• How do I playback .m4s files. And turn them into a binary stream for a Discord Bot

  30 octobre 2020, par Harvey

  I want to download the BBC radio 2 and stream it to a discord server. Each request is https://as-dash-uk-live.akamaized.net/pool_904/live/uk/bbc_radio_two/bbc_radio_two.isml/dash/bbc_radio_two-audio=320000-250636302.m4s However the Time stamp will change and they regularly delete content. I found a .dash file as well https://as-dash-uk-live.akamaized.net/pool_904/live/uk/bbc_radio_two/bbc_radio_two.isml/dash/bbc_radio_two-audio=320000.dash which is seems to request. However I can't find how to send it through a discord bot to a discord server. My code is

  


  const axios = require('axios')


module.exports = {
    play: async function (guild,message) {
        const serverQueue = {};
        const voiceChannel = message.member.voice.channel
        serverQueue.connection = await voiceChannel.join();
        plays(guild)
        
        async function plays(guild) {
            let data1 = new Date(1353439725);
            let data2 = new Date(Date.now()/1000);
            console.log(`https://as-dash-uk-live.akamaized.net/pool_904/live/uk/bbc_radio_two/bbc_radio_two.isml/dash/bbc_radio_two-audio=320000-${Math.floor((data2 - data1))-4000}.m4s`)
            const dispatcher = serverQueue.connection.play((await axios.get(`https://as-dash-uk-live.akamaized.net/pool_904/live/uk/bbc_radio_two/bbc_radio_two.isml/dash/bbc_radio_two-audio=320000-${Math.floor((data2 - data1))-4000}.m4s`)).data)
                .on('finish', () => {
                    console.log('Music ended!');
                    plays(guild);
                    return
                })
                .on('error', error => {
                    console.error(error);
                    plays(guild);
                    return
                });
            dispatcher.setVolumeLogarithmic(serverQueue.volume / 5);
        }
    }
}


  


  However no audio plays and the audio end event is always being called. Am I being really stupid or is there a way to do this.

• const command is not defined using ffmpeg and child_process

  19 avril 2021, par davidf214

  I'm doing a project and I have a problem. Im trying to generate a .mpd file for a VOD web. The problem is that when i upload a video, it gets me into the function but it says "const command is not defined".

  


  exports.encodeDash = (videoFile) => {
    return new Promise((resolve, reject) => {
      const parsedFile = path.parse(videoFile);
      const outputFile = `${parsedFile.name}.mpd`
      const outputFilePath = `/videos/dash/${outputFile}`;
      const outputFilemp4 = `${parsedFile.name}.mp4`;
      const outputFilePathmp4 = `/videos/${outputFilemp4}`

      if (parsedFile.ext == '.mp4'){
        let command=`ffmpeg -i ${videoFile} -c:v libx264 -r 24 -g 24 -b:v 1000k -maxrate 1000k -bufsize 2000k /videos/dash/${parsedFile.name}-1000k.mp4 && bento4/bin/mp4fragment --fragment-duration 2000 /videos/dash/${parsedFile.name}-1000k.mp4 /videos/dash/fragmentado/${parsedFile.name}_1000k-frag.mp4 &&

      } else {

      }    

                    
      // Encode
 
      
      child_process.exec(command, (err, stdout, stderr) => {
        if (err) {
          return reject(new Error(`Encoding error. ${stderr}`));
        }
        resolve(outputFilePath)
       
      });

   
    });
    
}


  


  Just in case, it gives me problems in line child_process.exec(command, (err, stdout, stderr). Thanks !
