STILL MORE: working somewhat but with puzzling results. Based on info in the bug #5050, I spaced everything out. I have now gotten the recorder to actually save a snippet of video (a whole 2160 bytes!), and I did it by spacing the view visibility, prepare() and start() w.a.a.a.a.a.y out (like several hundred milliseconds for each step). I think what happens is that either bringing the surface VISIBLE has delayed processing or else the start() steps on the prepare() operation before it is complete.
What is now happening, however, is that my simple timer tickdown counter is getting wiped out. Is it now that the preview and save operations are causing my main process thread to become unavailable? I'm recording only 10fps at 176x144.
