Comment (by arboz):

 seems the system crashed while I was writing this...

 You guys literally fixed this while I was sleeping.
 GREAT!!, Thanks.

 My only comment is that I got the clue from this post:
 http://ffmpeg.gusari.org/viewtopic.php?f=8&t=1651
 which has a few right and wrong answers and is circa v2.4.1

 So I did look at the ''configure'' file and decided to try just removing
 the dep for libsdl2 with no additional flags.

 That actually does reliably work because of:

 {{{

 --disable-sdl2           disable sdl2 [autodetect]
 }}}

 and there is a block of scripting in the configure file to look around for
 the sdl/2 headers to support that, and sure enough, it detected my lack of
 libsdl2 and did not  build ffplay

 Now I still wonder if it would be satisfied with the pre-compiled binary
 framework (headers included)
 from:  https://www.libsdl.org/download-2.0.php
 which claims:
 {{{
 Mac OS X:
 SDL2-2.0.5.dmg (Intel 10.5+)
 }}}

 However, my testing will need to wait a bit for that; in the meantime, I
 can still have access to the command-line ffmpeg tool and the codecs.

 Thanks again.
