• 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 :

  


  # Pull base image
FROM python:3.11.4-slim-bullseye

# Set environment variables
ENV PIP_NO_CACHE_DIR off
ENV PIP_DISABLE_PIP_VERSION_CHECK 1

• 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 !

• Ffmpeg compression cron cutting video to 1 second

  6 août 2022, par BlackThorn

  I have a cron setup to take locally uploaded videos, create a screengrab, compress the video and upload to online storage. I am using ffmpeg with php and have tried a few different ways but though it does compress the file size I keep getting a saved file of just the first second of the video. I tried delaying the process in case it just didn't have enough time to do the video and that was the cause but it didn't seem to do much. Here are some of the examples of the code I've tried all together (commented out as tried each but you can see the different ways) :

  


  try {
    // compress video if needed
    $bitrate = "5000k";
    // $command = "ffmpeg -i ".($temp_dir."/".$folder."/".$sub_file)." -b:v $bitrate -bufsize $bitrate ".$temp_dir."/".$folder."/edit-".$sub_file;
    // $command = "ffmpeg -i $temp_video -qscale 0 ".$temp_dir."/".$folder."/edit-".$sub_file;
    $command = "ffmpeg -i ".($temp_dir."/".$folder."/".$sub_file)." -vf scale=1280:-1 -c:v libx264 -preset veryslow -crf 24 ".$temp_dir."/".$folder."/edit-".$sub_file;
    //system($command);
    $output=null;
    $retval=null;
    exec($command, $output, $retval);
    $temp_video = $temp_dir."/".$folder."/edit-".$sub_file."";
} catch (Exception $e) {
    // log output
}


  


  Is there a known issue with this or something I'm missing ?

  


  Thanks
