and actually the clip (using -frames 500) was 16.6 seconds long

PLEASE tell me somebody, why those interesting slowdowns of win codecs
with dga out exist?

yes, ffdivx is slower in 24 and 15 bpp modes than in 32 & 16 ones, but
there's a reason, why it is: no MMX colorspace transform when bpp is not
a multiple of 8

but this dll thing is too strange; theoretically DGA 1.0 can't make use of
-bpp, but actually it does!!! so again: why?

As you can see, ffdivx (at this bitrate) is still too slow on my machine
(as P1s don't have MMX2, SSE, 3Dnow! and like that, today's patch won't
speedup things for me, so yesterday's tests should be up-to-date in my case)

The only situation, when ffdivx performance was close to the dll ones'
occured when running -vo x11 in 32bpp X, so it's not useful, because
it's so slow...

I hope, I could send some useful information :)

Tibcu

(ps: and why is vfw dll not working with svga -bpp 16 and dga (-bpp 16) in
16 bpp X but working with x11 and dga -bpp 15 at 16 bpp X?)
