Unfortunately, in most cases I just don't *know* what the frame rate is 
going to be.  Only the code (elsewhere) that subsequently starts 
decoding/playing the video will know this.

I suppose I *could* set "sh_video->fps" to some arbitrary value (and 
"->frametime" to be the reciprocal of this), because in many (most?) cases, 
MPlayer seems to play the video OK, no matter what value I give it.  But 
this seems like a hack.  I don't really know for which codecs it's OK for 
me to give "->fps" an arbitrary, bogus value, and for which codecs I should 
leave it unset, so that MPlayer can tell the user that he neds to use "-fps".

It would be better to have the video decoding code not complain about 
"-fps" unless/until it really needs it.
