[FFmpeg-devel] Again problems with lavfi/swscale

I'm experiencing problems with commands of the kind:

ffplay in.avi -vfilters "slicify=20, format=FORMAT"

yuv444p,yuv411p,yuv422p,monow -> crash in RENAME(hScale)
rgba,argb,rgb24,bgr24,rgb555  -> crash in YUV2RGBFUNC()/LOADCHROMA
yuv410p -> chroma artefacts
rgb8 -> crash in PUTRGB8

Formats which work fine:
yuv420p, yuvj420p, monob
nv12, nv21 (with the patch by Ramiro)
gray, gray16

The commands without the slicify filter work just fine, so the problem
seems to depend on the slicification of the image (yes at this point
is clear that we need some testing system for spotting all these

If someone with more experience with libswscale wants to give some
hint it would be cool.
