Old files are missing after git-svn clone with revision range control

I’m trying to clone mplayer repository with git. Since there is too many revisions, I cloned with
git svn clone svn://svn.mplayerhq.hu/mplayer/trunk -r32000:HEAD mplayer-git

After the cloning, there’re 3 folders missing including ffmpeg, libdvdnav, libdvdread4, all of which are commited in very old revisions and has not been changed for a long time.
I guess it’s a strategy ignoring old files to save spaces, then I try

git svn clone svn://svn.mplayerhq.hu/mplayer/trunk -r1000:1250 mplayer-git2

The three folders still didn’t show up. I really don’t get it. Is there anyone who can help me?
