• Cannot play audio from a link using a Discord Bot

  2 mars 2020, par Guilhermeffable

  I’m trying to code a bot so me and my friends can hear the local radio on our Discord Server but I’m having this error.

  This is part of my code, it’s the play.js file that handles the playback stuff.

  module.exports = (client,message) => {
  
  
  
  const voiceChannel = message.member.voiceChannel;
  
  const idChannel = voiceChannel.id;
  
  
  
  console.log(idChannel)
  
      //vê se o user está numa sala de voz
  
  if(!voiceChannel) {
  
      return message.channel.send("Precisas de estar num voice channel para usar este comando.")
  
  }
  
  const permissions = voiceChannel.permissionsFor(message.client.user);
  
  
  
   //vê se tem permissões para entrar na sala
  
  if(!permissions.has('CONNECT') || !permissions.has('SPEAK')) {
  
      return message.channel.send("Não tenho permissões para entrar nessa sala.")
  
  }
  
  
  
  voiceChannel.join()
  
      .then(connection => {
  
          console.log("Successfully connected.");
  
          connection.playStream('http://centova.radios.pt:8401/stream.mp3/1')
  
  }).catch(e =>{
  
      console.error(e);
  
  
  
  });

  }

  And this is the error I’m getting :

• FFMPEG when delaying audio

  16 mars 2023, par Peter

  So, basically I am taking intro main and out and combining them. I need the intro visual to end two seconds before the audio ends while the main starts to play.

  


  I get this error.
Filter trim:default has an unconnected output

  


  any suggestions on what I need to try would be great !

  


  ffmpeg -i "${intro}" -i "${temp}" -i "${outro}" -filter_complex \
  "[0:v]scale=${output_width}:${output_height},setsar=1/1[v0]; \
   [1:v]scale=${output_width}:${output_height},setsar=1/1[v1]; \
   [2:v]scale=${output_width}:${output_height},setsar=1/1[v2]; \
   [v0][0:a][v1][1:a][v2][2:a]concat=n=3:v=1:a=1[video][audio]" \
   -map "[video]" -map "[audio]" -filter_complex \

• Error concatenating two files with ffmpeg ubuntu

  3 janvier 2014, par Dan Ramos

  The following command works fine in OS X :

  ffmpeg -f concat -i videos_playlist.txt -c copy final.mkv

  But when I try to run it on ubuntu i get the following :

  Unknown input format: 'concat'

  Any idea what I'm missing or a possible work around ?
