it would be poss
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.

To libavcodec/vc1*, yes
An easier choice may be parallelization of the
scale filter: It is possib

The vc1 decoder could need frame parallelization.
That being said, what normally happens is that
you decide on which part of FFmpeg you would
like to work on and start sending
Logically - codecs, especially on the encoding/compression side, or filters.
In general, as a place to start, it could be anything where people feel
processing is a little bit slow, does not rely too much on library calls
(stdlib, etc.),
and where the serial / non-parallel algorithm is not too

What part of FFmpeg are you interested in Parallelising?
