• Creating a PowerShell Streamer Function w/youtube-dl, ffmpeg & ffplay

  11 juillet 2017, par Adam Chilcott

  My question is in regards to combining youtube-dl, ffmpeg, ffplay and PowerShell to handle video URLs.

  Some examples I’ve seen have piped a binary stream from youtube-dl to an external player using the Windows Command Prompt as demonstrated :

  youtube-dl --output - "https://youtube.com/mygroovycontent" | mpc-hc.exe /play /close -

  This works fine in Command Prompt as it does not mangle the binary stream. If you try and run the same command in PowerShell it doesn’t handle the binary stream so well and modifies the output, making it unreadable to the external player.

  In light of this I’ve written the following PowerShell function to get around this issue. It tries to mirror a similar function I’ve written in Bash (See : https://github.com/adamchilcott/.dotfiles/blob/master/.bash_functions.d/streamer.sh)

  The reason I’ve handled youtube-dl, ffmpeg and ffplay seperately is that defining the ffmpeg binary location in youtube-dl as an external program creates some issues when passing it in PowerShell.

  I was hoping that someone could take a look at my script and provide some feedback on what I have done here and if it can be improved upon or if a better implementation is already available ?

  Best,

  Adam.
