 Summary of the bug: Looks like some filter sources (color, nullsrc,
 rgbtestsrc, smptebars, testsrc) do not free memory and probably holds all
 the frames during operation.

 Check the attatched image for memory usage during the first command:

 $ ffmpeg -f lavfi -i 'nullsrc=s=1280x720' -t 60 dummy.mp4
 $ ffplay -f lavfi -i 'testsrc=s=1280x720' -t 60

 (ffmpeg version git-2013-03-11-73b40e2)

 Using other filter sources, the problem doesn't occur. E.g.:
