Windows 7 can't render YV12

[fvisagie]

Hi All,

I'm processing some video with AviSynth, but can't get the YV12 video output to render on my system. My current system is Windows 7 Pro 32-bit on Core i5 @ 2.6 GHz with 4 GB RAM. Previously this worked on Windows XP. I need the video in YV12 format!

For what it's worth, the AviSynth script is (for now):

 
Input="Test.aac.avi"
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\ffms2-r309\ffms2.dll")
FFIndex(source=Input, cachefile=Input+".ffindex", indexmask=-1, dumpmask=0, errorhandling=3, overwrite=false)
Audio=FFAudioSource(source=Input, track=-1, cache=true, cachefile=Input+".ffindex", adjustdelay=-1)
Video=FFVideoSource(source=Input, track=-1, cache=true, cachefile=Input+".ffindex", seekmode=1, rffmode=0, width=-1, height=-1, colorspace="YV12")
AudioDub(Video, Audio)

Results are as follows:

VirtualDub 1.9.6 reads and renders the video
Windows Media Player 12 plays, but displays blank video
Media Player Classic-Home Cinema 1.3.1976 reports:

Media Player Classic could not render some of the pins in the graph, you may not have the needed codecs or filters installed on the system.

The following pin(s) failed to find a connectable filter:

How do I go about trouble-shooting and fixing this, please?

Many thanks,

run ripbot264 once. Missing YV12 filter will be automatically installed.
