KNLMeansCL: OpenCL NLMeans de-noising algorithm [2018-01-29] - Page 12

LouieChuckyMerry · 23rd July 2015, 09:11

Hello. I've installed Visual C++ Redistributable Package for Visual Studio 2013 and the latest nVidia CUDA 7.0.28 on my Win 7, Intel HD Graphics 4000-nVidia NVS 5400M, i5 3320M machine and I'm trying to test drive KNLMeans CL, but the call:

Code:

LoadPlugin("F:\[0]StandAloneApps\MeGUI-2500(core)2443(data)0.3.5(libs)[Portable]\tools\lsmash\LSMASHSource.dll")
LWLibavVideoSource("SourcePath")
KNLMeansCL()

with the latest KNLMeansCL from Post #210 and SEt's latest MT AviSynth 2.6 leads to the error message "KNLMeansCL: AviSynthCreate error (1)!" and a handy little .txt file stating:

Quote:

Try adding device_type = "GPU" to KNLMeansCL.

LouieChuckyMerry · 23rd July 2015, 13:37

Thanks for the idea, Groucho2004. I tried that while I was reading the thread, but I forgot by the time I made it to the last page so I failed to mention it. Seems 10 pages is my limit...

This is a problem with the opencl compiler.... It should not happen, but I'll probably release a new version to fix it.
EDIT. It's only required a OpenCL driver, not all SDK.

I wondered about that but wasn't sure because my knowledge is limited, so I figured I'd update everything just to be sure that it wasn't the problem. By the time I'm 2112 years old I'll know everything

It seems my other laptop (Win 7, Intel HD Graphics 4000-nVidia NVS 5400M, i7 3840QM) can run KNLMeansCL (not sure why the other one, with the same graphics combo, can't), but the output 8-bit x264 video is a bit odd with Lsb_InOut=True. With any source (here's a sample, TestClipShawshank2) the call

Code:

LoadPlugin("F:\[0]StandAloneApps\MeGUI-2500(core)2443(data)0.3.5(libs)[Portable]\tools\lsmash\LSMASHSource.dll")
LWLibavVideoSource("D:\Temp\zzzTestClipShawshankTemp\TestClipShawshank.mkv")
KNLMeansCL()

outputs video that looks normal. However, the call:

Code:

LoadPlugin("F:\[0]StandAloneApps\MeGUI-2500(core)2443(data)0.3.5(libs)[Portable]\tools\lsmash\LSMASHSource.dll")
LWLibavVideoSource("D:\Temp\zzzTestClipShawshankTemp\TestClipShawshank.mkv")
KNLMeansCL(Lsb_InOut=True)

outputs video where the top half of the frame looks normal and the bottom half of the frame is, I'm not sure if this is correct, in a different color space. Here's a screenshot: KNLMeansCL(Lsb_InOut=True).

Any suggestion would be much appreciated.

foxyshadis · 26th July 2015, 07:39

You're encoding to 8-bit x264? Then you should use DitherPost to convert it back to 8-bit before feeding it to x264, it doesn't understand stacked video. It's kind of pointless to bother with that parameter for one filter; if you're using a full 16-bit chain, start with LWLibavVideoSource(...,stacked=true,format="YUV420P16") and continue from there. Your screenshot shows up broken because you didn't provide stacked video (that's what the In in LsbInOut means) but asked it to process as if it was; the filter won't convert from 8-bit to 16-bit for you.

http://avisynth.nl/index.php/High_bi..._with_Avisynth has more details on how to work with stacked 16-bit video.

LouieChuckyMerry · 26th July 2015, 09:17

Thanks for your help, foxyshadis

. I get the gist (if not all the details) of your reply, as I'm still a relative noob. I'm actually trying to take your kind advice from here, but am having trouble because it seems that SMDegrain and KNLMeansCL handle the Lsb parameter differently. I was trying to sort it out with 8-bit x264 because I thought it would be simpler (guess not

), but my normal script is:

Code:

SetMemoryMax(2048)
SetMTMode(3,7)
LoadPlugin("F:\[0]StandAloneApps\MeGUI-2500(core)2443(data)0.3.5(libs)[Portable]\tools\lsmash\LSMASHSource.dll")
LWLibavVideoSource("SourcePath")
SetMTMode(2)
SMDegrain(TR=3,ThSAD=400,RefineMotion=True,Plane=0,Chroma=False,Lsb=True,Lsb_Out=True)
F=DitherPost(Mode=-1)
S=F.FastLineDarkenMod()
D=MT_MakeDiff(S,F).Dither_Convert_8_To_16()
Dither_Add16(Last,D,Dif=True,U=2,V=2)
GradFun3(Radius=16,Lsb_In=True,Lsb=True)
Dither_Out()

Simply swapping out the SMDegrain line for:

Code:

KNLMeansCL(Lsb_InOut=True,Device_Type="GPU")

was causing problems. However, with the information from your reply:

Code:

LoadPlugin("F:\[0]StandAloneApps\MeGUI-2500(core)2443(data)0.3.5(libs)[Portable]\tools\lsmash\LSMASHSource.dll")
LWLibavVideoSource("SourcePath",Stacked=True,Format=YUV420P16)
KNLMeansCL(Lsb_InOut=True,Device_Type="GPU")
F=DitherPost(Mode=-1)
S=F.FastLineDarkenMod()
D=MT_MakeDiff(S,F).Dither_Convert_8_To_16()
Dither_Add16(Last,D,Dif=True,U=2,V=2)
GradFun3(Radius=16,Lsb_In=True,Lsb=True)
Dither_Out()

works perfectly. Awesome, thank you so much

. Does this means that SMDegrain has been spoiling me the entire time I've been using it?

Edit: do you know if there's a way to use KNLMeansCL(Lsb_InOut=True) with DGSource("SourcePath")?

Spoiling?

LouieChuckyMerry · 26th July 2015, 10:27

I've never had to manually add ",Stacked=True,Format='YUV420P16'" to my script before. Ahhh, perhaps you know: is there a way to use KNLMeansCL(Lsb_InOut=True) with DGSource("SourcePath")?

DGSource can only provide 8 bit format so you have to convert it to stacked first:

Code:

DGSource()
Dither_convert_8_to_16()

You might consider reading the Dither manual (at least the introduction and some of the examples), it helps understanding the basics of 16 bit processing. Cretindesalpes put a lot of effort into that manual.

Thank you. It seems really obvious once I see it.

That's an excellent idea. I've read sections of it in pursuit of an answer (and promptly forgotten what I read, ha ha), but I've never actually read the introduction. The wiki is even open in this tab stack so I've no excuse.

Thank you again for all your help

Yup.

You didn't specify lsb_in so it assumes you're passing in 8-bit and takes care of the conversion. In this case, lsb is actually implied by lsb_out.

I looked into this issue and I'm not sure if it is a bug in Dither or KNLMeansCL.

Test script:

Code:

colorbars(width = 1280, height = 720, pixel_type = "yv12").killaudio()
Dither_Convert_8_To_16()
Dither_Crop16(8,0,-8,0)
KNLMeansCL(Lsb_InOut = True)
DitherPost()

I tried mpc-hc and VirtualDub but both just throw "Access violation at...".

Debugging this with AVSMeter and checking "GetLastError()":

With the lastest Dither.dll (1.27.1), AVSMeter throws an error but GetLastError() returns "0" (ERROR_SUCCESS).

However, with the previous dither.dll (1.26.5), GetLastError() returns "0x0000007f" (ERROR_PROC_NOT_FOUND, "The specified procedure could not be found").

It works without error under these conditions:

As already reported by LCM, commenting out Dither_Crop16 and/or KNLMeansCL()
Using different values for Dither_Crop16, for example (4, 0, 352, 240)
Substituting KNLMeansCL with another 16 bit capable filter, for example dfttest

dither_crop16 is a... simple little function script in Dither.avsi, not a plugin in Dither.dll, it crops MSB and LSB separately and stacks them back together after that, and.. that's about it

Reel.Deel · 28th July 2015, 15:32

Have you guys tried Dither_crop16 with align=true? In AviSynth align defaults to false but in AviSynth+ it defaults to true. Not sure if it'll help with anything but it's worth a try, I guess.

Crashes just the same.

FYI:
Dither_Crop16(8, 0, -8, 0) - crash
Dither_Crop16(16, 0, -8, 0) - no crash
Dither_Crop16(8, 0, -16, 0) - crash
Dither_Crop16(16, 0, -16, 0) - no crash

Edit:
AVS+ r1825 does not crash whatever I try

Edit2:
HolyWu's correction below does fix the problem.

Speaking of this… there’s a little bug in Dither_crop16: it doesn’t pass the align parameter if the crop is only horizontal. It’s the case here but I’m not sure if this is related with the present issue.

EDIT: HolyWu got it first

Well spotted. Yes, that works.
