Problem with YV12 from AVS

[redfordxx]

Hi,
I have following problem:

When I have avs script and it's output is YV12,
1) I cannot play it in MPC(The following pins failed to find a connectable filter - see below)
2) I cannot open it in MeGUI(AVIStreamGetFrameOpen failed)
3) I cannot play it in BSPlayer (can't open file)
4) I cannot play it in VLC (does nothing)
however
5) I can encode it with x264 (directly from commandline)
6) I can open it in VD-MPEG2 (it writes Decompressor YCbCr 4:2:0)

Such problems are not present with YUY2 avs output.
Before I reinstalled my comp, all was fine.

Please Help, did I forget to install something?

R.

Have you installed an appropriate decoder? (ffdshow is a good choice.) There's more on this in the sticky YV12 FAQ.

oh, I had disabled RAW video...

and it has to be set twice DSh and VFW

DShow helped 1) and 3)
VFW helped 2)

but still 4) is a problem, but I don't care...

4) To VLC, an AVS file is just text. No way around it unless libavcodec adds their own code to act as an Avisynth server.
