thanks

these look ok

designing a new configure/make system is on the TODO. i have some ideas, but
no implementation / final design yet.

I guess it's linking order. You have to move libosdep to the end of list of
libs, but probably before mp_msg.o because depends on that.

great!

It's already possible, at least demuxers export the metadata.
See test-stream for example.

Hmm. It would be good for win32 port too.
The problem is that big part of the GL setup is GLX (or WGL on win32, dunno
the Mac case) function calls. Maybe we need 3 implementations of this init
code, one for each major OS. And maybe a 4th for FBDRI on linux...
And a 5th for gtk-GL and a 6th for SDL-GL :)
Maybe it's worth to completely (in file level) separate GL and OS-dependnet parts.
