Support forum for DG Tools

DJATOM

Also noticed some glitches with show=True

DJATOM

Downgraded to 391.35 and it fixed "exit on refresh" issue. But I found another similar problem. with show=True I can load the video, but on scrolling (backward/forward) application is closing on it's own. Is that something on my side or with dgtools?

DJATOM

Reinstalled entire system so yeah, the latest driver from Nvidia. Okay, will downgrade to something order then. I knew that the latest update is evil

About crashdumps... Application is just exiting on refresh, no error messages or so. Where I can retrieve such logs?

DJATOM

My VapourSynth Editor crashes on refreshing, but idk if that's on my side (I'm using self-built R44-test1 from github) or DGDecoder's fault, so we'll wait for another reports. My workflow is depend on last changes, so I need to use it. And downgrading is sort of hassle, so I'd like to wait for repor...

Thx, my notebook's gt555m is quite oldschool hardware now.
I'll stick with installed driver then.

ConvertBits(8) just drops the Least significant bit, so you need to add dither=0 or 1, whatever method you want to use there.

DJATOM

fmtc can do bits conversion. If you don't want to convert with fmtc, internal resizers can perform bits conversion as well:

Code: Select all

from vapoursynth import core, YUV420P16
...
clip = core.resize.Point(clip, format=YUV420P16)

DJATOM

Also checked without up-conversion to 16 bits, that works as intended. LwlibavVideoSource("D:\ACCEL_WORLD_INFINITE_BURST_UHD\BDMV\STREAM\00004.m2ts") ConvertFromDoubleWidth(bits=10) z_ConvertFormat(pixel_type="RGBPS",colorspace_op="2020ncl:st2084:2020:l=>rgb:linear:2020:l", dither_type="none") DGRei...

DJATOM

Code: Select all

LwlibavVideoSource("D:\ACCEL_WORLD_INFINITE_BURST_UHD\BDMV\STREAM\00004.m2ts")
ConvertFromDoubleWidth(bits=10)
ConvertBits(16)

That way I get native 16 bit video (checked with ConvertBits(8,dither=0) and ConvertToStacked(), both produce valid output for me.

DJATOM

So I'm trying to test the DGTonemap plugin without DGSource (as I don't have a HEVC decoding GPU). I'm not sure what the plugin expects as input. As 16 bit source, it returns double the height but a proper image at the top. This is my script (cropping the bottom) LSMASHVideoSource("source.mp4", sta...

Just wondering, since the current version of DGTonemap aims at Avisynth+, do you plan to create a version for Avisynth 2.6 too?

Cu Selur

2.6 one requires stacked or interleaved hack to work with HBD video. Not sure if avsresize support it.

DJATOM

- Make everything work as mtmode 2 in AVS+ :) MT_NICE_FILTER will be better I think ;) As I understood from explanations and filter examples, programmer must care about memory allocations at getframe requests, not at the filter constructor. Mt mode 2 will care about safe memory allocation if filter...

Code: Select all

@echo off
for %%m in (%*) do (
	C:\encoder\dgdecnv\DGIndexNV -i %%m -o "%%~nm.dgi" -h 
	echo Indexed "%%~nxm".
)
pause

Change executable path to your own and save as "batch_dgindexNV.bat".
Just drag&drop your files onto that batch and it will index your files.

DJATOM

As I said earlier, I need that to know where IDR frames placed, than I can replace that GOP from fresh encode (my use case is fine-tuned filtering on fades, banding removal, custom anti-aliasing and other scene-like optimisations). So I take into account where IDRs placed and pad it with few frames ...

DJATOM

Nope, I meant *.264 files. I don't need "valid" playback, just allowing to index is fine. DGDecNV can index 10-bit .264 files (the decoding is broken though). When trying to index with DGDecIM I'm get --------------------------- Error --------------------------- 10-bit encodings not supported! -----...

DJATOM

I know that DGDecIM does not support 10 bit decoding, but I use .dgi files for finding IDRs and "fixing" bad parts in already encoded files. DGDecNV can index 10-bit encodes, but recently my GTX 750's Fan died (I bought new one on Alliexpress and waiting for delivery), so now I'm on iGPU and can't i...

DJATOM

I'm using Avs+ x64, my filtering chain works faster with it.
