[packman] ffmpeg memory leak

[Vladimir Psenicka]

Hi.

I have discovered that when I am converting mkv audio (DTS-> AC3)  ffmpeg eats 
whole ram (4GB) and system is swapping then computer is unusable. When I 
converting "avi" file everything is ok. I think problem is in mkv container a 
how ffmpeg works with it

rpm -q ffmpeg
ffmpeg-0.6.25320svn-2.pm.4.1.x86_64

Command to reproduce:
ffmpeg -i input.mkv -vcodec copy -scodec copy -acodec ac3 -ac 2 -ab 128k 
output.mkv
