we use clockoverlay to write date and time over a video stream. we've 16, 32 or
more parallel pipeline 1-5 fps and all have a clockoverlay. after we try to
find which cause high load it turns out if we remove the clockoverlay then the
load drops from 4 to 1.5 on a p4 celeron 2ghz. it's may be not a big problem on
modern pc, but as we like to run it on older machines wehere this elements
cause real high load it'd be nice to fix. not to mention it probably produce
such a huge load on moder cpu too just we still not recognize it.

ps. we encode the 16-32 video stream vide xvidenc (scale, colorspace etc). and
all of this case 50% cpu and 1.5 load while which clockoverlay the load goes to
4!!!
