HBVFWSource.dll - VFW sourcefilter for HighBitDepth YUV

[Reel.Deel]

Hi Chikuzen, since HBVFWSource is able to convert Vapoursynth's YUV42xP10/16 format into Dither's interleaved msb/lsb.
I was wondering if is possible to output the stacked msb/lsb also? It can be usefull for futher proccesing.

I tried converting the interleaved format to stacked msb/lsb manually, but I was unsuccessful. Also, I don't know if the results would be *correct*.

* Edit *

I don't know if this is also correct but did manage to output stacked msb/lsb using f3kdb. The thing is I don't want to deband .

HBVFWSource("16-bit test.vpy")

f3kdb(input_mode=2, input_depth=16, output_mode=1, output_depth=16)

it is possible for me to add stacked format output mode.
however, Since it will be slower than interleaved mode, I don't want to implement it not much.

HBVFWSource("16-bit test.vpy")
f3kdb(input_mode=2, input_depth=16, output_mode=1, output_depth=16)

f3kdb's manual says "If output_depth = 16, dither algorithm specified by dither_algo won't be applied."
thus, Your purpose is already achieved.

Yeah, I read that too, while no dithering is taking place isn't f3kdb still debanding? I'll read the documentation some more and see if I can come up with a conclusion.

If I find a way to turn interleaved into stacked manually I'll report back. Thanks anyways Chikuzen.

Set all thresholds/noise generation to 0 if you want to be super sure is does nothing. I did that myself some time ago.

Also this probably works:
turnleft().separatefields()
StackHorizontal(Selectodd(),Selecteven()).Turnright()

Thanks for the suggestion.

f3kdb(range=0, y=0, Cb=0, Cr=0, GrainY=0, grainC=0, blur_first=false, input_mode=2, input_depth=16, output_mode=1, output_depth=16)

I tried the same thing earlier. Strangely it doesn't work, I guess we must be doing something wrong.

Just checked. Works for me, both solutions give the same result.
edit: but f3kdb approach 2 times faster

[Reel.Deel]

I just double checked. You're correct, sorry. It only worked when the colorspace YUV420P16 but fails with YUV422P16.Turning interleaved YUV422P16 to Stacked 4:2:2 msb/lsb must be another ballgame.

I see, since you said this, I'm not sure if separatefields approach is correct in respect of chroma...

But I'll post another try anyway. Seems to be working:

SeparateColumns(2)
StackVertical(Selectodd(),Selecteven())

^avisynth 2.6 required

edit: it also ~30% faster than f3kdb

[Reel.Deel]

It works, thanks for your help Keiyakusha. Lesson learned.

[Chikuzen]

stacked output was implemented.

as I said, that is slower than interleaved mode.
but that may be faster than separatecolumns.

[Chikuzen]

update to 0.2.1

a bit faster stacked output.

[Reel.Deel]

Take a look at the bright side. HBVFWSource uses less resources than f3kdb and SeparateColumns.
Thanks again Chikuzen.

Vapoursynth script

import vapoursynth as vs
core = vs.Core(accept_lowercase=True)
core.std.LoadPlugin(path=r'C:\Vapoursynth\FFMS2\ffms2.dll')

# Source is 720p60 YUV420P8
src = core.ffms2.source(source=r"X:\MVI_1597.MOV")
src = core.resize.Spline(clip=src, format=vs.YUV420P16)
last = src

Results using HBVFWSource-0.2.1.

@Reel.Deel
HBVFWSource is not able to use on avisynth2.5x. (because I need YV16 for P210/P216)
thus, you should use SeparateColumns script on your comparison.
The cost of TurnLeft/Right is quite high.

[Reel.Deel]

@Chikuzen
Updated to SeparateColumns.

[Chikuzen]

sorry, I found a very stupid bug.

updated to 0.2.2

[Pat357]

I removed my post.
It was a false alarm : I made a mistake and I reported it as a bug.
My apologies for this.

[Pat357]

It seems that this plugin is broken.
My scripts that used to work (https://forum.doom9.org/showthread.p...76#post1594176), now give an error :

[avisynth @ 025a6e00] Cache: Filter returned invalid response to CACHE_GETCHILD_CACHE_MODE. 87825032
(K:\film\Vapoursynth\hbVFWSource_test.avs, line 6)
K:\film\Vapoursynth\hbVFWSource_test.avs: Unknown error occurred

I also tried the the posted scripts from reel.deel (see https://forum.doom9.org/showthread.p...78#post1594778), and got the same error.
If I just replace HBVFWSource by VSImport (VapourSource plugin) and replace last in the .vpy script by last.set_output(), everything works !

Any help on this issue would be more than welcome !!
