Thank you for your answers. I was able to install Huffyuv with the following command:
../avisynth/ folder contains unzipped huffyuv package. But now I am stuck with
wine /usr/lib32/wine/fakedlls/rundll32.exe setupapi.dll,InstallHinfSection DefaultInstall 128 ../avisynth/huffyuv.inf
All I want is to get my 50i footage delaced to 50p and then slowed down to 25p to achieve slow motion movement effect.
$ wine avs2yuv ./sepfields.avs -o - | mencoder - -o hfyu.avi -ovc lavc -lavcopts vcodec=ffvhuff:vstrict=-1:pred=2:context=1
