• Node.js ffmetadata incorrect codec parameters

  21 juillet 2015, par Ahmed Hamdy

  I’m making a song downloader app in Node.js. I managed to get everything to work, the app downloads the song and downloads its artwork (image). So I have the mp3 file and jpg file. The only problem is attaching the jpg file to the mp3 file.

  I’m using the ffmetadata node.js module. I downloaded and installed its dependency "ffmpeg" cli.

  Now when I try to write the metadata to the mp3 file and attach the artwork it spits this error :

  Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

  My code :

  ffmetadata.write('test.mp3', {}, {attachments: ['test.jpg']}, function(err) {
  
    if (err) console.error(err);
  
  });

  The error :

• Transcoding video using ffmpeg from the internet or over http

  19 juillet 2015, par Robin

  I have a project for transcoding videos. Right now I am passing the absolute path of the video as the input variable, as such :

  inputfile = str(MEDIA_ROOT)+'/'+str(video.original_video)

  Here the MEDIA_ROOT is /home/user/code/Project/Viu/static/media

  And then

  subprocess.call(
  
          'ffmpeg -i '+ inputfile +' -codec:v libx264 -crf 23 -preset faster -codec:a libfdk_aac -vbr 4 \-movflags faststart -vf scale="720:trunc(ow/a/2)*2",format=yuv420p '+ outputfile,
  
          shell=True
  
      )

  This is ok for now. But I will be keeping those videos on different location from the server, how can I convert videos from that location over the internet or http?

  I tried this :

  inputfile = 'http://localhost:8000/media/'+str(video.original_video)

  But I get this error :

  [2015-07-19 13:27:14,933: INFO/MainProcess] Received task: vids.tasks.convert_video[41e36bc6-0d6a-4756-99fb-cb8005a4fbe3]
