Avisynth: Problem with xvid video?
 

Hi i had no problem until recently, trying to open the script media player tells me can't find decompressor, then i add the line convert to yuy and it gives me 1/2 purple screen, then i add convert to yv12 and it can't find decompressor again, i can play movie without the script so it's not a codec problem, i uninstalled and reinstalled avisynth2.5 but it didn't work, help

Try to open the file in Vdub, and look at the error reported.

I have been having the exact same problem!!! It only happens on certain divx or xvid sources, never on dvds. See my current thread in the Avisynth forum, http://www.kvcd.net/forum/viewtopic.php?t=4750. So far I haven't had any luck fixing this!When I only add the line ConvertToYUY2 after loading the avi, I get the same half-purple screen with an error message on top which reads Plane Difference: Only planar images (as YV12) supported! ([ScriptClip], line 1). So I tried adding the line ConvertToYV12 before the MA scriptclip section, but tmpgenc reports that the avs file can not open or is unsupported. If I try and load the same script in virtualdub, it reports Couldn't locate a decompressor for format 'YV12'. I reeeaaally hope someone can help us out on this one!

J-Wo,
install avisynth252 with ffvfw :!:

from Changelist of avisynth252:
Added light version of "ffvfw" to the installer. No "Cannot locate decompressor (YV12)" messages.

If Jorel's advice don't work for you - try to modify your script this way -
ConvertToYUY2()
undot()
ConvertToYV12()
Limiter()

It work for me on old codec (DivX 3.11) movies....
