• How to download audio and video as separate files and specify the output format and filename for each ?

  14 novembre 2023, par Taako

  I'd like to download a video as separate files for both audio and video and have them named [video_id]-audio.wav and [video_id]-video.mp4

  


  How do i get yt-dlp to download the video and audio separately, then convert each to the specified output format and rename them as such ?

  


  Right now I can get them each downloaded separately but the naming isnt working out.

  


  I could also use ffmpeg separately to convert the video and audio formats after they are downloaded, so all i really need is to have the audio and video files downloaded and named

  


  Right now my args are

  


  YT_OPTIONS = {
    'format': 'bestvideo[height<=720]+bestaudio/best[height<=720]',
    'extractaudio': True,
    'keepvideo': True,
    'outtmpl': '%(id)s-%(format)s.%(ext)s',
    'restrictfilenames': True,
    'noplaylist': True
}


  


  but the format is just coming out as 247_-_1280x720_720p_+251_-_audio_only_medium and whats worse is it is the same for both the audio only and video only files just one has 251 and the other has 247.

  


• Download youtube video as stream Readable object

  in this function it download youtube video as a file out.mp4 on hard disk i need to download it as a Readable Object to upload it

  


  private async downloadVideo(videoId: string) {
// Buildin with nodejs

  process.stdout.write(`Audio  | ${(tracker.audio.downloaded / tracker.audio.total * 100).toFixed(2)}% processed `);
