Again, Vdubmod + Avisynth ConvertToYV12 Decompressor

[rookandpawn]

MY avs script says
movie.avi is a HFYU (HuffyUV)


AviSource("movie.avi")
ConvertToYV12()



I try to open in VirtualDubMod and it says "Couldn't locate a decompressor for format YV12"

So I go into my FFDShow VFW Configuration, go to the Decoder Tab and Click AviSynth, making sure YV12 Input Colorspaces is clicked along with all the other checkboxes, I also go into my FFDShow Decoder and also do the same thing.

So i check to see if my registry actually now has
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Drivers32 and check for VIDC.YV12 and its not even there.

I know many have offered solutions for saying "Download Xvid and install then you can open avisynth script in Vdubmod with YV12" Or "Just use YUY2 instead"...

Okay so FFdshow's VFW configuration lists YV12 in a subpage of Avisynth yet its not "good enough"? Confused. I'd really like to use FFDShow. if i cannot why does it have a VFW section?

Also, why can MeGUI open a script with YV12 and get previews?? It must have its own internal YV12 ??

And sorry one more question, why is YUY2 included in Microsoft's WinXP (msyuv.dll) but YV12 is not?

please help

You've configured FFDshow to allow YV12 output in VFW mode. Still, VdubMod needs a YV12 VFW decoder, e.g. Helix YV12 VFW driver.

BTW
Why not try latest VirtualDub?
Contain internal decompressor (Directly decode uncompressed YCbCr (YUV) sources) and have more advanced Color Depth option...
