Feature Request: RoughScript should work with RDP and RTSP

[RegEM]

My goal is to capture desktop videos, and videos via RTSP: On a PC connected to by RDP.

Not a complete surprise, but ffmpeg doesn't identify an input source while ran on a rdp PC.
And RoughDraft doesn't handle it either. See the #final code block below.
I've tried with two separate PC's.

I copied the DirectShow extension script, and created a rough RTSP, and GdiGrab extension. I saved them to the RoughScript extensions folder, and restart my shell. It didn't help allow the use of Receive-Media. I end up with parameter errors. Here's an example run.

Receive-Media -InputType GdiGrab -Time 10 -OutputPath .\Desktop.mp4
MethodInvocationException: C:\Users\<me>\Documents\PowerShell\Modules\RoughDraft\0.4\Get-RoughDraftExtension.ps1:900

     | Exception calling "GetDynamicParameters" with "4" argument(s): "Cannot index into a null array."
MethodInvocationException: C:\Users\<me>\Documents\PowerShell\Modules\RoughDraft\0.4\Get-RoughDraftExtension.ps1:900

gdigrab works fine with the Use-FFMpeg command.
So no doubt I can do the same for rtsp. It would be better to have it work in Receive-Media though.
$ffOut= Use-FFMpeg -FFMpegArgument '-y','-f',gdigrab,'-framerate',20,'-i',desktop,'-t','00:00:10', output.mp4
