std::vector<VideoCaptureCapabilities> holoscan::ops::video_io::enumerate_video_acquisition_devices(
    const std::string &backend_id = ""
)

Enumerate acquisition capabilities (concrete capture view per device).

If backend_id is empty, invokes every registered acquisition enumerator and concatenates results. Otherwise only enumerators for that backend are run.
