Problems with Directshowsource and wmv-files

[HLW]

Hi!

I would like to decode some .wmv files using Avisynth and the DirectShowSource function,

Directshowsource("d:\sample.wmv", fps=25)

but in VDubMod I only get the message

AVISynth open failure
Evaluate: Unrecognized exeption

The .wmv files plays perfectly in Media Player Classic, and also on my laptop. I use Avisynth 2.5.4 on both of them. The computer in trouble is a Pentium 4, 3GHz with Windows XP

Have anyone else experienced this problem, or do someone know how to solve it?

Post all the filters listed in GraphEdit, when you open the WMV-file there, or make a sample file available.

Hi again!

I'm not very familiar with GraphEdit, but I hope this is what you asked for:

Raw Audio - WMAudio Decoder DMO - Morgan Stream Switcher - Default DirectSound Device

Raw Video - WMVideo Decoder DMO - Video Renderer

Edit: And the video plays in graph edit.

Strange. Could you unregister 'Morgan Stream Switcher' (which is called msswitch.ax, or something like that) and try again?

[HLW]

What do you mean by unregister?

[sh0dan]

Try adding "audio = false" as DirectShowSource argument. It may also help to enable ffdshow to accept "Raw Video", so video is sent through ffdshow before it enters AviSynth.

[Wilbert]

To register a directshow filter:

regsvr32 /s mmswitch.ax

To unregister it:

regsvr32 /u mmswitch.ax

[malkion]

Or copy this code as "RegShExt.inf" (rename .txt to .inf) then install it. Voila, instant register/unregister for your filters.

oh, right click your filters to reg/unreg.

I tried to unregister the mmswitch.ax, to set audio=false, and to enable ffdshow to accept raw video. But the problem is still there... :mad:
My filter graph is now as simple as:

Audio: Raw Audio - WMAudio Decoder DMO - Default DirectSound Device
Video: Raw Video - WMVideo Decoder DMO - Video Renderer

And the only place the video don't play is through Avisynth...

[Wilbert]

I have no idea what the problem is. Could you upload the clip somewhere?

[HLW]

I've tried with several different wmv clips. The last one was "goodbye.wmv" which is a clips that came with Windows. I have no place to upload it, but I don't think the clips is the case since I've tried with several.

Terribly annoying, because Avisynth is the by far best tool for my tasks..

[Kika]

I guess the problem is this crappy WMVideo Decoder DMO.
Did you try to open the video in TMPGEnc 2.5x directly?

[HLW]

@ Kika:

Hmmm...what should I do with the file in TmpgEnc? My wmv files play in all the other players I have tried.

If your guess is correct, is there any way to avoid the WMVideo Decoder DMO?

[Kika]

Hmmm...what should I do with the file in TmpgEnc?

Maybe convert it to AVI or MPEG? :D
