Avisynth Error

Amo-Chan · Post by **Amo-Chan** » Wed Sep 05, 2007 12:23 am

I'm trying to open a file via avisynth with vdubmod. I've been able to do it before, but now I'm getting this error message: Avisynth Failure Couldn't locate decompressor for fourcc dvsd.
What does this mean and how can I fix it?

Set DV decoding to 'libavcodec' in ffdshow's VFW. If you don't have ffdshow (or have an outdated version), you can get it here:
http://sourceforge.net/project/showfile ... _id=173941

Then use AVISource as usual. That should work.

I've had problems with ffdshow in the past though. My computer doesn't seem to like it. Or at least, my version of Vegas doesn't. I lose all visuals. I'll try it though...just to be on the safe side.

Ok...I just did that and I got the same error.

The only other thing would be to make sure it's enabled in the regular Video decoder section and use DirectShowSource instead of AVISource. It may also work without messing with ffdshow and just using DirectShowSource.

It is possible to simply choose one format for ffdshow to decode if others give you problems. Just by switching all the other formats to 'disabled' in both VFW and regular Video decoder configuration dialogs.

can you open the file in vdub without avisynth?

Darn it...no. I get a vdub error that says the same thing.

DVSD is the FourCC for DV AVI; the error is telling you that you don't have a VFW DV codec. You can get Panasonic's offering <a href="http://www.free-codecs.com/download/Pan ... m">here</a>; install that and it should open in VDub.

Actually, I do have that codec. I downloaded it and installed it and tried to open the file before I came to the forums.
