Beginner stuck

[sargan]

Avisynth ver 2.60
Virtual Dub ver 1.10.4
On PC W7 64 bit (but those 2 apps are 32 bit)

Have used Avisynth before - but usually just running scripts supplied by others, admit no expertise in it.
Trying to learn more .... and got stuck at the beginning.

Followed the tutorial ... first couple of steps of getting 'version' to display, trimming & fading worked fine.

However when I go to next step of using avisource ... it fails

Scenario I have a short sample I cut from a large AVI file .. used VD in direct stream copy mode.
The sample is at this path: e:\Test\sample.avi

The sample plays happily in VD (& other players) so assume good file and whatever needed to play it is installed on PC ?
But when I try via Avisynth I get:

I get error AVISource: couldn't locate a decompressor for fourcc dvsd (AVISource(E:\Test\trial.avs")

reduced to single line trial.avs script:
AVISource("e:\Test\sample.avi")

Did a bit of Googling around and found comments here that VFW codec may not be correct.
installed the FFDShow codec pack (32 bit & 64 bit)

No difference - same error.

Also found comments here if avisource won't work use DirectShowSource

So instead changed script to:
DirectShowSource("E:\test\sample.avi", 25)

Opened in WMP this plays but audio only - no video
However if I open in VD both Audio & Video fine.


So must be missing something (or config) ... welcome some help.

Also attach media info for the sample (PAL)


(keen to learn but struggling)

Use LWLibavVideoSource (avisynth.nl/index.php/LSMASHSource) instead, it doesn't depend on installed codecs.

You have a "dvsd" codec. It seems you should install a Panasonic VFW DV codec. Use google to find where to download it.
Try ffdshow/ VfW configuration panel/ decoder tab/ enable DV decoder and/or enable uncompressed.
Or install the cedocida vfw DV avi codec.

I ran a whole load of CV captures last year (same PC) why would it now need another codec ... just want to learn.


Also if I load file direct into WMP or VD it play OK ? would that not suggest I have the correct DV codec installed ?

I'll go look for Panasonic DV anyway

Tried that same error (except LWLibavVideoSource instead of avisource)

Installed PANADV codec

still runs with audio only (DirectShowSource)

however AviSource now runs audio & video ..... no idea how it worked previously as do not recall ever having installed this before.


Thanks for your help ... I can go back to tutorial ..... happy to take any other comments on why it wouldn't work.
