Only YV12 output is supported (because that's all the vpx library supports).
We will file this report as an enhancement request.

I tested on Win7 x64, but I an unable to duplicate your actual output.
I can successfully render using VMR9.
We would need more information in order to duplicate the behavior on your
system.
Are you running Win7 inside a virtual machine?
When you right-click on the video renderer's input pin, to get a property page,
what color-space format was negotiated between the pins? Was it YUY2?
It sounds like you're running in a VM, and so your video renderer doesn't have
direct access to the video hardware (or something like that), so it only
accepts packed YUV formats on its input pin.

Windows 7 was running under VMware Workstation 7.1 (should also work with
VMware Player 3)
VMware system tools were installed, thus having VMware video accelerated
drivers (Aero theme works)
I have tested both Theora and WebM, Theora was using YUY2.
I was using VMware to make screencasts showing how the html5 <video> activex
plugin was working with Internet Explorer, but when I've tried with WebM it
didn't work.

FYI
According to Frank, libyuv supports conversion from YUY2 to I420. Maybe you can
call the function to do the conversion. Here is the
code.(http://code.google.com/p/libyuv/source/browse/)

The function YUY2ToI420 in planar_functions.h does conversion from YUY2 to I420
The function I420ToYUY2 in convert.h does the opposite.
I'm not sure how you would hook those up for graph edit, though.

We'll need to modify the filter. If we have source code to do the conversion,
it shouldn't take long.

Note that YUY2ToI420 is fully optimized, but I420ToYUY2 is not yet.
If its for a real application, I'll be sure to prioritize optimizing it.

We have the old optimized versions of packed-to-YV12 conversions from
the On2 days (Scott's "on2 blitter"). We also have unoptimized
conversion going the other way, from the old On2 Flv SDK.

I've done the optimized I420ToYUY2 now, which should be checked in Monday.
C code ConvertToYUY2Buffer (1135 ms)
SSE2 ConvertToYUY2Buffer (203 ms)
5.6x faster.

YUY2 is checked into libyuv, if someone wants to try hooking it up to graphedit.

I added support for YV12, I420, UYVY, YUY2, YUYV, and YVYU formats. If you
can't build from sources, let me know and we'll make arrangements to get you a
binary.
