000000, bitrate: 30412 kb/s Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p, 352x288, 30412 kb/s, 25 tbr, 25 tbn, 25 tbc
  
  [4;31mUnknown encoder 'libx264'

  I don’t understand what went wrong. It bothered me for a lot of days.
  Can you help me out ? Thanks in advance !
  

  (I pushed the compiled libffmpeg.so to /system/lib and pushed ffmpeg to /system/bin)

  Target : compile ffmpeg with x264, and run libffmpeg.so on android device by adb shell.

  Compiled environment : Ubuntu16.0 32bit,ndk r10b 32bit platform 15, ffmpeg 3.0,x264 latest.
