I was trying with the software decoder, everything is fine. This issue is
CrystalHD specific.

A line that trigger this state e.g.:
mplayer -fs -vc ffh264crystalhd -ao null sample-1080p.mkv

I've done some experiments with valgrind, when mplayer closed this memory seems
to be freed and is no more visible. So this 1MB/s memory increased is tracked
somewhere in the code. Maybe the h264 raw video stream ?

valgrind massif failed on my system.

finding the bad malloc line is not so easy.
