To process multiple slices at the same time - would depend on whether
independent slices could be scaled without data dependency from other
slices.
If there is data dependency, then it would be more difficult.

Thank you for any contribution!
Are you referring to the file
libavcodec/vc1.c ?
To libavcodec/vc1*, yes
An easier choice may be parallelization of the
scale filter: It is possible to let libswscale
work on slices, working on several slices at
the same time should allow for a big speedup
for some conversions.
I don't think this will work. libswscale makes very specific
requirements on how you scale by slices, and it doesn't look like you
can actually scale different slices with a different context.
I'm not a libswscale expert, though.
