Well - it's of course easy to write dump code in C which will
not fit into registers - unfortunaly GCC doen't have to
smartest optimizer - so the programmer must sometimes help.

S3Trio doesn't support YUV - this disqualifies this card.... :)

Also I hope you will rebuild all your programs everytime some bug/improvment
will be made in each used library... :)
(As your CPU must be pretty borred already :))

No - it's one or two percent (in word)
As I said - I'm measuring with avifile & mplayer...
Difference has exactly this value! (seriously)

Because if you are using statics - the generated code is ineficient
(i.e. Micheal's MMX constants - I'll put there some short header file
where most of the used constant will be generated by two MMX instructions
(avoids memaccess and should be as fast as static version)

Have you tried it ?

I know - that's why I'll have to write something for myself...
