Well I think the term "resampling" denotes both scaling and conversion
operations, but I agree "color space conversion" is more clear.

I left it as before in this case, I don't think
s/filtering/manipulating/ is a good idea since it doesn't explain
whence the "filter" part of libavfilter comes from.
But I don't mind, if you prefer the other way or if someone can find
out some way to mention both "manipulating" and "filtering" I'll
I also extended the libavdevice description.
