Er, I am afraid not - I have had to regress to an older version of the 
code, which already works with our own codebase.

I have tried to compile trunk ogg/vorbis/theora this morning, however. 

[1] Additional include directories

..fails to include ogg headers: had to change




The page http://xiph.org/svn/ certainly seems to indicate that the 
directory should be 'ogg', so either it is wrong or the vcproj.

[2] Additional Library directories

same problem, 'libogg' -> 'ogg'

[3] Static build files out of date.

build_theora_static_debug.bat, build_theora_static.bat and 
theora_static.dsp appear to be appropriate only for Visual Studio 6.

[4] Static build dsp converts to vcproj but doesn't build

With error "1>c:\xiph\theora\lib\enc\x86_32_vs\dsp_mmx.c(20) : fatal 
error C1083: Cannot open include file: 'codec_internal.h': No such file 
or directory".

'size_t' is also not defined, and this causes a compile error in ogg.h, 
and a knockon error later in the same header file in the declaration for 

...why on earth do the comments at the top of dct_mmc.c start ";//" ? It 
seems unnecessary.

I hope this is of some help. If someone can advise on fixes (and I have 
permission), I would be happy to spend a little time testing and 
checking in proposed fixes for these problems.
