My point is why are you expecting python help on the subprocess function here?  I also wondered who your audience was? 


I've already posted that I wasn't going to help with vlc.  A hint though, if you have a working command that outputs to stdout all you need to do in python is

import subprocess

subprocess.call(command)

That's as far as I will take this.

Btw -  this did not work...

It does because I use it daily in an extra I use. However as you doubt me you really need to find a good python forum where you can get the help you need.

it will open VLC, but the actual stream is not being piped in...

My full code...

import os
import sys
import subprocess


os.chdir('G:\\VLC\\')

startupinfo = None
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW


process = subprocess.call([
'vlc',
'--ffmpeg-hw',
'--avcodec-hw=any',
'dshow:// :dshow-vdev="Video (00 Pro Capture HDMI 4K+)" :dshow-adev="Audio (2- 00 Pro Capture HDMI 4K+)"',

],shell=True)

You don't need to worry about pipes you just need stdout and like I posted subprocess send stdout just fine. Your code is more complex than my example

I am really sorry I am not going to help further you clearly need to spend more time developing and less time posting. I counted I had 50+ replies yesterday before I said I wasn't going to help which I've done a really poor job of.

got fed up in the end and built a workaround...Got a batch file to trigger a Python file, which then decides some stuff and choses which sub batch file to trigger for the correct STB...
