[XviD-devel] B-Frames

Hi,

hm, I wouldn't rely on the intel compiler. Well, I haven't tried 6.0 yet,
but I had problems with 5.0.1. Sometimes the intel compiler seems to perform
some too agressive optimizations...

btw: I don't really know how VDub's "show output video" option internally
works, but you need to additionally define BFRAMES_DEC (in case you don't
have already) if you want XviD to decode your b-frame content properly. Ah,
and don't use the "packed bitstream" option, it doesn't work yet. Instead go
for "DX50 compatibility" (well, I don't remember how the option was called
exactly...)

bye
Michael
