[theora-dev] Prob Stupid Questions

there is nothing in the Theora/VP3 algorithm that would require floating point on playback.  I don't think there is any need for floats in encoding either, though I'm not 100% sure.  A quick grep shows no 'float' or 'double' in the code tree.  YMMV

        Is theora based on Floating Point or Integer.
        I haven't looked at it much, but would like to help make sure it runs on
        other architectures ok. (especially: StrongARM (Zaurus) and DEC Alphas)
        Also as of now how efficient is the player compared to mpeg4?
        Aside from constant rewrite (as theora changes), why would someone not want
        to write a plugin to test it?
        Just new to theora, and wondering about things. I have compiled it on x86 and
        have been impressed with it so far. Though there are (of course) some rough
        spots (blended shading from one color to another is the only one I really
        noticed), and was wondering if I could help out with what I know best
        (porting to other archs, specifically those above)
