Two RealSense API questions

[OMora2]

Hi,

1. We are using RealSense SDK 2.17.0 on both Windows and Ubuntu platforms, and we see different that the supported rs2_frame_metadata_value on the two platforms are not identical, even when using the same sensor and firmware. Namely, RS2_FRAME_METADATA_FRAME_COUNTER and RS2_FRAME_METADATA_SENSOR_TIMESTAMP are supported on Windows and not supported on Linux. Is this a bug, limitation or are we doing something wrong? Will this gap be closed in the near time?
2. When calling rs2::frame::get_data(), a void* buffer is returned. Who is responsible for de-allocating this buffer, and is it 'valid' as long as the rs2::frame object is valid, or is it being re-used at some time for a new frame?

Thanks in advance!

The metadata documentation can assist with your first question regarding Linux / Windows metadata, in a section headed '​OS support'.
