• 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

  


• 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';
};


  


• Parsing file-like object into create_ffmpeg_player in discord.py not working

  3 août 2018, par user4757174

  The API documentation for create_ffmpeg_player says it allows passing file-like objects into create_ffmpeg_player as it will be passed to stdin.

  create_ffmpeg_player(filename, *, use_avconv=False, pipe=False, stderr=None, options=None, before_options=None, headers=None, after=None)

  filename – The filename that ffmpeg will take and convert to PCM bytes. If pipe is True then this is a file-like object that is passed to the stdin of ffmpeg

  here’s what I am inputting :

  buffer = BytesIO()
  
  c.setopt(c.WRITEDATA, buffer)
  
  c.perform()
  
  player = voice.create_ffmpeg_player(buffer,pipe=True)

  The PycURL object writes data to buffer which is the BytesIO object.

  Then I try to parse the file-like object into create_ffmpeg_player() but I get the following error :

      Traceback (most recent call last):
  
    File "C:\Users\user\AppData\Local\Programs\Python\Python36\lib\site-packages\discord\client.py", line 307, in _run_event
  
      yield from getattr(self, event)(*args, **kwargs)
  
    File "test.py", line 116, in on_message

      p2cread = msvcrt.get_osfhandle(stdin.fileno())
  
  io.UnsupportedOperation: fileno

  The error shows me that somewhere in the stack, a routine is trying to get the fileno() of the object, but since this is not a real file, there is no file handle, or "fileno". For a temporary work-around I am creating a physical file on disk and parsing that file into the function, but for this program, the function will be run many times so doing physical read/writes is not practical. Is it possible to work around this, or at least create a file on memory with the ability to get/spoof a fileno ?
