How to open a DV avi with ffdshow and AviSource()?

[freezer]

I am trying to sort this out for another guy, but it drives me crazy:

ffdshow is installed and libavcodec for DV is activated.
DV avi plays perfectly in MediaPlayerClassic.

But in AviSynth the line

AviSource("V:\Deinterlacing\Orginal.avi")

just throws this error
AviSource: couldn't locate a decompressor for fourcc dvsd

which implies that it can't find the codec.

DirectShowSource doesn't work either.

I spent hours to search the web, avisynth manuals, forum after forum and now I have no idea what to do.

I know I could install the Panasonic DV codec, but that isn't what I want. I want to use ffdshow.

So if anyone has got any help - I would be most grateful.

Does it open in virtualdub? vdub and avisource use nearly the same path to open it, whereas MPC is totally different (even from DSS). If not, make sure you have it enabled in ffdshow's vfw config. If so.... well, you have a puzzle on your hands.

The problem is, that per default you can't open DV avis with AviSynth without an additional codec.

On my PC there is the mainconcept codec installed, so I am not really able to test the problem on myself. The guy who I am trying to help can't afford to buy the codec and I think it should work with open source too. But how?

Told him now to enabled ffdshow vfw. Let's see what happens.

Search for "cedocida_0.1.6.zip" it is a free, opensource, VFW, DV codec that IMHO stacks up very well. Precompiled binaries can be found on neuron2.net site.

Thanks, the tip with ffdshows vfw activation did the trick.
But I will also test the cedocida codec!

Thanks a lot.
