AviSynth "freezes"

[vahegan]

Hi,

After I completed one encoding session, and was about to start a new one, avisynth suddenly refuses to work. It displays Version() OK, but as soon as I get to mpeg2source() or mpegsource(), it "freezes" (uses 97% CPU resource, with no output at all) and all I can do after this is killing the process from the task manager. I tried this with dgdecode.dll and with MPEGDecoder.dll, and with the old Mpeg2dec - whenever I am trying to get any video source, it hangs.
I rebooted - no luck, uninstalled, then reinstalled avisynth - I was on 2.5.5 - didn't help, went to the latest 2.5.6 beta - again, no luck. The strangest thing is that it just worked fine a couple hours before.

Can anyone give me a clue? I am desperate

Hmm ...

Mpeg2Source(..)
ConvertToYUY2

also hangs? I assume emptying avs plugin dir doesn't help?

ConvertToYUY2 I will try this when I get home, it's on my home computer only. But, I assume, DVD video is already YUY2? And I tried it on several sources, also on a MPEG1 source, and avisynth refuses do work :(. Emptying the plugins folder doesn't help, no. I also uninstalled avisynth and Gordian, manually cleansed the registry and Windows\system32 from whatever reminding of avisynth I could find there, and then installed the latest GKnot again (which works flawlessly here at work), and yes, the problem is still there despite of everything...

Yes, it worked after I added ConverttoYUY2
Thank you!

I guess some strange codec was doing the YV12 decoding. You can see that in VDub under file info. See YV12 FAQ Q13 what to do about it.

Yes, something strange is happening with my coding software. Haven't got any strange codecs - nothing more than On2 VP62 (mainly used), Ateme H.264 (which isn't vfw anyway), and the standard Xvid/DivX (mainly for decoding :) The strangest thing is, though, that now, whenever I go to Video/Compression in VirtualDub(Mod), the window to select codecs does not open anymore :((( That is, I am not able to do any encodings now (with the only option of using Nero Recode for H.264). Removed all codecs and coding software, cleaned up the registry, rebooted, reinstalled the codecs and software - nothing helps. I hate reinstalling windows but, I am afraid, I will have to do it if I find no solution...
