YV12 Error

[Patap]

Hello,

I try to use Gordian Knot 0.82 beta 14 to convert VOBs to AVI.
After installed AVISynth 2.51 and use MPEG2Dec3.dll I cannot compress VOBs. The messagebox "VirtualDub Error" states "Couldn't locate decompressor for format 'YV12' (unknown)"
What is wrong?

Regards,
Patap

p.s. The same is the release version of GK 0.28.

you also have to install divx5 or xvid to have a yv12 decompressor available.

I had this problem, too, in Windows XP.
Also noticed that DivX was missing from available compression codecs in Vdub.

Solution was found in another thread here and on the DivX forum:
use REGEDIT
locate Hkey_Local_Machine\Software\Microsoft\Windows NT\Current Version\Drivers32
delete anything with a blank reference

Deleting/reinstalling DivX/Gknot didn't fix this.

This solved my Vdub error: "couldn't locate decompressor for file format YV12" and also the vdenc.log file error.

All is well now.

I have a severe YV12 problem - that is, when using converttoyv12() in my avs, I get a nice preview in GKnot, but when I encode with this, I get crap. If I use YUY2 instead, my preview screen will be all grey, but the encoding is ok.

My question: I use win 2000. If I open this registry folder, I find a lot of stuff. What do you mean with delete anything with a blank reference ? Is it the lines with no "Data" reference? Like i.e mixer9 or midi8 or wav4?

Hello,
I can't see any values with a blank reference !!!
Maybe should I add something i.e. vidc.yv12, but what to enter?

From mazzo advice:
How to use YUY2 instead?

[mazzo]

In the initial avs, you'll write someting like this:

avisource("hello_world.avi").converttoyuy2()

Yes, in the case of my XP registry, it was the lines with blank DATA entries which kept things from working. I deleted all the NAMES which had no data (there were 3 of them here) and rebooted.

I doubt that this cures all codec ills, though.
