As Michael points out there’s a slight problem with the CoreAVC For Linux patchset that enable Mplayer to take advantage of CoreCodec’s h.264 decoder — with recent changes in the sourcecode the old build_patch.pl script doesn’t produce usable output anymore.
There still is a way to compile Mplayer with the modification, though: Mithun Diwakar altered a patch to work against current subversion checkouts. How long this one will hold… we don’t know. But I think it would be preferable to fix up the patchbuilder. Maybe I’ll hack around on it during the weekend (no promise 🙂 ).
