"Not a clip"?

[Forteen88]

I get "Not a clip" in AvsP when I try this AVS:
a=Directshowsource("E:\video.mkv")

it's a x264-video.
What's can be the problem?

[poisondeathray]

You've got to return "a"


a=Directshowsource("E:\video.mkv")
a

a=Directshowsource("E:\video.mkv")
aThanks. I got another problem, "Interleave: video formats don't match", when I try to compare source vs encode like this:

a=import("E:\video.avs")
b=Directshowsource("E:\video.mkv")
interleave(a,b)

[poisondeathray]

What formats are they? Use mediainfo. If they differ (e.g. resolution, fps etc...), you have to change one to match the other in order to use interleave

what more is "etc"?
I'm changing the resolution of the source (in the AVS), to the same as the encode.
Source.avs:
AVCSource("E:\00001.dga")
AssumeFPS(24000,1001)
dull = last
sharp = dull.LimitedSharpenFaster( ss_x=1.4, ss_y=1.4, strength=100, overshoot=1)
Soothe( sharp, dull, 20 )
Spline64Resize(1280,720, 8,2,-2,-2)


thanks

Still an error message? What is it?

Use AssumeFPS(24000,1001) for the other clip as well. 23.976 is an approximation

Use AssumeFPS(24000,1001) for the other clip as well. 23.976 is an approximationYeah, still "Interleave: video formats don't match". I did AssumeFPS(24000,1001) on the source but the encode should have that FPS also then, although it might not be as precise, so maybe it's better to write "AssumeFPS(23.976)"?

FPS has nothing to do with this. This error appears when colorspaces did not match. Make sure that Directshowsource("E:\video.mkv") outputs YV12. Most likely its not.

That's right. Interleave does not require matching frame rates.

Most likely its not.How do I make sure that Directshowsource("E:\video.mkv") outputs YV12? I noticed that my Windows 7 Pro 64-bit uses Microsoft's h264-decoder by default (maybe it causes the problem?), even though I installed ffdshow 64-bit. I used clsid's "Preferred Filter Tweaker for Windows 7", and set that it uses ffdshow 64-bit h264-decoder instead of M$ 64-bit h264-decoder, but noticed that M$ 32-bit h264-decoder is still on (because there's no alternative). Should I also install ffdshow 32-bit and set it as a prefered 32-bit h264-decoder?
Thanks

ConvertToYV12()

If you use Info() it will tell you what colorspace , and also other information

Are both h.264? Why don't you use AVCSource for both, and avoid directshow filter issues?

Why don't you use AVCSource for both, and avoid directshow filter issues?Ok, thanks, I'll use AVCSource for both instead (although it's annoying that DGAVCDec seems to want a clean h264, not a MKV, otherwise it mentions some errors :P), then there should be no issue. Yeah, both the source and the encode is h264.

I tried using these lines in the screenshot-AVS before, but it didn't help:
a.ConvertToYV12()
b.ConvertToYV12()

EDIT: Ok, thanks Gavino.

You need to say
a = a.ConvertToYV12()
b = b.ConvertToYV12()

or write the whole script as
a=import("E:\video.avs").ConvertToYV12()
b=Directshowsource("E:\video.mkv").ConvertToYV12()
interleave(a,b)

But you better resolve the problem with your decoding chain, because otherwise colorspace will be converted twice (YV12 -> something -> YV12), which is not so good for quality comparison.

How do I make sure that Directshowsource("E:\video.mkv") outputs YV12?

Thanks

Sorry I can't help you with 64bit version.
EDIT: well since avisynth is 32 bit then most likely it uses 32bit filters so yes, try 32bit ffdshow.

I used the same decoder (DGAVCDec) for the encode as well, so it turned out well (although it's a bit timeconsuming making a project in that decoder-program). I didn't have to use ConvertToYV12() then. I'll try installing ffdshow 32-bit also then (for cases when the source is VC-1 or other).
I hope Avisynth 64-bit is released soon :)
