Does the MAVSDK support _Visual Inertial Odometry_? The FAQ says No. However, a recent MAVSDK video was presented by an Auterion rep, and Auterion does support _Visual Inertial Odometry_.

Thanks in advance.

MAVSDK doesn’t support VIO.

Here are a couple of resources you might want to read to catch up on the topic.
