• Can't Install FFMPEG with homebrew

  6 mai 2021, par dcnaber

  I tried installing FFmpeg with homebrew today. When I enter "brew install FFmpeg" I get this :

  


  

  


  I tried running commands like brew doctor and git -C $(--repo homebrew/core)

  


  I'm using macOS Big Sur btw.

  


  EDIT : I installed FFmpeg as a final solution it seems to be working now. Thanks for helping, guys. I don't know what's wrong with my homebrew though.

  


• Random sounds in discord.js

  1er septembre 2020, par Audiophile

  I'm programming a discord bot using discord.js. I want to make a random sound player !
What am I doing wrong ? Can you help me ?

  



  case 'ps':
            var voiceChannel = message.member.voiceChannel
                voiceChannel.join().then(connection => {
                number = 5;
            var random = Math.floor (Math.random() * (number - 1 + 1 )) + 1;
            var rs = ( {files: [__dirname + '/Library/folder/' + "sound" + " (" + random + ")" + ".jpg"]} );
            const dispatcher = connection.playFile(rs);
                dispatcher.on('end', end => voiceChannel.leave());
            })
        break;


  



  There aren't any errors in terminal.

  


• FFMPEG concat video throws No Such Filter error

  5 janvier 2021, par Rohan Shah

  I am trying to concat three videos using FFMPEG,

  


  This is my command that I am executing using Java Runtime

  


      String command = "ffmpeg -i url_to_video -i url_to_video -i url_to_video -filter_complex [0:v] [0:a] [1:v] [1:a] [2:v] [2:a] concat=n=3:v=1:a=1 [v] [a] -map [v] -map [a] /home/rohan/output.mp4";

    Process process = Runtime.getRuntime().exec(command.split(" "));


  


  This is throwing me No Such Filter error, whereas if I try to run this via Terminal it works perfectly fine. I tried tweaking the cmd by removing or adding quotes, but any variant of this command that runs on terminal throws error in Java Runtime. While it runs perfectly on the Terminal.

  


  I have tried with Absolute paths and Amazon S3 URLs, while both of them work just fine in terminal, The S3 variant of command throws No Such Filter error and the Absolute path command throws a No Such File Or Directory error during Runtime.

  


  Here is the stack trace of the error

  


  Here is the standard error of the command (if any):
