Hi folk!
Please advice!
It is possible?
Task very simple capture frame from analog input (composite or S-Video) and go to the Avisynth script and see result in MPC or other player.
With kind regards yup.

Try building a graph in graphedit or graphstudio (http://blog.monogram.sk/janos/tools/monogram-graphstudio/). Connect your capture device to a video renderer. Let graphstudio build the graph, delete the renderer and save the graph. Then use directshowsource() to open it. I think you have to set a clip-lenght manualy. I have no idea if this works, but it's worth a try. :-)

EDIT: you could also try using ffdshow (activate all uncompressed formats). If the ffdshow icon is in your taskbar while playing video with your favourite capture tool, you should be able to put some avisynth-commands in the ffdshow-avisynth-filter. Not testet either :-)

Hi hanfrunz!
Thanks for idea. I find possibility using ffdshow in VirtualVCR. If I right understandt I need check Avisynth tab and load script. Also need I check Add ffdshow video source?
But I do not sure this only one solution for subj.
yup.
Unfortunately this approach do not work. I get error message from VirtualVCR.

@hanfrunz!
Yes.
I make file testds.GRF:
http://thumbnails14.imagebam.com/2657/94ba5026562166.gif (http://www.imagebam.com/image/94ba5026562166)
Avisynth script simple:
DirectShowSource("testds.GRF",video=true,audio=false,fps=25,seek=false,framecount=262140)
fft3dgpu(sigma=6,bw=32,bh=32,bt=4,plane=0,mode=1,precision=2,ow=16,oh=16,wintype=1,interlaced=true)
fft3dgpu(sigma=9,bw=32,bh=32,bt=4,plane=3,mode=1,precision=2,ow=16,oh=16,wintype=1,interlaced=true)

I open script in MPC and see only 320x240 video. I try change property capture pin to 720x576 but without success.
Please advice.
yup.
