• How to download m3u8 playlist with URL redirection ? (blob URL,HydraX, JW Player version 8.4.2)

  17 novembre 2019, par wltprgm

  The video in https://hydrax.net/ is using HLS, .m3u8 file, direct link is https://hydrax.net/demo/hydrax.html (from the iframe src).

  However, youtube-dl couldn’t read from the .m3u8 file I downloaded from blob in chrome.

  And using ffmpeg method (which usually works) to download from the .m3u8 file failed because the first segment of the file is a URL redirect

  Error when loading first segment 'https://i.donald-gaines.xyz/redirect/7qC173pnWiDwe2TumUTYnzX4WdbPn8XJDzhqDzXPo39PWtX4EaAxLq7FLUW17aI/WhsiWh1RO6oSXzr6QqkTOgljgRrXBgpJtQf6gMBAC5Jq95JkuQlWKpfpgPoo/BSGGloj6MOe7cO4K9HoDj76PRzjSVoiwcJ1Xl34kc3Z5/Bl2WS3KO8WsicRVG8l1EBoi3RN2DnqZx6o13U56YnDBv'

• 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.

• Change youtube-dl download output (Windows)

  24 octobre 2019, par Inforcer25

  I hope you can help me.

  I am using youtube-dl on windows (youtube-dl.exe)
  Downloading the video works great and also just the audio. But what i want is for it to save the audio file in a different place eg. C :\Users*******\Desktop

  I made a batch file with this code :

  :audio
  
  cls
  
  echo.
  
  echo.
  
  echo Your audio vill be downloaded and saved as a .mp3 format
  
  echo.
  
  echo.
  
  set /p audio=Enter Video URL here:
  
  cls
  
  youtube-dl.exe --extract-audio --audio-format mp3 --output C:\Users\*******\Desktop\(ext)s.%(ext)s %audio%
  
  pause
  
  cls
  
  echo.
  
  echo.
  
  echo.
  
  echo.
  
  echo Your audio has now been downloaded.
  
  ping localhost -n 3 >nul
  
  exit

  and then it gives me this

  Usage: youtube-dl.exe [OPTIONS] URL [URL...]
  
  
  
  youtube-dl.exe: error: You must provide at least one URL.
  
  Type youtube-dl --help to see a list of all options.
  
  Press any key to continue . . .

  It works fine if i use this but it saves it in the same folder.

  :audio
  
  cls
  
  echo.
  
  echo.
  
  echo Your audio vill be downloaded and saved as a .mp3 format
  
  echo.
  
  echo.
  
  set /p audio=Enter Video URL here:
  
  cls
  
  youtube-dl.exe --extract-audio --audio-format mp3 %audio%
  
  pause
  
  cls
  
  echo.
  
  echo.
  
  echo.
  
  echo.
  
  echo Your audio has now been downloaded.
  
  ping localhost -n 3 >nul
  
  exit

  Also please keep in mind that it also uses ffprobe.exe and ffmpeg.exe (They are both in the same folder as youtube-dl.exe
