Hello-
I'm using vMix Basic HD 16.0.0.115 x64 and I've been trying to get the API's AddInput function to load an RTSP feed via the web browser API but I haven't had any success—the documentation on proper syntax (or whether this is even possible with the current API) isn't entirely clear, but I've tried a few variations like

http://128.84.7.90:8088/API/?Function=AddInput=Image|c:\Users\filename.jpg (just to see if it works, pointing to a local jpg file)

or

http://128.84.7.90:8088/API/?Function=AddInput=Stream|rtsp://[usernamer:password]@RTSP.address/media.amp

and only gotten "No suitable function can be found"

If I just leave the "Function=" blank, i get a return of the xml file, so i know it's talking to vMix.

I can add the image manually to vMix and even trigger a shortcut to do the image (but not the RTSP stream), but no success using the API. Anyone encountered something similar & figured it out? Or am I missing something terribly basic?
