• My server is constantly downloading a file, and I don't know what it is [closed]

  7 novembre 2023, par fatemeh mojarrad

  I am converting video with ffmpeg and every few hours my server downloads a file and I don't know what it is and I want to be able to identify what file the server is downloading or what package it is updating.
my requirements :
uwsgi
PyMySQL
Flask
metadata_parser
captcha
flask-compress
wget
moviepy
python-dateutil
jdatetime
flask-cors
eyed3
termcolor
tqdm
redis
zeep
nsfw-detector
Pillow
opencv-python==4.6.0.66
tensorflow==2.9.1
opennsfw2
psutil

  


  My server is Linux and my operating system is CentOS 7

  


  I searched and updated the programs, but this happened again

  


• Returned non-zero exit status 1 / error code 1 : b''

  26 août 2015, par pufAmuf

  I’m trying to extract the video height via ffprobe into python, however I am having issues (with some videos).

  Here is my ffprobe command : ffprobe -v quiet -print_format compact=print_section=0:nokey=1:escape=csv -show_entries stream=height "some video here(bla)_25.mp4"

  It returns something like this

  720
  
  (empty-line)
  
  N/A

  Here is the code I used to extract the output for later processing :

  executecommand = 'ffprobe -v quiet -print_format compact=print_section=0:nokey=1:escape=csv -show_entries stream=height "' + CurrentVideoToBeProcessed + '"'
  
  
  
  VideoHeight = subprocess.check_output(executecommand)

  This is the error that came about :

  subprocess.CalledProcessError : Command ’...’ returned non-zero exit
  status 1

  So when I modified the code to this :

  try:
  
      VideoHeight = subprocess.check_output(executecommand,shell=True,stderr=subprocess.STDOUT)
  
  except subprocess.CalledProcessError as e:
  
      raise RuntimeError("command '{}' return with error (code {}): {}".format(e.cmd, e.returncode, e.output))

  This is the error I get :

  RuntimeError : command ’...’ return with error (code 1) : b’’

  I assumed at first the issue was with the file names, but certain videos work and certain don’t, irregardless of the file name.
  This is the output I get in python for videos that work :

  b’360\r\n\r\n’

  Any idea what’s going on ? Thanks !

  Edit
  It turns out the problem is in the file names after all. From what I gather so far at least, numbers in file-names seem to be causing the error.
  Edit2
  I re-ran the code after I closed several cmd instances and I am not getting the error anymore. I don’t know why. I am sure, however that if I were to convert hundreds of videos again I’ll get the error eventually as it has always happened eventually.

• node-fluent-ffmpeg Multiple images to video

  16 août 2015, par tsurantino

  I am trying to stitch multiple .PNG images to a single .MP4 video using Node. I am using ffmpeg and specifically, the node-fluent-ffmpeg library.

  I can only get one frame to show up at a time, when I instead intend to show 100+.

  var video = ffmpeg();
  
  
  
    for (var i = 1; i <= 168; i++) {
  
      //console.log('Adding: ' + path.join(__dirname, 'public', 'tmp', 'frame-' + i.toString() + '.png'));
  
      video.input(path.join(__dirname, 'public', 'tmp', 'frame-' + i.toString() + '.png')).loop(1);
  
    }
  
  
  
    video.save(path.join(__dirname, 'public', 'videos', 'test.mp4'))
  
    .on('end', function() {
  
      console.log('file has been converted succesfully');
  
      res.redirect('/');
  
    })
  
    .on('error', function(err) {
  
      console.log('an error happened: ' + err.message);
  
    })
