Get realsense camera status

[GMari3]

Hello,

I'm using librealsense 2.16.0.221 and a D430 camera model. I'd like to know, from my application, wheter or not the camera is already in use (e.g., opened inside the RealSense Viewer or by another app).

Is there a camera option for this purpose?

I was not able to find anything in this regard, the only thing I found is the option RS2_CAMERA_INFO_CAMERA_LOCKED but it is not supported by my device (I checked it with the rs2::device::supports() call).

Thanks for your support!

get_active_profile looks like it would meet your needs.

Thanks! It can help even if it doesn't entirely fit my needs. I was searching for a way to access to that info before starting a streaming. get_active_profile(), instead, can only be used after a rs2::pipeline::start() call.

Maybe use a config class instruction that precedes the pipeline instruction, like Resolve.
