theora dev - May 2006 - FW: libtheora in WinCE or PocketPC?

Hi there,

I've found no answers to this question from Fri Apr 15 19:33:50 2005.
Are there any answers now?

Probably, but I don't really remember.

I'm not aware of any arm-specific optimization for libtheora. The 
autotools build includes a --disable-encode --disable-float config
for embedded use; to do the equivalent in a different build 
system, define the preprocessor symbols THEORA_DISABLE_ENCODE 
and THEORA_DISABLE_FLOAT and make the appropriate substitutions in the 
source file list based on the same conditional in lib/Makefile.am.

Glad you like it. You might also take a look at the theora-exp decoder 
library at http://svn.xiph.org/experimental/derf/theora-exp/ It has
some algorithmic speedups over the implementation in libtheora.

Hope that helps,
