• Download a youtube video without storing it on the server

  6 mai 2019, par Baraque Obahamas

  I have a personal php script that allows me to download the videos of my choice. Currently, this runs youtube-dl and if necessary convert the video, ffmpeg then.

  I’m looking for a way to allow my script to download/convert the video without even storing it on the server. Make sure that youtube-dl/ffmpeg acts as a gateway but without downloading the file.

  Do you have any idea how to do this ? The idea would be to run ffmpeg on the youtube link and not on the video after it has been downloaded, and allow the user to download it at the same time as the conversion is in progress.

  We can see that this site for example www.onlinevideoconverter.com uses this method, because if we ask for a video of 2 hours or more, it allows us to download it immediately.

• Batch Script to Download Video with youtube-dl and Convert with FFmpeg

  24 octobre 2019, par Matt McManis

  I’m trying to

  1. Using a single batch script to
  2. Download an mp4 video using youtube-dl
  3. Save the video’s original title to a batch variable
  4. Convert the video to webm with FFmpeg

  I want to keep the original title, so it needs to read the title with youtube-dl, save it to a variable, and use that variable for FFmpeg input/output filename.

  ---

  CMD Batch

  1. Download Video

  youtube-dl -f best "https://www.youtube.com/watch?v=TWNhqCHw0qc" -o "C:\Users\Matt\Downloads\%%(title)s.mp4" --merge-output-format mp4

  ---

  2. Download Video using Loop

  This is used to save the title to a variable %%a.

  for /f "delims=" %%a in ('youtube-dl -f best "https://www.youtube.com/watch?v=TWNhqCHw0qc" -o @"C:\Users\Matt\Downloads\%%(title)s.mp4" --merge-output-format mp4') do (echo example)

  ---

  3. Final Script
  Download Video, Save Title, Convert with FFmpeg

  Sorted

  for /f "delims=" %%a in ('
  
      youtube-dl 
  
      -f best "https://www.youtube.com/watch?v=TWNhqCHw0qc" 
  
      -o @"C:\Users\Matt\Downloads\%%(title)s.mp4" 
  
      --merge-output-format mp4
  
      ')
  
  
  
  do (ffmpeg -y 
  
      -i "C:\Users\Matt\Downloads\%%a.mp4" 
  
      -c:v libvpx -b:v 1300K -crf 16 -pix_fmt yuv420p 
  
      -map 0:v:0? -sn 
  
      -c:a libvorbis -q:a 6 -ac 2 -map 0:a:0? 
  
      -f webm
  
      "C:\Users\Matt\Downloads\%%a.webm"
  
      )

  Inline

  for /f "delims=" %%a in ('youtube-dl -f best "https://www.youtube.com/watch?v=TWNhqCHw0qc" -o @"C:\Users\Matt\Downloads\%%(title)s.mp4" --merge-output-format mp4') do (ffmpeg -y -i "C:\Users\Matt\Downloads\%%a.mp4" -c:v libvpx -b:v 1300K -crf 16 -pix_fmt yuv420p -map 0:v:0? -sn -c:a libvorbis -q:a 6 -ac 2 -map 0:a:0? -f webm "C:\Users\Matt\Downloads\%%a.webm")

  Error

  Before the script can ever reach FFmpeg, youtube-dl fails to download the file. It says the file has already been downloaded, even when there is no file in the directory.
