• 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

  


• 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] @C#\Users\Matt\Downloads\Color Balloons.mp4 has already
  been downloaded

• FFMPEG Crop with side by side merge

  14 février 2016, par Alan

  I am trying to create a shell/ffmpeg script that can show multiple files after they have been processed using different filters in a side by side / tiled way. An example of desired output would be : https://www.youtube.com/watch?v=DoPuhMRYem4.

  In order to create the desired output I need to crop off the right half of video1 and the left half of video2 and then join them back with [video1+video2] side by side. I have played around with a bunch of different ways of joining them, this does OK :

  ffmpeg -i input1.mp4 -i input2.mp4 -filter_complex "
  
  nullsrc=size=800x400 [background];
  
  [0:v] setpts=PTS-STARTPTS, scale=400x400 [left];
  
  [1:v] setpts=PTS-STARTPTS, scale=400x400 [right];
  
  [background][left]       overlay=shortest=1       [background+left];
  
  [background+left][right] overlay=shortest=1:x=400 [left+right]
  
  " -map '[left+right]' joined.mp4

  How can I modify this to detect the video width (they won’t always be the same width), divide the width in half and crop either the left or right sides off ?
