I'll experiment with it today. Thank you for the ideas. Obviously a deterministic solution is preferred.

I just slipstreamed my latest version of this fix. Please run with this one and let me know if it ever hangs again. Thanks.

Thanks for your work 
Just out of curiosity, if my guess is roughly correct, according what you've said.
In the constructor (i was hesitating between creator/constructor, but constructeur seems more logical), you start a thread to handle all the CUDA things. This thread init things, and when done, wait for a getframe (and maybe other things). When this "CUDA thread" has finished its init and is waiting, you have to notify the constructor that it's finished and it can itself finish.
In the getframe, you trig an event to tell the "CUDA thread" that you've received a getframe.
So is it, roughly, something like this ?

Don't want to patronize or anything, just giving suggestion if needed, in case my guess is correct.
If not needed or don't want it, just ignore, absolutely no hard feelings.
My suggestion :
In that case, even if Getframe is called between the tiny interval, it shouldn't matter, the event was already trigged, there will just be no wait. Ajust according the number of dispatching jobs between both.
If not needed or don't want it, just ignore, absolutely no hard feelings.
My suggestion :
Code: Select all
constructor
{
Doing stuff
Creating E1 Event.
Starting "CUDA Thread"
// Waiting "CUDA Thread" finished
WaitForSingleEvent(E1)
Destroying E1 event
(will not be needed anymore, don't waste resources for nothing).
}
Destructor
{
Destroy E2 to E6
}
CUDA Thread
{
Doing Init Stuff
// Init is done, i'm ready, notify constructor
SetEvent(E1)
While whateever_exit_or_ending_filter_condition_is
{
WaitForMultipleEvent(E2,E3)
ResetEvent(E2)
ResetEvent(E3)
// Don't know what E3 is, don't care, it will follow the same idea than GetFrame
// Doing CUDA stuff
// Notify GetFrame 1rst part of CUDA Stuff is done
SetEvent(E4)
// Waiting GetFrame notifying its part is done
WaitForSingleEvent(E5)
ResetEvent(E5)
// Doing CUDA stuff
// Notify GetFrame 2nd and last part of CUDA Stuff is done
SetEvent(E6)
}
Doing Ending stuff
}
GetFrame
{
Do Things
// Notify CUDA it can do its stuff
SetEvent(E2)
// Waiting CUDA finishing part of its job.
WaitForSingleEvent(E4)
ResetEvent(E4)
Do things
// Notify CUDA it can do the 2nd part
SetEvent(E5)
// Waiting CUDA finishing part of its job.
WaitForSingleEvent(E6)
ResetEvent(E6)
Do things
}

OK.
Please advise the results of testing my last slipstream.

I've begin to use it. No issue but no big project also immediately (just a very few files). I'll report after a longer use, so may take a little while.

I've worked on several project with a lot more of files recently, and so far, so good.
So, it seems that the issue is indeed probably solved.

Thank you, my friend, for the update, and for helping me to improve DGDecNV. In honor of your contributions, I have placed you in my Distinguished Member group.

Happened again... 
But... DGIndexNV is for now second in suspect list, another is the first suspect.
Nevertheless, i would like to provide the ProcessExplorer stack dump when next hang, like last time.
With it, will you be able, in the first time, just checking if hang occured within DGIndexNV or not ?
Situation is not the same as before, this time, DGIndexNV is not the only one filter used.

It looks like Filtres_JPSDR.vdf is getting stuck. What is that? Is it a filter you are running in VirtualDub?
Re: [RESOLVED] Sometimes VirtualDub hangs with no error message
Posted: Mon Feb 20, 2017 2:54 am
Ok, thanks for the information, it's some of my filters.
As i've said, this time it was different from last time, DGIndexNV wasn't alone, and wasn't also the first in the suspect list.
And now, we know it's not it, so, it's not on your.
I absolutely don't understand the stack information i've provided you. Can you tell me what information told you which process is stuck ? It may help me in future cases.

Nothing magic about it. The first stack trace had a wait at the top, so it was stuck waiting for something. Moving down the stack (down the listing) you see it passing through OS kernel calls and then you see your filter which initiated the call chain that led to the wait. The wait was initiated in the function VirtualdubFilterModuleInit2() of your filter.

NeatVideo answer :
Even worse, i have no idea when VirtualdubFilterModuleInit2 is called...
And, if my guess would be within the Init of my plugin, it makes no sense, as i don't call any wait function in my init... I've hit a total mystery here...
Well, apparently, i'll have to learn to live with it...
Not good...Thank you for the minidump. We took a quick look into it and so far the situation is not very clear.
Neat Video is involved, CUDA is involved, other plug-ins are also involved into that process.

Please provide your filter source code, so we can try to find the problem. You don't have to live with mysteries.
Your filter .vdf exports VirtualdubFilterModuleInit2 (). It is called by VirtualDub when the filter is instantiated. Your code would be helpful.

You loaded an avs script in VirtualDub and then added VirtualDub filters? What was the script and what filters? Thanks. I would like to recreate your scenario.

Thanks for trying this, even knowing that NV is not causing it...
You can get also my avisynth plugins on my github, i'm using the "all in one plugin" for avisynth, the one called "plugin_jpsdr".
Script :
DGI file is created from a Blu-Ray.
VDub : Input/Output colors are set to YV24, compression is UT Video 17.4.0 YUV444 BT709.
Internal VDub filters :
RGBConvert BT709
NeatVideo 4.5
RGBConvert BT709 , output YV24.
AddBorder (Top/Bottom 20).
alias BT601.
VDub version : VDub build 35570
Full x64 chain. avs+ r2420 for avisynth.
I think that's all...
And time to sleep, i've caught a bad cold...
