Hi,

The attached patch removes CPU dependency of VOFW value defined in the "libscscale/
swscale_internal.h" file, so 21503 is used as default.

There is a comment in the source code that VOFW 2048 works faster on the PPC CPUs,
but maybe this information is outdated or at least maybe the slowdown is small
enough to be ignored and use VOFW 21503 as a default value for all types of the CPUs.
I'm not able to test the speed on the PPC, but maybe someone can do this?

I personally always repleace VOFW to 21504, because 2048 is really too small these days.

Regards
