Wmv in avisynth

[redfordxx]

I have T2_1080i trailer from the Microsoft showcase page:
http://www.microsoft.com/windows/windowsmedia/content_provider/film/contentshowcase.aspx
It's 1:59

When I play it directly in BSP, it loads WMVideo Decoder DMO and I have following results
BSPlayer:
CPUTime 1:23 (including audio playback)
VirtualMemorySize 270MB
FramesPlayed/Dropped 2820/9
Surface: YUY2 DROverlay

When I open it in BSP via avisynth script DirectShowSource("T2_1080.wmv", audio=false) it is much worse:
BSPlayer:
CPUTime 1:53
VirtualMemorySize 350MB
FramesPlayed/Dropped 1287/0 (so it means avisynth itself dropped more than half of the frames?)
Surface: RGB32

In your case,Avisynth is the proverbial leaf that broke the camel's back.
If your system is dropping frames without avisynth, it will definitely drop more when you add on avisynth.

Key word here is RGB32. A colorspace conversion, twice the amount of data and no hardware video overlay.

Make DSS return YUY2 if you want to give it a fair chance.

OK, so I will change the question:
Is that normal that playing a file via avisynth is much more processing time consuming than direct?

Yes I thought so, but I don't know, how to get rid of it (=stay in YV12 all the time)
[edit]sorry I missed your last line

Make DSS return YUY2 if you want to give it a fair chance.But how --- DSS has no pixel_type parameter

[Inc]

DirectShowSource(string filename [, float fps, bool seek, bool audio, bool video, bool convertfps, bool seekzero, int timeout, string pixel_type])

It has ;)

[redfordxx]

It has ;)
OK, I'll download newer AviSynth, maybe it is the reason...
What is the difference between alpha and non alpha

[Wilbert]

v2.56a (actually a non alpha version) is a fix for v2.56.

Make DSS return YUY2 if you want to give it a fair chance.OK pixel_type="YUY2" helped...

but --- interresting: pixel_type="AUTO","YUV","YV12" made RGB32 output
