Youtube-DL Download DashStream

less than 1 minute read


If you want to download a stream .m4s but cannot seem to find the mpd file, use this combination.

To Resolve:

1a. Download ‘The Stream Detector’ addon (I use Firefox, not sure if available in Chrome) and the youtube-dl executable.

  1. Run:
.\youtube-dl.exe "URL from the Stream detector" -o c:\scripts\myfile.mp4 -c

-o is the file you choose
-c keeps the connection alive
NOTE: If you run into any issues, just run the same command again and it will pick up where it left off

After downloading videos, I often have to shrink them. You can do this with ‘handbrake-cli’.

Shrink MP4 Files:

  1. Open the application and right click “Fast 1080p 30” and choose – Export json

  2. Run:

c:\scripts\HandBrakeCLI.exe --preset-import-gui "c:\scripts\preset.json" -i "c:\scripts\aquaman.mp4" -o "c:\scripts\aquaman2.mp4"
  1. If you want handbrake to run in batch mode, just pass it a bunch of paths and have it convert them one by one:
$files = @(

foreach ($file in $files)
Write-Output "Converting file: $file"
$file2 = $file.replace(".mp4", "-enhanced.mp4")
& C:\scripts\HandBrakeCLI.exe --preset-import-gui "c:\scripts\preset.json" -i $file -o $file2
Write-Output "Removing original file: $file"
Remove-Item $file -Force
Write-Output "Writing file: $file2"
