Avisynth error when loading a script in virtualdub, please help

[auto7890]

I made a script like this:

DirectShowSource("file.flv")

I created a text file with .avs extension. Then start VirtualDub and use File/Open video file... to open this script. But then virtualdub complained with a avisynth error. When I click ok, virtualdub remain with a blank window, and I do not see my "file.flv" loaded, please help- see screen shot

1) please post a Mediainfo report about the FLV file ;

2) according to the error message, you'll have to either use Crop() or do a colorspace conversion ;

3) unless your Avisynth intermediation includes additional processing, you'd better use the FLV input plugin instead ;

4) Windows 8 ????? Good-luck with that

1- its AVC video -

2- Im not sure how to do either considering the file has not loaded yet in virtualdub, is there an example on youtube ?

3- do you know the download link for the FLV plugin ? there are so many, I may download the wrong one.

4- Yes

Hmmm, it's interesting that the H264 decoder outputs YUY2 instead of YV12 or NV12

Anyway, you can try the following:

AddBorders(1,0,1,0)
or
AddBorders(1,0,1,0).Crop(2,0,-2,-0)

Try using DirectShowSource("file.flv", pixel_type="YV12").

virtualdub complains that the "video does not have a video stream when I change - DirectShowSource("file.flv") -to- DirectShowSource("file.flv", pixel_type="YV12")"

does AddBorders(1,0,1,0) go inside the script ? if its a filter inside video it will not accept because the video needs to be loaded first.

[El Heggunte]

Open the FLV in Graphstudio, and tell us what is the H264 decoder that DirectShow is using.

And please, take the time to read Avisynth's documentation --- that's what I did, 6 years ago.

Ok, i installed the Flv plugin, now virtualdub also is asking for the AVC1 codec, where can I download that ?

[jagabo]

ffdshow has many VFW codecs including AVC1 (h.264). I think x264vfw includes a VFW h.264 decoder now too.

You can't add an odd number of pixels to the left or right edges of a YUY2 video.

My bad , jagabo is right.
