Hi all,

Platform: Mac OSX 10.9 or 10.8 or 10.7
FFmpeg: recent
mplayer: tip of svn

phenomenon:
use such command ./mplayer -vc ffh264vda ..../content.mkv 
to play a H264 content.
The memory usage will increase very fast, 
and exhaust the whole system in minutes.

Condition to reproduce
1. -vc ffh264vda is necessary
2. a H264 content is necessary, use HD content will be easy to observe.

Analysis:
