Replying to [comment:1 Thilo Borgmann]:
> If there is no 30 fps mode listed under supported modes, there's nothing
we can do about that - the OS has changed its mind of what to support (or
the drivers, is there something involved from magewell?).
> Testing the modes is not without a chance some modes just declare 60 fps
but gives you 30 in the end.
Hi Thilo,
I appreciate your response to my ticket. To provide some additional
information, I ended up writing a command line app in Swift to achieve
what I'm trying to do (simply record a video from an external capture
device via the command line) and found that using Apple's AVFoundation
framework, I can record videos from the magewell capture device at 30fps.
Given this new information, would that still point to a problem with the
drivers and/or the OS? Not at all trying to challenge what you're saying,
just want to provide some more context in case it indicates anything.
Really appreciate the work you guys are doing here, and any help you or
anyone else can provide here.
