• Smartly concatenating gopro mp4 files - file-001.mp4 + file-002.mp4

  12 décembre 2017, par molly78

  Hello much smarter than me people out there...

  I have a folder of GoPro files which I have already renamed using this awesome utility : https://github.com/kcha/gopro_renamer

  However, I now have a folder of 110 files which should make up about 50 continuous videos...

  Some of which have only filename-001.mp4 parts, some are filename-001.mp4 and filename-002.mp4 parts. It could go on an on to say 10 parts per video, for argument sake.

  I’d like to get a hand with a script that would scan the folder and then join all the parts together into a new file.

  In windows 10 I know I can do a simple

  copy /b "C:\Filename-001.mp4" + "C:\Filename-002.mp4" Filename.mp4

  Just a bit lost how to loop thru this scenario with a (python is fine) script. I do not wish to re-encode them, simply join the parts that correspond to the base filename.

  So go from files looking like

  filename1-001.mp4 - 87 MB
  
  filename2-001.mp4 - 100 MB
  
  filename2-002.mp4 - 100 MB
  
  filename2-003.mp4 - 22 MB
  
  filename3-001.mp4 - 100 MB
  
  filename3-002.mp4 - 34 MB

  after concatenating the parts it would look like :

  filename1.mp4 - 87 MB (nothing done other than rename)
  
  filename2.mp4 - 222 MB (all joined)
  
  filename3.mp4 - 134 MB (all joined)

  Your help is greatly appreciated.

• Concat audio files then call create file

  11 mai 2020, par bleepbloopbleep

  I am new and am trying to concat a folder of audio files and then stream the create file with ffmpeg in node.js.

  



  I thought I could call the function that creates the file with await and then when it's done the code would continue allowing me to call the created file. However thats not whats happening. I am getting a "file undefined"

  



  Main function

  



  //CONCATS THE FILES
  await concatAudio(supportedFileTypes.supportedAudioTypes, `${path}${config[typeKey].audio_directory}`);

  // CALLS THE FILE CREATED FROM concatAudio
  const randomSong = await getRandomFileWithExtensionFromPath(
    supportedFileTypes.supportedAudioTypes,
    `${path}${config[typeKey].audio_final}`
  );


  



  concatAudio function

  



  var audioconcat = require('audioconcat');
const getRandomFileWithExtensionFromPath = require('./randomFile');
const find = require('find');

// Async Function to get a random file from a path
module.exports = async (extensions, path) => {
  // Find al of our files with the extensions
  let allFiles = [];

  extensions.forEach(extension => {
    allFiles = [...allFiles, ...find.fileSync(extension, path)];
  });

  await audioconcat(allFiles)
    .concat('./live-stream-radio/final/all.mp3')
    .on('start', function(command) {
      console.log('ffmpeg process started:', command);
    })
    .on('error', function(err, stdout, stderr) {
      console.error('Error:', err);
      console.error('ffmpeg stderr:', stderr);
    })
    .on('end', function(output) {
      console.error('Audio created in:', output);
    });

  // Return a random file

  // return '/Users/Semmes/Downloads/live-stream-radio-ffmpeg-builds/live-stream-radio/final/all.mp3';
};


  


• How to avoid downloading the same video with different file extension (remux) in yt-dlp

  23 décembre 2022, par Daniel

  This is the command I'm using to download my videos :
yt-dlp —remux "webm>avi" -o "%(upload_date)s %(title)s.%(ext)s" -f bv[format !*=248] -a List.txt

  


  I have text files with tons of links
So, if the videos are already downloaded in avi format
yt-dlp doesn't detect it, instead it downloads the video again creating a webm.part file, then it remuxes the file and overwrites the old avi downloaded video

  


  I know the cause of this is the ".%(ext)s" command but I cannot remove that part

  


  So what I need is for yt-dlp to recognize the file name instead of the extension, because from time to time I will need to check those video lists again with yt-dlp, to check for missing videos, or if I add new link videos to those lists
