I created that issue (a decade ago!), and haven't really found a need for
float, but that's because I'm usually working with raw data, and apply any
radiometric calibrations (i.e., conversion to temperature) outside of
GStreamer. I would probably just stick to the integer images and apply your
own mapping after the fact. If you want to get the floating point values
and still take advantage of GStreamer for processing, I'd probably just
pick a min/max float value and stretch the float to be 16-bit uint (e.g.,
