DirectShowSource: Unable to determine the duration

[Zarxrax]

I have a video in a proprietary .GBM (gameboy movie) format. I can play the file through directshow, but I am not able to load it into avisynth.

It returns the error: "DirectShowSource: Unable to determine the duration of the video."

Is there any way to enable this to show through avisynth?

D..S..S..() in 2.5.7 Alpha 3 now has a framecount=nnnn option precisely to deal with these informationally challanged codecs.

Great! It's finally possible to load pictures with DSS!


DirectShowSource("D:\Captures\graph_picture.grf", fps=1, audio=false, framecount=1)

@Wilbert,

Do you need the "Color Space Converter", it generally does a pretty crappy job. What formats does the
"Generate Still Video" negotiate, I would expect YUY2 at the least.

Yes. It doesn't render without it.

According to GSpot it gives RGB24 to the Color Space Converter which gives RGB565 (???; 16 bit) to the video renderer. How is it possible to load such a 16 bit picture in AviSynth?

Btw, I don't know how to get that info from GraphEdit. According to this site (http://progdigy.com/modules.php?name=Forums&file=viewtopic&t=1810) the "Generate Still Video" filter is something from DirectX. It's not listed in the directshow filter list.

If I use the free DCImageSource file i get the same problem: http://dsp-worx.de/?n=13

It returns RGB24 with a Negative height, which indicate the image is upside down (which all RGB images are, DOH!) AVS doesn't like the negative height.

Fix in next version!
