• Evolution #4727 : Des pictos / icônes symboliques pour tout le monde

  12 avril 2021, par nicod _

  Les fontes d’icônes c’est pas top, c’est un peu déprécié aujourd’hui, ça pose pas mal de problèmes.
  Mais si ça devait être utilisé, il faudrait des <span class="icone truc"></span> plutôt que des <i class="spicon_truc"></i>

  Et les gros fichiers de sprites svg, ça diminue le nombre de hits, c’est sûr, mais charger plusieurs centaines de Ko de Sprites pour afficher 3 icônes, c’est peut être beaucoup.
  Et c’est la misère à mettre à jour sans outil spécialisé qui regénère tout le code, et vérifier que ça ne casse pas des choses...

• 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 :

  TypeError [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received an instance of

• FileNotFoundError on aws Lambda when concatenating videos with ffmpeg

  2 juillet 2021, par Shibu Menon

  Goal :

  



  

  • Concat 2 videos (both are in an s3 bucket) via aws Lambda using ffmpeg

  


  • Upload the resultant output.mp4 to another S3 bucket

  


  • Python 3+

  


  



  I've already created a layer containing a static ffmpeg

  



  The Error :

  



  {
  "errorMessage": "[Errno 2] No such file or directory: '/tmp/output.mp4'",
  "errorType": "FileNotFoundError",
  "stackTrace": [
    [
      "/var/task/lambda_function.py",
      19,
      "lambda_handler",
      "s3.Object(bucketLowRes, mp4OutputFileName).put(Body=open(new_file_key, 'rb'))"
    ]
  ]
}


  



  My Lambda function :

  



  import json
import os
import subprocess
import boto3

s3 = boto3.resource('s3')
bucketLowRes = s3.Bucket("bucket-conc-lowres")

def lambda_handler(event, context):
    # TODO implement

    mp4OutputFileName = 'output.mp4'

    new_file_key = os.path.abspath(os.path.join(os.sep, 'tmp', mp4OutputFileName))
    subprocess.call( ['/opt/ffmpeg', '-i', 'concat:s3://bucket-word-clips/00th76kqwfs915hbixycb77y9v3riwsj30.mp4|s3://bucket-word-clips/00uoakp6jyafbu13ycvl6w2i9tj42eux30.mp4', new_file_key ] )

    s3.Object(bucketLowRes, mp4OutputFileName).put(Body=open(new_file_key, 'rb'))

    return {
        'statusCode': 200,
        'body': json.dumps('Hello from Lambda!')
    }


  



  Question :

  



  

  • FileNotFoundError : Where is the output mp4 file of my ffmpeg concat being saved ??

  


  • And if it is being saved to /tmp/output.mp4 , then why the FileNotFoundError ??

  


  



  thanks
