smdegrain crashing, how to solve?

[zerowalker]

Well didn't know what to write for the title.
But it's pretty simple, smdegrain is crashing the application which uses it (avs2avi, virtualdub etc), although virtualdub doesn't crash, it continues as if it was working, the the framenumber is stuck so it's just going infinite.

I tried many things, Avisynth+, Avisynth 2.6, made some faster settings for smdegrain, but it always crashes anyway.

I am not sure what to do, as far as i know smdegrain is just a simplification of the MDegrain, so in turn would mean it's MVTools that's the culprit?

I have updated MVTools to the latest: 1.11.4.5

So, any suggestions?
As this doesn't seem to be an Avisynth related problem, but rather the Plugin.

[feisty2]

you need MVTools 2.6.05 not mvtools 1.x

[zerowalker]

Oh, well got that one as well.

[zerowalker]

No ideas at all?

I thought of trying it on 64bit, but noticed that Dithering isn't supported yet.

Is it running out of RAM maybe? Tried using SetMemoryMax(int) ?

[zerowalker]

It shouldn't be, it's at 400mb or something when it crashes (differs a bit, but not close to 1.2gb at all).

Post your full script that causes the crash and if possible a small sample. There's a handful on unknown variables that may help in helping you (source filter, resolution, colorspace, exact Avisynth version, etc).

[zerowalker]

Nothing to post really, Avisource, RGB, 640x480, Avisynth+ and Avisynth 2.6 Alpha (both of them tested).

Tried to save with different Codecs, UT and MagicYUV same results.

Tried saving with VirtualDub, same results.

Can't really provide a sample as it's a bit private sadly.
But it's nothing special, a normal 640x480 RGB file, it was Lagarith Originally, but resaved it with ffmpeg to UT just in case if that was the problem (Lagarith can have corruption on decode, never happened to me though).

So i am totally lost really.

[Reel.Deel]

Are you trying to process RGB as RGB or are you converting to YV12 for processing? Also you're talking about SMDegrain and not SMDegrain Mod, correct?

[zerowalker]

I am converting it to YV12, thanks for mentioning that!

And i am also using: SMDegrain Mod (Didn't know it was called Mod, sorry for that).

You can at least give us your full script, can't you?

Here it is:

Avisource("Z:\TestGraph - ffmpeg.avi")
ConvertToYV12(matrix="Rec601", interlaced=false)
smdegrain(tr=3,lsb=true,thsad=300,lsb_out=true)

It might be helpful to run the script through AVSMeter and check the memory usage there. Also, have you tried different source filters (LSMASH, FFMS2)? I vaguely remember some trouble with Avisource and a lossless file.

[zerowalker]

Yes it is, and yes i have.

Though i have smdegrain lsb on.
But i have tried without the Dithering to 16bit and just the normal (2 stacked pictures) output.

Will do that, i guess you mean, run till it crashes, and post the CMD output?

EDIT:

I have not tried using anything other than Avisource.

I have tried 2 versions of the same file, or rather one filtered and one original. The thing though is that one was UT Video Codec, other MagicYUV, so tried both just in case there was a decoding issue.

Sorry, our posts crossed and I edited mine.

Yes, use the -l switch to create a log with AVSMeter and post that.

You should do that.

[Groucho2004]

The problem might be avstp which allocates memory beyond what is set with setmemorymax. I just ran a quick test with your script and an sd source and the memory usage was > 800 MB (4 threads) after a few minutes.

[Guest]

Is avstp built in to SMDegrainMod, or how did you guess he is using it?

The modified version of mvtools2 and dither.dll are using it. So yes, it's basically built in.

Edit: It seems that simply removing or renaming avstp.dll disables multi-threading. Should be worth a try for the OP.

I see. Thank you very much.
