Troubleing with importing DV file into avisynth

[adamhj]

I captured the avi file, which has a dvsd for fourcc, from a DV. It plays well, but when i try to import it into avisynth, i'm troubled. avisource doesn't work as there is no vfw decoder for it. but when i use directshowsource it report that "unable to determine the duration of the video" and "unable to determine the duration of the audio" .

i tried to import the dvd into graphedit, delete the video render filter, then open the grf file with directshowsource, but it still report that "unable to determine the duration of the video"...

now, i don't know where is the problem, please give me some help.

You can either install a VfW decoder (Cedocida / Panasonic, look in the DV forums stickies) or use DirectShowSource. Make sure to set the frame rate -> DirectShowSource("C:\blah\meh.avi",25). Also upgrade to AviSynth 2.5.5 if you havent done so yet :)

set fps has no use, still the same error , and i'm using avs 2.55 already.

ok, i will try the vfw decoder, thanks~

eh...vfw decoder does work..but i can't process audio now...

Is your DV file a Type II DV? If not, you unable to process the audio of Type I within VirtualDub or AviSynth.

i recommend scenalyzer for capping - doesn't drop a frame even if you're running firefox in the foreground.

also, if you've got ffdshow, you can set it's VfW decoder for DV - it's nice and fast, and will return YV12 for you (though you probably don't want this if you work with NTSC DV).
