[MEncoder-users] Diagonal line while converting "portrait" video

[Etienne Châtaignier]

Hello,

While trying to convert xvid mpeg4 source to flv file via VP6, i'm getting
this result : http://echataig.free.fr/guest/portrait.png.

Dimensions of videos are 414x552.

I'm using the following command line :

mencoder input.avi -o output.flv -ovc vfw -xvfwopts codec=
vp6vfw.dll:compdata=onepass.mcf -oac mp3lame -lameopts cbr:br=64 -af
lavcresample=22050 -vf yadif,scale=414:552,flip -of lavf

Any help would be greatly appreciated
