We're getting closer:

GStreamer-H.265-V4L2SL-Gst1.0: GStreamer H.265 V4L2SL decoder for
GStreamer 1.0... ✔️

The statemless decoder appears to show it can do h.265, but it fails
all the fluster tests.

Ran 0/147 tests successfully               in 9.376 secs

I checked other V4L2SL decoders and items that previously passed are
failing now, so I think something is wrong or corrupted with my
system.

For some reason, my system seems unstable, so I might reinstall
everything, but it will be a slow process.  I don't know if my sd card
is wearing out, or something is wrong, but simple things like mounting
a thumb drive are taking a very long time.

I am not sure when I'll get back to this again, but I'll try to do a
re-install this weekend to see if I can get my system more stable.
