CUDASynth

[hydra3333]

Any results with test5?

Yes, test5 yielded a pop-up on run #2 6 of 8. Hopefully I did it right.
I tend to find I may need to run the test a number of times since it seems to run successfully a few times in a row.

Running it again with nothing running in the background ...
Interestingly, something new.
1 of 8 success
2 of 8 returned only 1 frame (that's new, usually it is 0) and no pop-up
3 of 8 failed and no pop-up
4 to 8 success


editing the log and looking for 'frame=' I see

Thank you. After my afternoon swim I'll try to bring up the stuff you gave me.

[hydra3333]

It has nothing to do with cudasynth.

I had a pop up ("error creating decoder" ?) appear after reverting to the latest official release.
Unfortunately it disappears quickly, so I'll see if I can capture an image of it.
Funnily enough, all 8 encodes worked.
Realtime Task Manager performance numbers and graphs showed nowhere near full GPU memory consumption.

Sorry about that !!!!!!!!!!!!!!!!!!!!
I have no explanation other than it could well be my system.

edit:

Task Manager performance tab says dedicated GPU Memory never goes over 2.1/8 Gb[/i]

edit 2:
So, I reverted fully to the original vapoursynth folder with the official released DG stuff (i.e. without any newly copied DLLs and chance of a stuff up) and the say message popped up. Never noticed it before, not to say it never happened as I just popped the released DG stuff into the right place without any testing.
I wonder if it's to do with the nvidia driver which I updated a few weeks ago, or perhaps the latest Win11 updates which I installed recently ? Will install the latest nvidia driver and try that.
I have a terrible feeling, with no proof, that it's to do with my PC even though I install next to nothing and virus check everything frequently

[Rocky]

Interesting. Well, let's try to get to the bottom of it. I should have test results tomorrow.

One interesting thing is that in the released stuff if the failure to create occurred it did not exit the application. It's only the CUDASynth version that now does that. So, what if for some reason, some race condition or something, it tries to create the decoder twice. Then there would be the popup but things would proceed just fine after OK with the first creation. I'm in my nest right now and can't remember if the popup has a fast timeout. Most of the popups have timeouts. I think most of them are 5 seconds.

Thank you for the information and testing. I'm not thinking right now that it's only an issue with your system. It's good news that the problem is likely not due to the CUDASynth functionality or Vapoursynth API4.

[Rocky]

One possibility is that one of your streams changes video characteristics in mid-stream. If that is the case behavior will be undefined. The characteristics that matter are video type (AVC, HEVC, MPEG2, VC1), width, height, or chroma format.

Even if it is not a mid-stream change in one file, the DGI file may list multiple files that conflict with each other regarding the listed characteristics.

In both of these cases, the decoder gets killed and re-created. But the rest of DGSource() remains init'ed as for the initial characteristics, e.g., the frame size reported to Vapoursynth, the size of internal buffers, etc. DGSource() is simply not designed to support changes in the video characteristics incurred by a single decoding instance. I need to look at your test stuff to see if you are running into either of these scenarios. I don't know what your ffmpeg/pipe stuff is doing. The intended behavior is that every new encode should be done from a new decoding instance.

Let's see.

[Rocky]

I've ruled out format changes within or between your 8 test files. Moving on to recreate your test environment...

EDIT: I am unable to test your files as processed by your QSF script stuff (see following post).

[Rocky]

Ran into problems running your environment. The QSF video files are missing when DGIndexNV runs:

Code: Select all

D:\tmp\hydra3333\HDTV\DGtest>"!vapoursynth_root!\DGIndex\DGIndexNV.exe" -i "!QSF_VIDEO!" -e -h -o "!_DGI_FILE!"

D:\tmp\hydra3333\HDTV\DGtest>TYPE "!_DGI_LOG!"
The system cannot find the file specified.

It looks like the code in the bat file to create them is commented out. If I re-enable it, it wants to run a VB script, which is absent (no .vbs file anywhere), and I don't have VB installed anyway. There are no source files in the RESULTS folder.

How to proceed?

[Rocky]

Hold the presses! The following script fails with video hanging on the girl water skiing, but only for Vapoursynth.

Code: Select all

import vapoursynth as vs
from vapoursynth import core
core.std.LoadPlugin(path="D:/Don/Programming/C++/DGDecNV/DGDecodeNV/x64/Release/DGDecodeNV.dll")
video = core.dgdecodenv.DGSource(r'D:\tmp\hydra3333\HDTV\DGtest\TEST_SOURCE_VIDEOS\00_PostcardsFromMannum_sample-unprocessed_interlaced_CUT.dgi',deinterlace=2)
video.set_output()

Are you by any chance using deinterlace=2?

I will troubleshoot this, but I still need you to get me going on your test environment.

[Rocky]

I fixed the hang, so re-download test6. There's a chance that bug is causing your problems but I'm not sure, so please test it.

[hydra3333]

Oops, a poor assumption on my part on what files pre-existed or not.
OK, I popped some files *.qsf.mpg into the "RESULTS" folder in this share:
https://drive.google.com/drive/folders/ ... sp=sharing
The files are the same as the originals except having been fixed where possible via VideoReDo's QuickStreamFix.

If you place the *.qsf.mpg files in a folder "RESULTS" underneath the folder the script is in, the script should find them provided these variables are set to your satisfaction

Code: Select all

set "root=G:\HDTV\DGtest"

Set "C_source_TS_Folder=!root!\TEST_SOURCE_VIDEOS"
Set "C_done_TS_Folder=!root!\RESULTS"
Set "C_temp_path=!root!\SCRATCH"

The hacked up script uses this:

Code: Select all

set "QSF_VIDEO=%C_done_TS_Folder%\!source_filename!.qsf.!extension_mpeg2!"

to find the cleaned-up files and specify into dgindex etc.

Here's a typical test .vpy and it uses deinterlace=1 (2 not used in these tests).

Code: Select all

import vapoursynth as vs		# this allows use of constants eg vs.YUV420P8 
from vapoursynth import core	# actual vapoursynth core 
core.std.LoadPlugin(r'G:\HDTV\DGtest\Vapoursynth-x64\DGIndex\DGDecodeNV.dll') # do it like gonca https://forum.doom9.org/showthread.php?p=1877765#post1877765 
core.avs.LoadPlugin(r'G:\HDTV\DGtest\Vapoursynth-x64\DGIndex\DGDecodeNV.dll') # do it like gonca https://forum.doom9.org/showthread.php?p=1877765#post1877765 
before_video = core.dgdecodenv.DGSource( r'G:\HDTV\DGtest\RESULTS\00_PostcardsFromMannum_sample-unprocessed_interlaced_CUT.DGI', deinterlace=1, use_top_field=True, use_pf=False ) 
#after_video = core.dgdecodenv.DGSource( r'G:\HDTV\DGtest\RESULTS\00_PostcardsFromMannum_sample-unprocessed_interlaced_CUT.DGI', deinterlace=1, use_top_field=True, use_pf=False, dn_enable=3, dn_quality="best", dn_strength=0.06, dn_cstrength=0.06, dn_tthresh=75.0, dn_show=0, sh_enable=1, sh_strength=0.3 ) 
after_video = core.dgdecodenv.DGSource( r'G:\HDTV\DGtest\RESULTS\00_PostcardsFromMannum_sample-unprocessed_interlaced_CUT.DGI', deinterlace=1, use_top_field=True, use_pf=False ) 
after_video = core.avs.DGDenoise(after_video, strength=0.06, cstrength=0.06) 
#after_video = core.avs.DGSharpen( after_video, strength=0.3 ) 
stacked_video = core.std.StackVertical( [before_video, after_video] ) 
stacked_video.set_output() 

OK I'll try the updated test6.
Since I also get a popup in the current released binary (not a testX) - even though it somehow still encodes - I'm still wondering perhaps it's my PC.

[hydra3333]

Some results with the latest test6:

Code: Select all

Test Run 1: pop-up appeared once (item # unknown), encoded zero frames of it
Test Run 2: all completed successfully, no pop-up
Test Run 3: all completed successfully, no pop-up

Test Run 5: pop-up appeared once on item 7 of 8, encoded zero frames of it
Test Run 6: pop-up appeared once on item 2 of 8, encoded zero frames of it
Test Run 7: all completed successfully, no pop-up

edit: ran it once more with task manager "Performance" tab looking at GPU,
pop-up appeared once on item 1 of 8, encoded zero frames of it

Code: Select all

dedicated GPU memory 2.4/8.0 GB
shared GPU memory 1.2/16.0 GB
GPU memory 3.5/24.0 GB
utilization maxed at 94%

pop-up appeared once on item 5 of 8, encoded zero frames of it, similar gpu stats

[Rocky]

OK, it's not your system because it happened to me. Investigating...

[Rocky]

Please re-download test6 and re-test. It's working good for me.

[hydra3333]

Cool, success, no pop-ups or failed encodings. Thanks !

I ran the 8 encode batch, 10 times in sequence for both "new cudasynth way" and "old multi-line way".
Something I don't quite get with the latest test6 ... the speeds for "new cudasynth way" vs "old multi-line way" look close to the "new cudasynth way" when encoding ?
(I ran the encodings without anything else running in the background and without encoding audio, results below.)

Perhaps the source clips weren't large enough to show a significant difference, or the encoding chain is a levelling factor ?

(a) Results for "new cudasynth way" eg :

Code: Select all

after_video = core.dgdecodenv.DGSource( r'G:\HDTV\DGtest\RESULTS\00_PostcardsFromMannum_sample-unprocessed_interlaced_CUT.DGI', deinterlace=1, use_top_field=True, use_pf=False, dn_enable=1, dn_quality="good", dn_strength=0.06, dn_cstrength=0.06, dn_tthresh=75.0, dn_show=0, sh_enable=1, sh_strength=0.3 ) 
after_video.set_output()

Just in case the limiting/levelling factor was vspipe/ffmpeg/nvenc encoding speed, I re-ran the 8 encode batch, 10 times in sequence for both "new cudasynth way" and "old multi-line way", just using vspipe only with frames to null :

OK, vspipe-only results (c) and (d) appear to show a significant difference.

I suppose one could test frame sizes larger than 720x576 to see if the encoder chain is still the levelling factor then (One may guess that heavy filtering of sorts using cudasynth may yield most benefit, and comparison of cudasynth to to cpu-only filtering may be fairer in some way).
And, test on another newer nvidia card if one has one, i.e. better than an RTX2060 SUPER VENTUS OC.
Ah, fun for another day I guess.

Thank you.

[Rocky]

Thank goodness!

Yes, I think you are right about performance. I believe the relevant factors are the frame size [most important as the gain scales as O(size^2)], and the dilution by the extra stuff in your chain. You'll have an approximate 2500% increase in PCIe load for UHD versus SD! And another times-two for HBD. We could also think about connecting to NVEnc without coming back to the CPU, further reducing the PCIe load, and obviating the need for vspipe, etc. Finally, by keeping PCIe load to a minimum we have headroom to implement further parallelism, although the raw decode will always be limited by the one NVDec and NVEnc engines. Hmm, don't some GPUs have multiple engines?

When testing with the old way, you should also use the old DGSource(), because you have a 34% gain on the decode side even without using any integrated filters. That gain is coming from the CUDASynth framework.

What filters would you like to see added next? I'll probably make a formal release of DGDecNV pretty soon, maybe before adding more filters.

I'm surprised you didn't ask what the root cause was.

Listen up, m8. I'm so grateful to you for reporting this issue and supporting me with your testing and analyses. I also learned some stuff that will be useful for me. It was something of a dog's breakfast for a while there but now it's bonza. You're a definite ripsnorter, so throw a shrimp on the barbie!

[hydra3333]

I'm surprised you didn't ask what the root cause was.

I did wonder, and curiosity nearly got the better of me, however I had enough of those questions in the last 10 working years to choose not to bother you. Suspected you'd needed to brute force it with retries if the cause was not discernible, which is what I'd had to occasionally consider in the past just to get something going Then thought you'd get the better of it

Anyway, most thankful for your wonderful work ... I rely on it every day. Beaut !

A word to the wise, the advertising wallahs do ads about shrimps on a barbie ... us ordinary bogans chuck on steaks and lamb chops and chopped onions and sliced potatoes

[Rocky]

Suspected you'd needed to brute force it with retries if the cause was not discernible

Brilliant thinking. At first I just said let's retry up to 5 times but fortuitously I added a two-second sleep in the loop. Then using debug statements I saw that it never retried more than once. So I just put one sleep before the create decoder call. Then I noticed that the majority of the time it did work the first time without delay. We knew that from the sporadic nature of the popups, too. So now I do the first try without a delay and if it fails, I delay and try again. I do try 5 times and then do the popup if it continues failing, just so that we will have an indication if things go wonky. My theory is that CUVID needs some time to properly close and your processing stream comes fast and furious. Occasionally the close would not be finished. We don't have a good way to actually verify that but it's good enough for me.

Thanks for the rebuke about shrimp on the barbie. I guess that's for foo-foo people, not people like you and me.

Please don't forget to tell me if you are hot to trot on any additional filters. There's a Yank saying for you.

"It began as a common phrase people used to talk about someone who was more than ready for s*x. It began in the early 1900s and derived from American jive talk, drawing from the idea of a horse eager to get going."

[hydra3333]

Well, just a thought ... on something probably in the too hard basket and/or not worth one's while ...

A few things seem to depend on motion estimation like the venerable mvtools2 https://avisynth.org.ru/mvtools/mvtools2.html for example
(i) temporal denoising, which you mention above
(ii) motion interpolated framerate changing
(iii) and a "DepanStabilize" (useful only for the home videos market)

I vaguely recall a post somewhere about a part of the nv block being able to return motion vectors however you didn't seem to be altogether convinced, so maybe it's not possible or too hard or not worth the effort to try it.

If a motion compensated framerate changing using interpolated frames and/or a "DepanStabilize" is even possible, one wonders if there'd be a speed benefit or not. Don't know if nvidia provide something handy in a lib, who knows.

Nope is always a fine and well accepted answer

Dare I mention it may be possible garner a couple of bob from commercializing it (or may not) ?

[Rocky]

Yeah, I hear ya. I'll eventually get around to that.

[Rocky]

Here is test7:

* When opening and indexing a media file directly with DGSource(), by default streams are
now not demuxed. If you want to have them be demuxed while indexing, add an @ character to the
DGSource() filename, e.g., DGSource("file.ts@").

* The DGDecodeNV manual was brought fully up-to-date, and so the Notes.txt file was removed.
This build is now considered to be a release candidate for DGDecNV 252. Changes to DGIndexNV are
insignificant. Please give the new document some scrutiny and report any issues. Thank you.

Sherman for the document update.

[Rocky]

Oops, the 'show' option for DGDenoise() got missed in the document. Sherman will fix that and re-up it this afternoon. He's busy doing his math tutoring right now.

EDIT: manual was updated online.

Hello, a "quick" query. Similar to previous tests on VHS videos 0 to 7 in sequence, repeated with various settings.

Yes it's a poor test since it stacks filtered alongside unfiltered, with associated overheads.

Though I wonder, is that variation in fps to be expected ?
Perhaps the nature of the sources, or ffmpeg nvenc encoding takes longer due to less effective denoising ? Although, the first 2 lines in the ** test compared to the first 2 lines in the repeated test (in the same box) seem to render that unlikely.

Cheers

PS dn_enable options aren't described in the manual

Thanks for pointing out the missing dn_enable stuff, m8. I have fixed it. I'll try to answer your fps variation question tomorrow as I am tired after getting 252 out the door and helping Curly with his eac3to release. Plus I just ate a large ribeye and my brain is in a fog.

BTW, in the release, I omitted the AVX512 executable as it was identical to the AVX2 one. So nothing in the code could benefit from it, apparently.

BTW2, the next filter will be a full-featured DGTweak(). In case y'all forgot, I wrote the very first Tweak() filter way way back when.

No worries. We'll deserved break from it.

Sounds great. Will it support features like auto gain, auto balance? This filter here http://avisynth.nl/index.php/AutoAdjust is one of the better ones, but it's also a bit broken (no source code)
