Clobbering CFLAGS is not nice.

Hi,
I finally got around to overriding ogg_malloc etc and running through my
memory manager.  Thinking of limited memory consoles like PS2, I was
somewhat alarmed at what I found .. Admittedly I am using vorbisfile but
that’s because its so easy to use :) .. 
Per ogg file my memory manager is telling me it is using 885,201 bytes
per file (I thought I would maybe get a constant overhead and lower
overhead per file but its 885k each time).  
Ov_read reads 17k at a time in my streamer, and reducing it (to say 7k)
made no difference.
Is there a way to get this right down?  Remove vorbisfile I assume is
the first thing (though I am loathe to do right now due to the extra
complexity involved).  Mp3 currently uses about 32k of different buffers
per file which is extremely efficient memory usage for consoles, is
there any way vorbis might be able to get this low?
I havent had a look at static usage yet, id have to take a look at the
map file for that.
Any ideas or comments appreciated.
Cheers

How much RAM does a PSX2 have?

Vorbisfile shouldn't be a big overhead over straight libogg/libvorbis;
if it is, it's time we do something about it.

That's way too much, I think... you might forget to free memory?  If
you've
overridden alloca() as well, you need to free that memeory at function
exit of the function that did the alloca() (or per C block, even).

That's not right; the tightest mp3 decoder I've seen needs about 48k
R/W memory, and there's not much opportunities left to reduce that.

There's work being done to reduce Vorbis memory usage (as well as cpu
usage, and cache pressure).

You can mail me your malloc() etc. implememntation, and I'll have a
look at it; and/or the raw output of your mem usage experiments.
