Extract embedded visible video metadata from thermal video

[CozmoxJC]

I'm kinda new to drones and metadata processing, so I'm not sure if I have some misconception.

When I filmed a video with Anafi-USA in thermal view, does the drone capture the thermal data and visible data all at once? If that's so, is it possible to extract the visible video(or images frame by frame) by metadata processing with PDrAW? and how do I do that?

Secondly, is it possible to convert into a temperature array per image through the embedded thermal video metadata?

Take a look at the pdraw-vsink test program, it picks out the battery-percentage metadata as an example. Any other metadata should be available.
