HBVFWSource.dll - VFW sourcefilter for HighBitDepth YUV

[Chikuzen]

I wrote a small plugin

HBVFWSource-0.2.2.dll



enjoy!

EDIT:
2012/10/12
updated to 0.2.2

Awesome work!
That's exactly what I am waiting for!

Hi. Thanks for this plugin, but I have some problems:
HBVFWSource-0.1.0.dll
HBVFWSource-0.1.1.dll

Source is h264 Hi10P. VS produces output as shown in console window. I can't open 1920x1080 video at all - access violation.

P.S. Had hard time uploading images. It seems some hostings don't like doom9 anymore and block links coming from it...

The plugin worked for me but I also I had the same problems when I cropped in the vpy script.

Error 1

Avisynth read error:
Avisynth access violation at 0x00002023 in c:\HBVFWSource.dll,
attempting to read from 0x04419000

Error 2

Avisynth read error:
Avisynth access violation at 0x00002023 in c:\HBVFWSource.dll,
attempting to read from 0x04428000

Also when I crop, at the top of the video I see a green line a couple of pixels in height but in full length.

[Chikuzen]

update to 0.1.2

about access violation, I can't reproduce. please give me the sample and .vpy.

about green line, I noticed that, too.
When P016/P010 is read, V-plane will shift under one line.
Although I reread the code, the cause is not known yet

With HBVFWSource v0.1.2 I still get access violation 0x00001FB0 in HBVFWSource.dll.

VPY: test11_10b.vpy

import vapoursynth as vs
import sys
core = vs.Core(accept_lowercase=True)
core.std.LoadPlugin(r'k:\programs\ffms2-r725-icl\ffms2.dll')
ret = core.ffms2.Source(r"k:\film\10bit\Madoka_opening_10-bit_1080p.mkv")
last = ret

This test11_10b.vpy plays as 1920x1080 H264 Hi10P video in MPC-HC (with Madvr)

AVS :

LoadPlugin("k:\programs\AviSynth 2.5\special filters\flash3kyuu_deband_1.5.1_x86\flash3kyuu_deband.dll")
LoadPlugin("k:\programs\AviSynth 2.5\special filters\HighBitDepth_VFWSource-0.1.2\HBVFWSource.dll")
# LoadPlugin("")
HBVFWSource("k:\film\Vapoursynth\test11_10b.vpy")
f3kdb_dither(stacked=false, input_depth=10)
info()

What Am I doing wrong ?

Im using AVISynth v2.6.0.3 with the latest "Seth" MT version .DLL.

[Chikuzen]

ok, reproduced and (maybe) fixed.
I need some more test.
please wait a little.

So I think that the access violation is only happening when the video is not mod16.

I loaded my canon dslr video without cropping (1920,1088) and it worked.

I also had another dvd file that was letterboxed and the cropping problem that I had earlier was also solved by cropping to mod16 dimensions.

Unfortunately the green bar is still present.

* Edit*

Too slow, seems Chikuzen might of figured it out.

[Chikuzen]

update.
please try v0.1.3

[Reel.Deel]

Quickly tried with 1080p file and cropping to non mod16. They both work.
Also, no more green bar. Thanks Chikuzen.

Can't test anymore, gotta get to work.

[Keiyakusha]

Yes, seems to be working now. Thanks!

If someone's wondering why AvsPmod shows 'YV12' on the status bar, that's a bug and will be fixed.

Thanks Chikuzen!

From what I can see, AVSPmod simply does not support the new 2.6 interface (AVISYNTH_INTERFACE_VERSION 5). I would hardly call that a bug, rather a limited feature set.

Let's say 'it will be improved' then

@Chikuzen, great stuff! Would you be willing to open source this plugin and vsavsreader?

You can at least check readme.txt before asking.

He has already opened their sources.

Hi Chikuzen, just out of curiosity, what was causing the access violation problems?

I was mistaken in calculation of width of U/V plane.
I'm wondering why 0.1.2 was working depending on some case
