Open OBS borderless in an exact position on the screen

Hey All, we have been using an old custom player to capture video from a Decklink Mini Recorder and overlay it with a broadcast application called iControl. The developer of the custom app is long gone from the company and this player will not work with newer versions of Blackmagic Decklink mini recorder software. I was thrilled to see OBS work with the Decklink Mini recorder but to replace the custom software OBS studio needs to open borderless and at a specific position on the screen (X location 631, Y location 19). Can this be accomplished? Thanks in advance for your help!

Hey Aaron, we have an application called iControl that we use to "break-in" hub stations with network. This application has widgets that allow a user to select what they are routing. There is a video router destination that feeds a Decklink mini recorder card in the windows workstation. That widget has a window cutout for active video. I would like to use OBS as the capture window under the widget. To do this, it would be very helpful for the player to be borderless, but more importantly it needs to open at exact X and Y pixel coordinates on the screen. VLC can accomplish this with arguments in the "start-in" shortcut. I'm hoping OBS has something similar, because VLC does not play nice with the Decklink card and OBS does. Thanks!

Not that I know of. OBS is intended to be the final output, not an intermediate thing, so its output is either full-screen or in a window. I don't think you can position that window from OBS, but you might be able to with external tools, just like any other window. But that's still a Rube-Goldberg XY thing.

Can you rebuild that rig with other tools? Maybe do *everything* in OBS?

Not really. It is a broadcast centric application and has GPIs in and out, and also controls the Evertz router. Would be a big lift to build a custom panel. I will revisit VLC I guess.

Yeah, I'm surprised that you found something that VLC *doesn't* do and something else does. I think it's ffmpeg either way, so it might be just a matter of figuring out how OBS is doing it and copying those options to VLC.
