• create video editor error stream specifier [on hold]

  25 mai 2018, par Oussama

  I am a beginner in ffmpeg, and I started by creating a video editor, but I encountered an error while executing an ffmpeg command :

  ’Stream specifier’ ’ in filtergraph description .... matches no streams’

  Here is the command :

  ’ffmpeg -y -i icone1.jpg -i icone2.jpg -i icone3.jpg -i icone4.jpg -loop 1 -framerate 24 -t 5 -i image1.jpg -loop 1 -framerate 24 -t 5 -i image2.jpg -i song.mp3 -filter_complex " color=black@0:1365x701,format=yuva444p[c0] ; color=black@0:1365x701,format=yuva444p[c1] ; [c0][4]scale2ref[ct0][mv0] ; [c1][5]scale2ref[ct1][mv1] ; [ct0]setsar=1,split=2[t00][t01] ; [ct1]setsar=1,split=1[t10] ; [t00]drawtext=fontfile=’arial’:text=’azaazzaza’:fontcolor=red:fontsize=30[tfi00] ; [t01]drawtext=fontfile=’arial’:text=’drtgfh’:fontcolor=red:fontsize=30[tfi01] ; [t10]drawtext=fontfile=’arial’:text=’uygfdsdsqds’:fontcolor=blue:fontsize=30[tfi10] ; [mv0][tfi00]overlay=x=55.0000:y=12.0000:shortest=1[mv0] ; [mv0][tfi01]overlay=x=55.0000:y=12.0000:shortest=1[mv0] ; [mv1][tfi10]overlay=x=55.0000:y=55.0000:shortest=1[mv1] ; [0]scale=500:500,setsar=sar=1[img0] ; [1]scale=500:500,setsar=sar=1[img1] ; [2]scale=40:50,setsar=sar=1[img2] ; [3]scale=500:500,setsar=sar=1[img3] ; [mv0][img0]overlay=20.0000:20.0000[mv01] ; [mv01][img1]overlay=12.0000:12.0000[mv02] ; [mv1][img2]overlay=20.0000:12.0000[mv12] ; [mv12][img3]overlay=55.0000:12.0000[mv13] ; [mv02]scale=1280:720,setsar=sar=1[fram0] ; [mv13]scale=1280:720,setsar=sar=1[fram1] ; [5]atrim=duration=10[a1] ; [fram0][fram1]concat=n=2:v=1:a=0[all]" -map [all] -map [a1] video-8.mp4’

• Discord.js Music bot "TypeError" when playing audio with dispatcher

  21 février 2020, par Cole Perry

  I’m new to Discord.js and I’m trying to have the bot join a voice channel and play an audio file on my computer. I have been following this guide : https://discord.js.org/#/docs/main/stable/topics/voice . Here is the Index.js page :

  Colesbot.on('message', message=>{
  
      if (message.content === '/join') {
  
          // Only try to join the sender's voice channel if they are in one themselves
  
          if (message.member.voiceChannel) {
  
              message.member.voiceChannel.join().then(connection => {
  
                  message.reply('I have successfully connected to the channel!');
  
  
  
                  // To play a file, we need to give an absolute path to it
  
                  const dispatcher = connection.playFile('C:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\Assets\Glory.mp3');
  
  
  
                  dispatcher.on('end', () => {
  
                      // The song has finished
  
                      console.log('Finished playing!');
  
                    });
  
  
  
                  dispatcher.on('error', e => {
  
                      // Catch any errors that may arise
  
                      console.log(e);
  
                    });
  
  
  
                    dispatcher.setVolume(0.5); // Set the volume to 50%
  
              }).catch(console.log);
  
      } else {
  
          message.reply('You need to join a voice channel first!');
  
        }
  
      }
  
   });
  
  exports.run = (client, message, args) => {
  
      let user = message.mentions.users.first || message.author;
  
  }

  FFMPEG is installed and I have set the environment path for it. When I type FFMPEG in the command line I get the proper response.

  Some have said I need to install the ffmpeg binaries but when I run npm install ffmpeg-binaries I get an error message that is here

  So then I tried installing an older version and I’m now using ffmpeg-binaries@3.2.2-3 but when I type /join I get the error

  [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received type object

• Jupyter Notebook JSONDecodeError to open file

  25 février 2021, par potterykid

  Expected behavior :
open a mp3 with no error

  


  Actual behavior :
I used the script below,

  


  from pydub
import AudioSegment

  


  song = AudioSegment.from_mp3("audio.mp3")

  


  and there is a JSONDecodeError
