Hi all,

I just managed to compile the ogg vorbis encoder (www.xiph.org/ogg/vorbis) with
dmc v830.
This itself is a big step because the previous versions failed to do it. They
crashed with internal errors cgcod 2347 and cg87 
268.
The porting to dmc was very easy. I had to add only two defines and to fix two
mistyped function declarations and everithing 
was just fine. 
Because i know that encoding a wave file to ogg format is a very computational
process, and because i was curious about how dmc 
compares to vc in code optimizations and executable size, i compiled the
encoder with vc6 too and run both encoders several 
times against one wave file.

Here are the results:
both executables are static builds, 
the dmc switches are: -6 -ff -a8 -Nc -o -Aw -Ab -Jm -DNDEBUG
haven't touched the vc options

Size of compiled oggenc.exe file:
vc compiled- 1073152 bytes
dmc compiled- 1088028 bytes

average encoding time for first wav:
vc compiled-2m 00s
dmc compiled-2m 09s

Just in case i encoded another wave file:
vc compiled-2m 40s
dmc compiled-2m 51s

This are average times but the bigest deviation was 2 sec for both encoders.


Best regards

Hi,

I will send them the patches and the makefiles and i hope they will accept
them. 
It will be good to have support for dmc in a big and popular project like this.

Just one thing. Are this the optimal switches for compilation or there is a
better combination.

I'd modify the switches as follows:

-6    Omit, since I adjust the default anyway to be the most recent
processor.
-a8    Omit, this is the default for win32. The default anyway is almost
always what is desirable.
