Trying to run streamlink with arguments through PySimpleGUI, getting permission denied

Question

As the title states, I'm trying to create a basic streamlink GUI with PySimpleGUI.

I've got [gui.Text('Stream link:'), gui.InputText()], and a bunch of other code (as of yet unimplemented options) which takes a stream link as an input, and runCommand('streamlink ' + values[0] + ' best -o output.ts') to use streamlink to download the stream to output.ts in the best quality.

runCommand is:

def runCommand(cmd, timeout=None, window=None):
    os.path.dirname(os.path.realpath(__file__)) 
    p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    output = ''
    for line in p.stdout:
        line = line.decode(errors='replace' if (sys.version_info) < (3, 5) else 'backslashreplace').rstrip()
        output += line
        print(line)
        window.Refresh() if window else None
    retval = p.wait(timeout)
    return (retval, output)

if __name__ == '__main__':
    main()

(Which I found here)

And this works as such:

[cli][info] Opening stream: 1080p60 (muxed-stream)
error: Failed to open output: output.ts ([Errno 13] Permission denied: 'output.ts')
[cli][info] Closing currently open stream...

As you can see, when I run streamlink through runCommand, it gets a permission denied error. I'm trying to get the output file in the same directory as the .py script is ran in, but I think runCommand might be specifying a directory I don't have permission to write to.

I don't know how I would go about specifying a directory for this command, can anyone help?

I got an output.ts under same directory as my scripy file. Link address patsted into Input, then 'go' click.

import os
import sys
import subprocess
import PySimpleGUI as sg

def runCommand(cmd, timeout=None, window=None):
    os.path.dirname(os.path.realpath(__file__))
    p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    output = ''
    for line in p.stdout:
        line = line.decode(errors='replace' if (sys.version_info) < (3, 5) else 'backslashreplace').rstrip()
        output += line
        print(line)
        window.Refresh() if window else None
    retval = p.wait(timeout)
    return (retval, output)

layout = [[sg.Text('Stream link:'), sg.InputText(key='-INPUT-'), sg.Button('Go')]]
window = sg.Window('Title', layout)

while True:

    event, values = window.read()

    if event == sg.WINDOW_CLOSED:
        break
    elif event == 'Go':
        runCommand('streamlink ' + values['-INPUT-'] + ' best -o output.ts')

window.close()

Here, runCommand take long time to work, so GUI maybe no response. Multithread suggested for it.
