Where to get the inputSettings list for createInput

[sadsunray]

Hello

I'm trying to write a little Replay app for a colleague.
But I can't find all the inputSettings I should setup while creating the input via
obs.call('CreateInput', {sceneName: 'TestReplay', inputName: 'ReplaySource', inputKind: 'ffmpeg_source', inputSettings: { "local_file": lastReplay.savedReplayPath, "looping": true }

I've already found the inputKind list and bruteforce guessed the local_file and looping, but can't get all the other options to set the input correctly.
Can someone please direct me in the right direction, where I have to look?

And another question, where can I setup the
Edit > Transform > Fit to screen
for an input via command? Because by creating my test input, it does not fit into the screen after importing.

Thanks a lot for your help.

I found a way via the Source Copy Plugin for OBS.
