I want to use a resizing DirectShow filter but all I can find is the bicubic one that says your resolution has to be a multiple of 32 or something: that is one strict limitation.

also, what codecs has the least resolution limitations, divx4, divx5, or xvid. i tried a horizontal resolution /4 and vertical /16 with divx5 and i got all these pink lines. i would like to use divx5 but the requirement of 16x for both directions is also one strict limitation.

so if anyone can tell me of another directshow resizing filter, or can explain which codec is more flexible about the resolutions, please reply. i tried searching around on the forum but i couldn't find much.

I think all of the resizers have the x16 restriction because most video hardware has that dependency. By the way, the bicubic resizer always crashes on me, I use the Moonlight Scalar instead. It seems to be just bilinear, but it has also proven extremely useful as a format converter, allowing me to plug video streams together that otherwise would refuse to connect.

divx 4.12 doesn't have as many restricitons. I think height/4 and widt/2 is ok with it.

On the other hand, if you share your video files, half of your friends might not be able to watch them. I had a Geforce 2mx that was only capable of fullscreen hardware overlay with videos at height/16 width/16
