On a sample video file, using the above environment variable, 'ffplay4'
starts playing audio right away, but takes several seconds to display
choppy video.  It then hangs after the end of the file and keeps running
until I press Ctrl-C.

With the variable set, 'mpv' and 'mplayer both default to "xv" as the video
output.  'mpv' opens a window but never paints it while 'mplayer' opens a
black window.  The audio in the sample file plays and both players exit
otherwise normally.

Forcing "-vo sdl" in 'mplayer' opens a black window and the sample file
audio plays while a stream of:

[...]
Movie-Aspect is undefined - no prescaling applied.
VO: [sdl] 352x240 => 352x240 Planar YV12 
Movie-Aspect is 1.34:1 - prescaling to correct movie aspect.
VO: [sdl] 352x240 => 352x262 Planar YV12

scrolls up the terminal window.

Forcing "--vo=sdl" in 'mpv' seems to work reasonably well.
