[Theora-dev] FW: libtheora in WinCE or PocketPC?

[illiminable]

I dunno about PocketPC 2003, but in theora-exp there are build 
configurations for windows mobile 5 pocket pc's.

Incidentally, i found that theora-exp while making a very noticable speed-up 
on the desktop make almost no noticable difference when i tried it in 
directshow on the wm5 pocket pc. Performance was pretty average, especially 
if the video isn't the same size as the display area. With controlled 
content, it's acceptable, for random content people might try putting on 
there from their pc, it's kind of hit and miss.

If you do happen to do some arm optimisation let us know!

Cheers,

Zen.
