Hi

With this script:LoadPlugin("D:\Projets\RealAnime\output\avs\Convolution3DYV12.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\Decomb510.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\Dup.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\FluxSmooth-2.5.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\MSharpen.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\MSmooth.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\UnDot.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\asharp.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\MPEG2Dec3.dll")
anime = DirectShowSource("source.avi")
anime = EnsureVBRMP3Sync(anime)
anime = UnDot(anime)
return animeI get sound out of sync after 1 minute.

Using this code:LoadPlugin("D:\Projets\RealAnime\output\avs\Convolution3DYV12.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\Decomb510.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\Dup.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\FluxSmooth-2.5.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\MSharpen.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\MSmooth.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\UnDot.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\asharp.dll")
LoadPlugin("D:\Projets\RealAnime\output\avs\MPEG2Dec3.dll")
anime = AviSource("source.avi")
anime = EnsureVBRMP3Sync(anime)
anime = UnDot(anime)
return animethere is no sync problem. Any idea?

:confused:

[edit]

Oh... I'm using AVISynth 2.5.3 :)

Have you tried specifying the framerate for the clip in DirectShowSource with the fps parameter?

Check the samplerate. DirectShow might report a wrong samplerate. What's your video/audio codec?

Video: WMV9
Audio: MP3 VBR

about FPS, I let it alone.

i've seen libMad in ffdshow do some odd things with mp2/mp3

like the samplerate halving on the first load, but being fine on the second :confused:

try a different mp3 directshow filter and see what happens.

I know this thread is old but I'm finding exactly the same behavior. Audio is out of sync when imported using DirectShowSource() but is okay when using AviSource().

I've never used AviSource() before since I use FFDShow, a DirectShow filter. I don't understand how I'm decoding XviD video with AviSource()...

Thank you...

activate FFDshow's vfw compatibility for the video codec you're trying to work with and then you can use it with AVISource.
xvid is vfw compatible thanks to the b-frame hack, so you can use it with AVIsource if it is within a .avi

FFdshow also includes VfW codecs, as used by AviSource.

Edit: ... as just mentioned by kemuri-_9 :)
