[Libav-user] Using swcale to crop picture

[Eric Beuque]

Sorry i forgot a word in my sentence: "I'm going to try libavfilter. I saw
it seems to provide a ***scale*** filter algorithm, so i guess libavfilter
can replace libswscale?"

What I means is libavfilter can totally replace libswcale? Or they should
be combined?
