Here are typical command lines:

./ffmpeg -r 29.97 -s 320x256 -vd /dev/video0 -vhook
'vhook/imlib2.so -x 0 -y 0 -i ../etc/black.png' 
-vhook  'vhook/imlib2.so -c white -F
/usr/X11R6/lib/X11/fonts/TTF/VeraBd.ttf/12 -x 0 -y 0
-t  %A-%D-%T'

As I experiment, I might change the frame rate, like
to 30, or the size, like to 320x240. 

in the past I used:

./ffmpeg -vd /dev/video1 -vhook 'vhook/drawtext.so -f
/usr/X11R6/lib/X11/fonts/TTF/Vera.ttf -t %A-
%D-%T' http://localhost:8090/feed1.ffm

If I change any command line options, typically,
ffserver segfaults, or at least more often than if I
do not change options, and just stop and restart

I am using ffmpeg-7481. After that, the change to
http.c causes ffmpeg to fail with a "Could not get
stream paramters" error.

That part of the story at least.
