• Access files in a directory and write the file paths to a text file in ascending order using PHP

  26 mars 2014, par SCC

  I have a list of video files in my server. I would like to list out all the video files in this directory and write it to a text file. These video files are all having the same name output-x.mp4, and x is the number from 0 to an unknown figure. The total number of video files is dynamic and therefore I don't get to know the number of the last video. I have the below code to access all the video files in this directory. It works fine with only one problem : The video files written to the text file are not sorted in ascending order.

  $directory = "video/myvideo";
  
  $fp = fopen($_SERVER['DOCUMENT_ROOT']."Path/to/text/file", "wb");
  
  $split_video_files = scandir($directory);
  
  foreach($split_video_files as $file)
  
  {
  
      $content = "file ".$directory.$file."\r\n";
  
      fwrite($fp, $content);
  
  }
  
  fclose($fp);

  What the text file gave me is this :

  video/myvideo/output-0.mp4
  
  video/myvideo/output-1.mp4
  
  video/myvideo/output-10.mp4
  
  video/myvideo/output-11.mp4
  
  video/myvideo/output-12.mp4
  
  video/myvideo/output-13.mp4
  
  video/myvideo/output-14.mp4
  
  video/myvideo/output-2.mp4
  
  video/myvideo/output-3.mp4
  
  video/myvideo/output-4.mp4
  
  video/myvideo/output-5.mp4
  
  video/myvideo/output-6.mp4
  
  video/myvideo/output-7.mp4
  
  video/myvideo/output-8.mp4
  
  video/myvideo/output-9.mp4

  It lists out all the filename that start with "1" first before proceed to "2" and so on. Any ways for me to sort it in ascending order so that it starts from 0, 1, 2,… ?

• check if file is downloaded in temp in GCF from GCS

  3 septembre 2020, par soshi

  Im making video encoder using GCF

  


  that downloads video file from gcs to /tmp and encode it by ffmpeg.

  


  I want to ask how to check if file is downloaded in tmp ?

  


  I tried console.log(process.cwd()) but tmp folder is not displayed

  


  exports.encodeVideo = async (req, res) => {

 mkdirp('/tmp')

 storage.bucket('video-bucket').file('raw/samplevideo.mp4').download({ 
 destination:'encoded/samplevideo.mp4' })

ffmpeg........
}


  


• How can I take a user input in python3 and use it for the file name of ffmpeg-python file output ?

  25 novembre 2022, par tylerdurden4285

  I am trying to do something like this :

  


  import ffmpeg

user_input =input("give your output file a name: ")

(
    ffmpeg
    .input('input.mp4')
    .vflip()
    .output('(user_input).mp4')
    .run()
)



  


  I am wondering how I can take the string input from the user and make it the filename. So if they input "tester" the resulting output file would be "tester.mp4".

  


  I am running it on an ubuntu 20.04 WSL. I'm new to here and doing my best to learn python3 and ffmpeg so please be gentle with me if I broke any community rules. I'll improve as I go.

  


  I don't know what to search for to find the answer to this problem.
