• Update a connection to websocket in Meteor

  3 août 2017, par Lucas Carvalho

  I’m new in meteor and i want to create a video stream using JSMpeg and ffmpeg.

  With meteor, i can start a separeted server to receive the ffmpeg data and now i need to pass this data through a websocket connection for the clients logged in the server.

  How I can create this connection or how i can pass this data thru JSMpeg on the client side ?

  This is how i started the http server inside the meteor application :

  var http = require('http');
  
  
  
  var STREAM_PORT = 8081,
  
    WEBSOCKET_PORT = 8082,
  
    RECORD_STREAM = false;
  
  
  
  Meteor.startup(() => {
  
    // HTTP Server to accept incomming MPEG-TS Stream from ffmpeg
  
    var streamServer = http.createServer( function(request, response) {
  
      var params = request.url.substr(1).split('/');
  
  
  
      if (params.length != 3){
  
        console.log(
  
          'Failed Stream Connection: wrong number of parameters.'
  
        );
  
        response.end();
  
      }
  
  
  
      var userEmail = params[0];
  
  
  
      //here goes an function to get the user id
  
      var userID;
  
  
  
      var connName = userID + "-" + params[1] + "-" + params[2];
  
  
  
      response.connection.setTimeout(0);
  
      console.log(
  
        'Stream Connected: ' + 
  
        request.socket.remoteAddress + ':' +
  
        request.socket.remotePort, connName
  
      );
  
      request.on('data', function(data){
  
        //here i need to pass the data to an websocket
  
        socketServer.broadcast(connName, data);
  
        if (request.socket.recording) {
  
          request.socket.recording.write(data);
  
        }
  
      });
  
  
  
      // Record the stream to a local file?
  
      if (RECORD_STREAM) {
  
        var path = 'recordings/' + Date.now() + '.ts';
  
        request.socket.recording = fs.createWriteStream(path);
  
      }
  
    }).listen(STREAM_PORT);
  
  });

• Discord.py : Playing audio to voice channel speeds up

  7 juin 2021, par Toby

  I made a simple Discord bot using Discord.py to play short audio clips from local files and leave once it finished playing. The bot was working perfectly but now all the audio is getting sped up. I did not change anything in the code. There are a few audio clips that can be chosen, some are noticeably sped up while others don't even play sometimes. The speeding up is also inconsistent.

  


  Main Code

  


  @bot.event
async def on_ready():
    print('Logged in as {0.user}'.format(bot))

@bot.command()
async def meme(ctx, message):
    server = ctx.message.guild.name
    #check if user is in voice channel or if command is valid
    if not ctx.author.voice:
        return await ctx.send("Join a voice channel!") 
    else:
        if message in audioPathsDict:
            audioPath = audioPathsDict[message]
        else:
            return await ctx.send("Not a valid command!")
    #voice_channel is channel of command author
    voice_channel = ctx.message.author.voice.channel
    try:
        vc = await voice_channel.connect()
        print(f"Played {audioPath} in Voice Channel: {voice_channel}, Server: {server}\n")
    except:
        print("Already Connected to a voice channel")
    voice = discord.utils.get(bot.voice_clients,guild = ctx.guild)
    vc.play(FFmpegPCMAudio(audioPath))
    vc.source = discord.PCMVolumeTransformer(vc.source)
    vc.source.volume = 0.1
    while vc.is_playing():
        await sleep(2)#while audio is playing wait 0.5 then disconnect
    await vc.disconnect()


  


• ffmpeg exited with code 1 : Error configuring complex filters

  21 décembre 2015, par rycornell

  I am using the fluent-ffmpeg node package to merge videos. I am following the documentation exactly but I get the following error : Error: ffmpeg exited with code 1: Error configuring complex filters. Here is the code :

  ffmpeg('/videos/test/part1.mov')
  
    .input('/videos/test/part2.mov')
  
    .on('error', function(err) {
  
      console.log('An error occurred: ' + err.message);
  
    })
  
    .on('end', function() {
  
      console.log('Merging finished !');
  
    })
  
    .mergeToFile('videos/test/final.mp4', 'videos/test/tempDir');

  and here is the error output (I logged the command generated by fluent-ffmpeg to the console) :

  C:\Program Files\ffmpeg\bin\ffmpeg.exe [ '-formats' ] { captureStdout: true }
  
  C:\Program Files\ffmpeg\bin\ffmpeg.exe [ '-encoders' ] { captureStdout: true }

    '/videos/test/part1.mov',

    '-y',
  
    '-filter_complex',
  
    'concat=n=2:v=1:a=1',
  
    'videos/test/final.mp4' ] { niceness: 0 }

  I’m able to run ffmpeg on my machine for other tasks and it works fine. I’m not sure what the ’-filter_complex’ flag is supposed to do. I am using fluent-ffmpeg version 2.0.1 and ffmpeg windows static build git-9d1fb9e (2015-12-17).
