• Edit audio files on the server with Meteor

  28 décembre 2015, par Mohammed Hussein

  I am building a Meteor application to split uploaded audio files.

  I upload the audio files and store them using GridFS :

  child = Npm.require('child_process');
  
  
  
  var fs = Npm.require('fs');
  
  
  
  storagePath= fs.realpathSync(process.env.PWD+'/audio');
  
  
  
  StaticServer.add('/audio', clipsPath);

  and then using a method I split the audio file using :

  child.exec(command);

  the command is the ffmpeg command used to cut the source audio file and store it on the storagePath.

  The application worked fine locally but when I tried to deploy it to digital ocean I got errors, stating that the file /audio does not exist.
  I use mupx to deploy and the error appears after "verifying deployment".

  Here is the error :

  The main question is how to generate an output file using ffmpeg and store it in a place where I can access it and display it in the browser.

  doc/examples/muxing : Remove outdated comment
  This comment only applies to the scenario in which one uses
  
  the AVCodecContexts embedded in AVStreams. Yet this code sample
  
  stopped doing so in 9897d9f4e074cdc6c7f2409885ddefe300f18dc7 ;
  
  and the last major version bump even removed the public
  
  AVCodecContexts in AVStreams. So just remove this comment.

• pixfmt : remove misleading and broken documentation

  pixfmt : remove misleading and broken documentation
  This was probably broken some time ago. The breakage is now part of the
  
  ABI. For example, we have :
      AV_PIX_FMT_XYZ12BE
  
      AV_PIX_FMT_NV16
  
      AV_PIX_FMT_NV20LE
  AV_PIX_FMT_NV20LE is wrong. It has the value 113, but as little-endian
  
  format it should be even. This must have been quite obvious when these
  
  formats were added (because of the AV_PIX_FMT_XYZ12BE entry), but
  
  nobody cared or knew about this.
  The future libavutil major bump will also break this additionally,
  
  because disabling FF_API_VDPAU will remove an odd number of entries from
  
  the middle of the enum.
