• Do ffmpeg create thumbnail download all of file via URL nodejs ?

  11 novembre 2019, par Nam Nguyễn

  I am creating a thumbnail from video URL by ffmpeg.

  This is my code :

  function createThumbnail(videoURL, keyFileThumb) {
  
      return new Promise((resolve, reject) => {
  
          let tmpFile = createWriteStream(`./${keyFileThumb}`)
  
          const ffmpeg = spawn(ffmpegPath, [
  
              '-ss',
  
              '00:00:01.000',
  
              '-i',
  
              videoURL,
  
              '-frames:v',
  
              '1',
  
              '-f',
  
              'image2',
  
              '-c:v',
  
              'mjpeg',
  
              'pipe:1'
  
          ])
  
  
  
          ffmpeg.stdout.pipe(tmpFile)
  
  
  
          ffmpeg.on('close', function (code) {
  
              tmpFile.end()
  
              resolve(code)
  
          })
  
  
  
          ffmpeg.on('error', function (err) {
  
              console.log(err)
  
              reject(err)
  
          })
  
      })
  
  }

  I just want to create thumbnail from stream video URL then disconnect. I do not want download all of file to generate thumbnail in few second of video.

• How Can i Download this video ? Encrypted m3u8 ?

  16 septembre 2022, par אורן NO

  Hello everyone For almost a whole month now I have been trying to download a file from a specific site

  


  This is the link to the video
https://www.karaoke.co.il/api_play.php?type=clip&id=58370&autoplay=undefined&referer=karaoketv

  


  The M3u8 files are split into 2 parts.

  


  Video file
https://www.video-cdn.com/video/encrypt/750802ea0bc2d02fac93adeaa1398ec2/750802ea0bc2d...2-57d9518fae69

  


  And an audio file
https://www.video-cdn.com/video/encrypt/750802ea0bc2d02fac93adeaa1398ec2/750802ea0bc2d...2-57d9518fae69

  


  As far as I know there is a Key that needs to be entered in order to download the file.

  


  And when I run the command in ffmpeg

  


  I encounter many errors like :
Unable to open key file

  


  Anyone who can download it.
I would be very happy if he would write me a code that works and explain to me how to do it

  


  These are all the codes I have already tried

  


  ffmpeg -decryption_key https://www.video-cdn.com/video/key/750802ea0bc2d02fac93adeaa13cde64 -i https://www.video-cdn.com/video/encrypt/750802ea0bc2d02fac93adeaa1398ec2/750802ea0bc2d02fac93adeaa1398ec2/video_720p.m3u8?token=R915dD-72351a7c-3dd1-4e58-b6c2-9cc813eeb183 -vcodec libx264 {output_file}


  


  ffmpeg -decryption_key key -i file -max_muxing_queue_size 9999 d.mp4
