• Use bash script with yt-download and ffmpeg to extract OR covert depending on format

  7 juin 2018, par Keyslinger

  I have a batch of files I uploaded to YouTube which I now wish to backup on my MacBook. When I download and extract the audio, I get either *.m4a or *. opus :

  #!/bin/sh
  
  ID="$1"
  
  
  
  youtube-dl -f bestaudio -x -i --audio-format best -o '%(playlist)s/%(playlist_index)s %(uploader)s - %(title)s.%(ext)s' https://www.youtube.com/playlist?list="$ID"

  When the file extension is m4a, I need to leave it that way and perform no conversion, when the extension is opus, I need to convert it to m4a.

  If I want to convert every file, I can do something like this :

  youtube-dl -f bestaudio -x -i --audio-format m4a -o '%(playlist)s/%(playlist_index)s %(uploader)s - %(title)s.%(ext)s' https://www.youtube.com/playlist?list="$ID"

  But then the conversion is performed no matter what.

  How can I extract and only convert when the file extension is not m4a ?

• How to download video streaming powered by JW Player 8.4.2 + iframe src from hydrax.net combined ? [on hold]

  20 octobre 2019, par Tév

  I find that downloading a video that streamed via JW Player 8.4.2. which using hydrax.net as the media source is really annoying & frustrating because I’ve done my best with the all solution I’ve found comes to nothing.

  Is there any solution left I can try ?

  I’m trying to download video from http://javmile.com/dvd/anna-marie-patsukin-channel-z-vol/39585 with ffmpeg & youtube-dl but not worked.

  I tried to stream/convert the .m3u8 file I managed to download with VLC but still not worked.

  I also tried to look for the alternative from Inspect -> Network -> Media and all that I got is a blob link that ends dead end. Inspect -> Application also doesn’t provide any solution since there’s no Video frame.

  Last but not least, I’ve tried the Video DownloadHelper extension from Firefox trick to download the video from the referrer/url link but it’s failed too.

  The referrer link I’ve got from the Video DownloadHelper Firefox’s extension :

  The url link I’ve got from the Video DownloadHelper Firefox’s extension :

  The blob link that’ll lead me to the .m3u8 file download :

  blob :https://hydrax.net/e9166d00-1aba-4832-b7bf-8cb011abcc10

  And here the .m3u8 file content I’ve managed to download :

  EXTM3U
  EXT-X-VERSION:3
  EXT-X-STREAM-INF:BANDWIDTH=394000,RESOLUTION=480x360

  Command that I used to download the video with the ffmpeg :

  ffmpeg -i [neither of referrer/url link from DownloadHelper nor blob link from the .m3u8 file content worked] -vcodec copy -acodec copy MyOutput.mp4

  ---

  Command that I used to download the video with the youtube-dl :

  youtube-dl -i [neither of referrer/url link from DownloadHelper nor blob link from the .m3u8 file content worked] -vcodec copy -acodec copy MyOutput.mp4
