• Why can't we find the header file that actually exists ?

  15 décembre 2020, par zhukov18961201

  I am a C language beginners, I encountered a problem, can not find the header file, but in fact, these header files are in the current file, I saw online methods (for example : solution) are to add - I option can solve this problem, but I am very curious, why can't it find itself, can only rely on - I option ?

}


  


  compile :

• No such file or directory : 'ffmpeg' in Django/Docker

  6 avril 2024, par tthheemmaannii

  I run my Django code in Docker. I run transcription software that requires ffmpeg to function. However I've been getting the error [Errno 2] No such file or directory: 'ffmpeg' whenever I try to run my code.

  


  Here's my views.py :

  


  def initiate_transcription(request, session_id):
    ...
                with open(file_path, 'rb') as f:
                    path_string = f.name
                    transcript = transcribe_file(path_string,audio_language, output_file_type)

   ...


  


  Here's my Dockerfile :

• Parsing the STDERR output of node.js child_process line by line

  3 janvier 2012, par primer

  I'm writing a simple online conversion tool using FFMPEG and Node.js. I'm trying to figure out how to parse each line of the conversion output received from FFMPEG and only display pertinent results client side in the browser. In my case I want the encoding time counter that FFMPEG spits out on the command line.

  My function thus far is :

  function metric(ffmpeg, res) { 
  
  
  
    ffmpeg.stdout.on('data', function(data) {
  
       res.writeHead(200, {'content-type': 'text/html'});
  
       res.write('received upload:\n\n');
  
       console.log(data);
  
    });
  
  
  
    ffmpeg.stderr.on('data', function (data) {
  
       var temp += data.toString();
  
              var lines = temp.split('\n');
  
  
  
              //for debugging purposes
  
              for(var i = 0;icode>

  What this ends up returning is multiple arrays, each of which includes the data from the previous array as well as the next data chunk. For example, the function returns array 1 :0=>A, 1=>B, array 2 :0=>A, 1=>B, 2=>C, array 3 :0=>A, 1=>B, 2=>C, 3=>D, and so on.

  I'm quite new to Node so I'm probably missing something simple. Any guidance would be much appreciated !
