Bug in YtoUV ?

[AVIL]

Hi,

When I use YtoUV with a clip as "Y" parameter and all parameter clips (U,V and Y) are YUY2, Virtualdub crashes inmediatly with a violation error. If I omit Y parameter virtualdub crashes after processing about 60 frames. If i convert all clips to YV12, YtoUV works flawlessly. As a help, Virtualdub show the first frame before crash. This frame has width as chroma (388, a half of expected -as original clip was 768-) and height double of chroma (1152 instead of 576). My avisynth.dll is dated 11.08.2006. Some time ago (i dont remember how much) this functions work properly with YUY2.

There is no official 11.08.2006 release of avisynth.dll. WIlbert put a personal compile of 2.6 up for those wishing to experiment with the new colour spaces. It does not have most of the fixes in 2.5.7 and has a lot of untested new code.

I seem to remember fixing something in the YtoUV routines a while back, try the 2.5.7a3 release.

@IanB

I've installed the version you suggested and the problem is dissapeared.

Thanks.

So the bug also present in v2.56?
