access violation due to my filter setup?

[sillKotscha]

good evening :)

I did a short tv-capture (with PicVideo_MJPEG) to test some nice filter settings, unfortunately VDub_Mod is crashing. But I'm not sure if it's due to the last VDub_Mod update or because of my filter chain?

Everything is ok until here:


LoadPlugin("C:\PROGRA~1\GORDIA~1\decomb.dll")
LoadPlugin("C:\PROGRA~1\GORDIA~1\Convolution3d")
LoadPlugin("C:\PROGRA~1\GORDIA~1\Cnr2.dll")
LoadPlugin("C:\PROGRA~1\GORDIA~1\MSharpen.dll")
SegmentedAviSource("D:\capture\capture000.avi")
ComplementParity()
FieldDeinterlace(full=false,threshold=15,dthreshold=9,blend=false)
crop(4,88,696,404)
Cnr2()
#ConvertToYV12().Convolution3d(0,3,4,3,4,2.8,0)
MSharpen(30,40,highq=true)
LanczosResize(544,288)


this script results in a normal preview (http://www.sahnau.de/skotscha/Capture_01.jpg)

but if I try to work with conv3D I get an access violation (http://www.sahnau.de/skotscha/Capture_02.jpg)...

disabling #FieldDeinterlace(...) results in the same error message

and additionally turning #MSharpen(...) off will screw up everything. The picture (the whole example_clip) looks like this (http://www.sahnau.de/skotscha/Capture_03.jpg)...

Is there something I can do or is it due to some filter [-settings], VDub_Mod or even avisynth??

thank you

regards Sill

Edit: I don't know why I didn't test cnr2 :confused: but I will...

Are you using Donald's fixed CNR2? Otherwise, that might help you out! It fixes a crashbug.

Edit: Hey! - Post #1000 - calls for a celebration. :)

hi shOdan,

yes, I've changed cnr2 to Donald's latest release but cnr2 has not caused the trouble because just disabling it...


ComplementParity()
FieldDeinterlace(full=false,threshold=15,dthreshold=9,blend=false)
crop(4,88,696,404)
ConvertToYV12().Convolution3d(0,3,4,3,4,2.8,0)
#Cnr2()
ConvertToYUY2().MSharpen(30,40,highq=true)
LanczosResize(544,288)


... ends up as screwed as my last picture/ link

this is strange because it seems that the clip has problems with conv3D, just disabling Vlad59's filter solves the problem - I've never observed something like that :confused:


I will see if v2.07 handles it...

regards Sill

[sillKotscha]

using v2.07 this problem didn't occure...



ComplementParity()
FieldDeinterlace(full=false,threshold=15,dthreshold=9,blend=false)
crop(4,88,696,400)
WNR("D:\Capture\wave.vcf")
Cnr2()
Convolution3d(0,3,4,3,4,2.8,0)
MSharpen(30,40,highq=true)
LanczosResize(544,288)


and it looks great... as it should (http://www.sahnau.de/skotscha/wnr.jpg)


cheers Sill

msharpen doesn't work in YV12 mode (yet).

I can reproduce the screwed up image! Seems to be a problem with the conversion routines.

There are some problems with error reporting, causing crashes instead of error pop-ups. CNR (and perhaps some other filters) seems to cause a deallocation error.

Donald - is it possible for CNR to try to deallocate some data that hasn't been initialized, if no frames has been requested?

Edit: Had a long look at the yv12->yuy2 conversion routines, and it seems to make some fairly strange assumptions about pitches. Seems like it'll take some work to fix. Thanks for the detailed report!

No.

[sh0dan]

ok - thanks! It's probably due to the conversion routines writing to invalid memory then.

[sillKotscha]

but only from YV12 (conv3d) back to YUY2 (msharpen) - cnr2 isn't affected and it seems that either conv3d or msharpen can't handle the conversion propperly.

Replacing conv3d by Fluxsmooth worked just flawless (no color conversion needed)...
