Hi,
I'm using OBS to capture an arcade machine which initially boots into a 1920x1080 desktop, then into a 1280x720 game after a few minutes.
I've been testing with Elgato Cam Link & HD60 S cards so far, which both appear to lack hardware scalers.
My capture source is currently configured like this:
This works as expected if OBS is started while the game is running, but if it happens before, the capture will fail to start:
Checking with FFmpeg at this time, we can see that the input PC is still on the desktop:
Since these cards have no hardware scaling, only the current 1920x1080 resolution is exposed, so this makes sense.
A short time later, the game boots and the desired resolution is now available.
But OBS doesn't try to re-open the capture device after the initial attempt fails. Manually deactivating and activating the source again works, but I need it to be able to recover automatically for my current use case.
Using device default for resolution doesn't work either, as this will just capture the desktop and then freeze up when the resolution changes:
At this point, the game has booted but the capture is frozen on the last frame before the resolution change occurred.
There is nothing further in the log and the source has to be reactivated manually.
Just wondering if anyone has any ideas on how to potentially work around this.
Apologies in advance if a similar issue has been posted previously.
