Dont see why it should make it red, however should for YUV use

Code:

Greyscale.Levels(127,1,128,0,255,coring=false)...

It's random/non-reproducible bugs, when using Prefetch(4). Masking and Levels(127,1,128,0,255) happens in RGB32.

Something like this works in avs+ 2.6 classic

Code:

Subtract(clip1,clip2)
WriteFileIf (last,  "log.log",  "LumaDifference(clip1, clip2)>0", "current_frame", """ ":" """, "AverageLuma")

Thanks mate, that works perfectly. I edited it a bit so I can copy/paste log to SelectEvery:

Code:

Subtract(clip1,clip2)
WriteFileIf (last,  "log.log",  "LumaDifference(clip1, clip2)>0", "current_frame", """ ", \" """)

AvS 2.60(2.6.0.6) & AvS+ 3.5 (r3106) produced identical logs, AvS+ was 20% faster.

I run comparison on stacked output with 4 steps (like in screenshot in the previous page), so, Prefetch(4) vs no Prefetch:
Detected discrepancies in 157 frames from 134237 frames, almost all of them in the top/right mask, in 18 frames those mask are ok but discrepancies are in the final step(bottom/left, but no visible differences).

Here is some examples of the bugged masks (it should be B/W with white numbers, last two digits shouldn't be visible), stacked original clip & one mask:

Now I need to run more tests to isolate the problem.

poisondeathray · 8th November 2020, 20:20

What format was source video ? Did you try threads=1 for LSmash ? Or other source filters to rule out some issue upstream ?

To be clear, was the issue only with Prefetch(4) ? Is no prefetch ok ? Or other values ?

I recall some discussion about source filter threads and seeking accuracy issues vs. host CPU threads , but I think that was for ffms2

VoodooFX · 9th November 2020, 13:28

Like I suspected it's something with Overlay, tested and same on AvS+ 3.4, 3.5.1, 3.6.0, 3.6.1.
Here is minimized and ready to run test scripts (extract to C:\) or preview included test results https://anonfiles.com/F7E0hdo2p0 or https://we.tl/t-J95N1CsfUz (7 days)

Isn't "threads=1" parameter for ffms2!? No-Prefetch is ok. I dunno working alternatives for LSMASH, and whatever source filter outputs it shouldn't bypass binarization of the frames.

"Bad gateway", expired perhaps?

StainlessS · 11th November 2020, 19:10

Same here, 502 Bad gateway. nginx.
Maybe that nginx thing is the block on your location for download, (cant remember what its called).
Can anybody launch successful download ?

EDIT: The Bad Gateway page is showing as Sweden in FlagFox. [dont know if relevant]

LSmash has threads=blah parameter too. But non frame accurate runs will account for differences between repeated tests, when prefetch is used

I repeated test with x64 version - I think the problem is lsmash threads=auto vs. threads=1 for x64. I think it' s similar to the aforementioned ffms2 threads bug with prefetch

EDIT - multiple consec runs can result in different results, even with source filter threads=1 . One run can show PSNR inf, but another something lower. Something else is going on...

It even occurs when source is encoded to I-frame UTVideo, and using AVISource instead; multiple runs can show different results when prefetch is used. So not source filter related

I tested threads=1 like you did, only with 32bit and got one frame bugged, so bug is there with threads=1 too. It makes less chance for bug to occur, 5mins is too short test for this condition.

Looking at those bugged masks I think it's something with buffer/memory, just a guess, I'm not into lower level programming.

Yes, it's almost "random", see my edits above . One run can be perfect, but the next a few frames off, the next perfect again. It's not source filter related

poisondeathray · 11th November 2020, 21:05

If you change the script to use mt_merge (and full range YUV masks , PC matrix if converting from RGB), 10/10 runs are the same with prefetch=4. So that suggests it is something with overlay and prefetch

Here is my minimalized script.

Code:

# Load VirtualDub, Press F2, go to frame 2-3-4 and back, refresh, step between frames left and right
# suddenly a garbage is seen
DynamicMask = BlankClip(1000, 128, 128, pixel_type="RGB32")
WhiteClip   = BlankClip(DynamicMask,color=$FFFFFF)
BlackClip   = BlankClip(DynamicMask,color=$000000)
BlackClip.Overlay(WhiteClip, Mask=BlackClip)
Prefetch(4)

Thank you for giving me the opportunity to work on it

Yep, Vdub2 reveals this bug on the first frames. Have fun with it.

pinterf · 12th November 2020, 12:24

Please check a (hopefully) fixed Avisynth build

VoodooFX · 26th November 2020, 18:43

There is some bug with high resolutions like 1920x1080 and AvsInpaint, if a mask is close to the left/right side then AvsInpaint hangs at start (no error).

Here is the bug simulator:

Code:

x=BlankClip(length=1000, width=1920, height=1080, color=$000000, pixel_type="YV12")

mask = BlankClip(x, length=1).Subtitle("Sample", text_color=$FFFFFF, x=8).Levels(180,1,181,0,255, coring=false)
# mask = BlankClip(x, length=1).Subtitle("Sample", text_color=$FFFFFF, x=519).Levels(180,1,181,0,255, coring=false) # Working position, moving the mask 1px to left("x=518") - hangs.

# x.InpaintLogo(mask, PreBlurSize=0.9, PostBlurSize=0.9)  # Droping the blur kernels to 0.9 - no hangs.
x.InpaintLogo(mask)

EDIT:
Bug should be fixed in AvsInpaint v1.3

thanks! but it's still in "Attachments Pending Approval", can you upload it else where?

It's approved now. As I don't read every post in every forum, if you have something needing approval, you can PM me if you like.

In your [@ VoodooFX] post #118 attachment [12s GIF sample], I earlier saw a white flash in bottom image part, it is now gone.
[maybe at end of repeated loop]
