• Differentiate between error and standard terminal log with ffmpeg - nodejs

  9 avril 2017, par Guig

  I’m using ffmpeg in node js. Both the standard terminal output and the error seems to be sent to stdout, so I don’t know how to differentiate between error and success... Here’s my code :

  var convertToMp3 = function(filePath) {
  
    var ffmpeg = child_process.spawn('ffmpeg',['-i', filePath, '-y', 'output.mp3']);
  
    var err = '';
  
    ffmpeg.stderr
  
      .on('data', function(c) { err += c; })
  
      .on('end', function() { console.log('stderr:', err); });
  
    var d = '';
  
    ffmpeg.stdout
  
      .on('data', function(c){d +=c;})
  
      .on('end', function(){ console.log('stdout', d); });
  
  }

  wether the conversion succeeds or fails, stdout is empty and stderr contains what I’d get if I’d run the corresponding command in the terminal

• Include an executables into UWP final package

  11 janvier 2019, par kangjmoon

  I’m writing an UWP Store app that calls other executables, such as OpenSSL and FFmpeg.exe. I successfully included those in a WPF app. However, with UWP, how to build them into the final package to upload to the Windows Store ?

  I’m thinking of these solutions :

  1. Add the needed file (for example, FFmpeg.exe) to the project. Then chose the Build Action property to ’Content’ and copy to Output Directory. But this option seems not possible with the whole folder with sub-folders and files in them (for example, OpenSSL portable folder).

  2. Write a method to copy the file (FFmpeg.exe) into the Local Folder of UWP app when the program starts.
     ...

  Is there a better way to do this ? Thanks.
