• Fluent-ffmpeg "not a suitable output format"

  5 septembre 2015, par J4G

  I’m using the fluent-ffmpeg module for Node.js to convert audio files. I have a .mp3 file that I’d like to convert to .wma

  Here’s what that looks like :

  var proc = new ffmpeg({
  
     source: 'file.mp3',
  
     nolog: false
  
  }).toFormat('wma')                                                
  
    .saveToFile('file.wma', function(stdout, stderr)
  
  {                                                 
  
      console.log(stderr);
  
  });

  Unfortunately, I get the error :

  Requested output format 'wma' is not a suitable output format

  This is the entire error log :

  ffmpeg version 0.8.9-4:0.8.9-0ubuntu0.12.04.1, Copyright (c) 2000-2013 the Libav developers

  Requested output format 'wma' is not a suitable output format

  I know this isn’t an ffmpeg issue because

  ffmpeg -i file.mp3 file.wma

  Works fine. Any ideas ?

• node js (or other) as streaming server

  20 décembre 2013, par Abdul Ali

  Apologies if a simple question but cannot find anything helpful . Am also new to the streaming concept.

  Goal is to set up a server which keeps on listening for data on a speific port. The user will be sending sequence of images from their iphone (# of images unknown).

  when the data is receieved, ffmpeg should start to get data from that port (as input) and send those images to ffserver to be streamed as a live video.

  did try Nginx-Rtmp module but the iphone developer have informed that in iphone, only ip and port can be given to open a stream (and no other part of the url can be given e.g. streamname and application name in case of nginx-rtmp)

  Any help and guide will be appreciatd that what can be used to set up a free and very simple sever that simply receives the images which ffmpeg can capture and send to ffserver .

• Can I use AForge in Unity3D ?

  19 décembre 2013, par user2967920

  I am Using Unity Pro,

  i want to Decode and play H264 Encoded Content in Unity3D. As unity dosn't have native support for the h264 codec so i got AForge.NET.

  In visual Studio 2010 i created an application which would do the decoding and give the output as a bitmap to a rectangle which was drwn using SDL, so i know the .net AFOrge works well.

  Now the Problem is when i import the AForge.dll, AForge.Video and the AForge.Video.FFMPEG in Unity i git this Error.

  "MissingMethodException : Method contains unsupported native code

   <module>.<crtimplementationdetails>.LanguageSupport._Initialize (<crtimplementationdetails>.LanguageSupport* )
  
      <module>.<crtimplementationdetails>.LanguageSupport.Initialize (<crtimplementationdetails>.LanguageSupport* )
  
      Rethrow as ModuleLoadException: The C++ module failed to load.

  </module></module></crtimplementationdetails></crtimplementationdetails></module></crtimplementationdetails></module></crtimplementationdetails></crtimplementationdetails></module></crtimplementationdetails></crtimplementationdetails></module>

  Aforge (Core), Aforge.Video and Aforge.Video.FFMPEG are compiled using Target Framework (3.5).

  The AForge.Video.FFMPEG has a Reference to kernel32.dll, MSVCR100.dll which is not exactly showing in monoDevelop. the rest are expanding and i can browse their contents in the Assembly Browser.

  Is there any way to get AForge working in monodevelop ? the ffmpeg wrapper is written in C++. I mean make it not use those references ?

  If Anyone has worked on such a thing before, it would be of great help thanks.
