• 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.

• download compressed video from m3u8 link

  6 juin 2020, par alsaibi

  i'm making a python script to download videos from a site

  



  it's working perfectly but some videos are m3u8

  



  the links are something like this

  



  https:\/\/dl.v.vrv.co\/evs\/5e915ac2127515861ea2563ca4e3eb25\/assets\/jpy1j4wghs4eepk_,1605371.mp4,1605379.mp4,1605363.mp4,1605355.mp4,1605347.mp4,.urlset\/master.m3u8?Policy=eyJTdGF0ZW1lbnQiOlt7IlJlc291cmNlIjoiaHR0cCo6Ly9kbC52LnZydi5jby9ldnMvNWU5MTVhYzIxMjc1MTU4NjFlYTI1NjNjYTRlM2ViMjUvYXNzZXRzL2pweTFqNHdnaHM0ZWVwa18sMTYwNTM3MS5tcDQsMTYwNTM3OS5tcDQsMTYwNTM2My5tcDQsMTYwNTM1NS5tcDQsMTYwNTM0Ny5tcDQsLnVybHNldC9tYXN0ZXIubTN1OCIsIkNvbmRpdGlvbiI6eyJEYXRlTGVzc1RoYW4iOnsiQVdTOkVwb2NoVGltZSI6MTU5MTU1ODg4Nn19fV19&Signature=S7bDaUsOAplp437a-2hBIiED-jgwGCHups-cCHFK0etbVwn5O0Lx09~yiPvOnL9kae3AHFbPnlduxwotDDzKUMy01Swbudjz~HLwR26Lp1fb1vKAhZDgM1LJPkBFuQSbCYfN4cKG2aihTfbxNy3S63sUdQJouVjxwgkIj069kIjTmj7GsMfFgqrvYZja~RUOvF7n4evA0iisKbzTio4gB3gGYBhqOe~rh1rSbqGsO92U1AiflVGETpgo~z0p89agQGK4LHamKEWQUF2vITqYA2WXKYV1qNNg5JJ3ZDJUp3L3qE2zCBige1qw9UYtxr7jvg-PhZh4Esr07xS5G7UfQA__&Key-Pair-Id=DLVR


  



  i'm trying to download mp4 or mkv file to watch the video offline

  



  i tried using ffmpeg and youtube-dl

  



  they only work after changing \/ in the link to //

  



  ffmpeg command i used ffmpeg -i "Link" -bsf:a aac_adtstoasc -vcodec copy -c copy -crf 50 file.mp4

  



  that's not the problem

  



  they download the full raw video file which is around 1.5GB

  



  but in the site watching the video take maximum 250MB at highest quality

  



  and the download is really slow for some reason

  



  it take almost 1 hour to download 1 video

  



  and at the end video don't open after finish downloading

  



  vlc say it's corrupted

  



  isn't there is a way to convert the link to direct link to compressed file link ?

  



  the site take 200MB to watch the video and loading the video is fast but downloading it from the link above take 1.5GB and it's soo slow

  


• Anomalie #4598 (Fermé) : PHP 8 : Resource vs GdImage object problem.

  4 novembre 2020

  GD ne retourne plus une "resource", mais une instance de GdImage.

  Ça fait planter une partie des filtres images dans SPIP.
  Notamment s’il y a des tests avec is_resource()

  Exemple :
  

  Warning : Trying to access array offset on value of type bool in [...]ecrire/inc/filtres_images_lib_mini.php on line 1607 à 1610
  Qui provient de grosso modo :
  
  [(#CHEMINun_fichier.png|image_applatirico)]
  

  Docs¶

  - https://php.watch/versions/8.0/gdimage
  - La correction chez WP : https://core.trac.wordpress.org/ticket/50833

  Avec la solution proposée :

  Note that in PHP 7.2 and older, instanceOf operator requires an object. If you need to make your code function across PHP versions older than 7.3 through PHP 8.0, you will need an additional is_object() check :

  - if (is_resource($image))
  + if (is_resource($image) || (is_object($image) && $image instanceOf \GdImage))
