Load Videos
This guide will show you how to load and play with videos loaded via the
fmdt.load_draco6(), fmdt.load_draco12(), and fmdt.load_window() functions.
We load the Draconids-6mm* videos as a list[Video] with load_draco6().

fmdt.db.Video
We can query if a video has any ground truths in our database with
has_meteors(). Let's use the first Draco6 video as an example:
v = d6[0]
>>> v
Draconids-6mm1.00-2750-163200.avi
>>> v.full_path()
'/home/ejovo/Videos/Watec6mm/Draconids-6mm1.00-2750-163200.avi'
>>> v.has_meteors()
True
>>> v.meteors() # returns a list of HumanDetection
[<fmdt.truth.HumanDetection object at 0x7f58c5fcdc30>]
In the background we have downloaded a videos.db file that has a detailed list
of our ground truth detections and the videos in our draco6, draco12, and window
categories.
Printing Diagnostics

TODO: fmdt.db_info() does not exist anymore!!
We can print some information about which videos fmdt can find on your system
with fmdt.db_info()

Detect from a Video
We can detect from a video using detect() just as we are used to.
