DGAVCDecNV 1.0.13: GPU decoding on Nvidia

[Guest]

The fix is released at my web site. Thank you for pointing it out.

[Atak_Snajpera]

Another bug (affects both DGAVCDecNV and DGAVCDec)
is DGAVCDec fixed as well?

[Guest]

I'm doing it now. Patience please.

[Sagekilla]

neuron2: I have a feature request. Would it be possible to merge DGAVCIndex and DGAVCIndexNV into one program, and offer a license to enable GPU decoding? I could imagine that for AVCSource() you could call it like so: AVCSource("file.dga",GPU=true,deinterlace=true). I'd think that you could somehow just have it check for a license key before it allows GPU decoding.

Just a thought :) It would be nice to see but if it's not possible then no worries.

[Guest]

I could probably do it, but it's not high on the list of priorities compared to VC1 support, MPEG integration, and MKV/MOV support. Thanks for the suggestion.

[lucassp]

I could probably do it, but it's not high on the list of priorities compared to VC1 support, MPEG integration, and MKV/MOV support. Thanks for the suggestion.

There's a very limited amount of GPUs supporting full VC-1 Decoding, so you could put it on a lower priority.

[Comatose]

Will MKV/MOV support be in DGAVCIndex as well?

[ultratoto14]

Test it for the first time, it's impressive. I think about a new feature. I think that cuda have optimized functions to resize the image. Is there a possibility to serve already resized frames ? As 1920x1080 -> 1280x720 is CPU consuming.

Great job.

[turbojet]

any news on the radmin/windows rdp causing encodes to hang?
you'll have another customer if this issue is resolved.

[drelin]

Just a question.

I've installed the CUDA driver, and now the Hardware accelration on POWERDVD (7.3) not run. If I desactive the PureVideo Acceleration on POWERDVD, the display is correct (but I lost the Hardware accelration) and the pureVideo activated no video displayed (black sreen with error message and video run).

Anybody have a solution for that ?


Thank and sorry for my bad english.

[drelin]

OK

I 've found the solution.
Just a update of POWERDVD is needed for DXVA works correctly.

[Guest]

Will MKV/MOV support be in DGAVCIndex as well? Yes, the two will track. The only difference will be use of the GPU for decoding.

So, I get approx. 0.85fps speedup.

If the full movie has 200000 frames, using DGAVCDecodeNV will finish encoding about 1h12min earlier.

you'll have another customer if this issue is resolved. Please explain in detail what I need to do to duplicate this issue. What environment, what software, what operations.

[lucassp]

I'll ask Nvidia if is possible.

It should work, but you have to do "real" CUDA programming for that.

http://forums.nvidia.com/index.php?showtopic=60853

[Guest]

I meant possible with the nvcuvid.dll interface.

[turbojet]

neuron2 for the radmin\microsoft rdp issue. You might have rdp (remote desktop protocol) installed, check for computer properties, advanced settings, remote, and tick allow if it isnt already.Otherwise you'll need to install radmin (http://www.radmin.com/) on a dgavcindexnv capable computer. Start an encode, and if you either login or logout from either service the encoder hangs.

[Guest]

Do I need to have two machines and login remotely? If you want this looked at you're going to have to spoon feed me.

Give me an exact step by step of what to install and do.

[Quark.Fusion]

Donald, what about to make free version with limit to half of source framerate for example? It will not be suited for realtime decoding, but provide good demo of technology. Also with heavy encoding settings I'm don't think that 1-5% speedup is worth 15$.

[Guest]

Also with heavy encoding settings I'm don't think that 1-5% speedup is worth 15$. As I have said many times, the speedup is not the only reason for this software to exist. If you don't think it offers you anything, then don't buy it.

[jeffy]

@Quark.Fusion: When you encounter a stream badly decoded by anything but DGAVCDecNV, then you might find the worthiness in it.

[turbojet]

neuron2 with radmin you can do it on one box, radmin will crash after a few seconds after you login but it will halt the encoding

[drelin]

I've a problem.
DGAVCDecNVindex run correctly, and I can save the projet.
But I can load the avs file in MEGUI (the soft close immediatly) and when i want to test directly with X264 command line I see teh error message :
"RAWYUV imput requires a resolution" ??.

If you have any suggestion for a solution ?

THX.

I believe the problem with MeGUI has already been explained earlier in the thread.

Post your script though, there's probably something missing in it.

[Guest]

MeGUI situation is documented.

For the x264 CLI, post your script and your x264 command line.

[Guest]

neuron2 with radmin you can do it on one box, radmin will crash after a few seconds after you login but it will halt the encoding Do I have to install the server or the viewer or both? Assuming I install it, how do I login to it in the manner you are talking about?

I did ask for a step-by-step. I just don't have time to do experiments to figure things out.

EDIT: OK, I have remote desktop working. Now, what do I do exactly? Do I connect and start the encode and then disconnect? Do I start it locally and then connect from remote? You gotta tell me what to do.

EDIT 2: I remote connected and tried to start DGAVCIndexNV. I get a CUDA init failure 100. I have written to Nvidia about it. Probably something related to the DX/D3D init.

[Guest]

Nvidia responds as follows:

That's unfortunately an OS limitation because the display driver gets unloaded with remote desktop operation. The exception would be VNC, which is more gpu-friendly in that regard.

The workaround, then, is TightVNC as previously mentioned.

[turbojet]

Bummer. VNC is ok software, I like that its open and free. But it really reduces my ability to work as I mentioned before with sluggish performance and random dropouts.
Thanks for checking with nvidia. I'll go see if radmin can work around this.

[bond]

I can use the "beer money" to buy the MP4 spec I need. mp4 specs are freely available:

[Guest]

Not quite. Try getting -14 and -15.

But don't worry, I have them now.

[ultratoto14]

I use x264 command line as meGui crashes every time. I usually use staxrip but it crashes too. What are the recommended front-end for X264 and XVID encoding with DGAVCIndexNV ?

[Guest]

I use MeGUI to generate the command line and then copy it out to run with CLI.

This doesn't work with two pass profiles.

[rebkell]

This doesn't work with two pass profiles.

It does if you have one in history. You just have to substitute the current input and output source and destination.

[Guest]

@rebkell

What do you mean by "have one in history"? Can you please give us a step-by-step? Thanks!

@all

I just installed the Nvidia driver 178.13 which came out within the last few days and my High Profile, Level 5.1 streams now decode properly. The problem with non-detection of the CUDA device requiring a reboot is also believed to be fixed by this driver version.

Well, it's actually in the log tab, just run a two pass job(really short one if you like) with the parameters you want for the encode.

After it's through, go to the Log tab and expand the Job(s) one of the lines will be very long and it's the x264 encode line, just right click it and Edit Text->Node and it will open the command line for the first pass in notepad. It will contain the exact command used by x264 for the encode. Do the same for the second pass to get the final pass command line.

[Guest]

[rebkell]

Not sure how to do it if it crashes, here's a typical two pass command line, I'm using the old profile of Xbox-PS3, with a few tweaks on the keyint and min-keyint stuff. The bitrate is calculated from the number of frames times the bitrate to figure out the final size.

"C:\Program Files\megui\tools\x264\x264.910.modified.exe" --pass 1 --bitrate 3400 --stats "G:\Junk\Bones\Bones0405.stats" --level 4.1 --keyint 60 --min-keyint 1 --bframes 3 --direct auto --subme 1 --analyse none --ipratio 1.1 --pbratio 1.1 --vbv-bufsize 9000 --vbv-maxrate 24000 --qcomp 0.5 --me dia --merange 12 --threads auto --thread-input --progress --no-psnr --no-ssim --output NUL "G:\Junk\Bones\Bones0405.avs"

Don't know if it helps, there's not a significant difference between the first pass and the 2nd pass, you can check it out.

[xopowo]

I don't know if I'm the only one experiencing this, but if I have a script that looks like this:

AVCSource("1.dga", deinterlace=true) ++ AVCSource("2.dga", deinterlace=true)

Then when virtualdubmod gets to the second AVCSource, it crashes with some error that says it can't be "read."

If I run them seperately, then both of them work fine. Also, once an AVS is loaded into vdubmod, and then if one closes that file, and tries to load another one (without physically closing the program), vdubmod crashes again based on the same type of message. Something is getting hung up is my guess?

[Guest]

I can't duplicate any of that. What version are you using?

[xopowo]

AVISynth 2.5.7 and v1.0.1 of the program.

[xopowo]

Also, two more questions:

I guess only one thread can be addressed at one time? I thought this was fixed? Neither vdub can be accessed with more than one instance at a time, nor can x264 from CLI.

Additionally, I know that you (Donald) had mentioned building a ts cutter for h264 since there isn't a good one out there. If this is still something that you intend to pursue, is it possible that it could use the purevideo CUDA things as well (as opposed to DirectShow and/or haali)?

[Guest]

I'm sorry but multi-instance is working fine and you are the only person reporting an issue. Let me think about it and then send you a debugging build to try to find out what is happening for you. In the meantime what is the exact error you get when you load the script the second time?

An intitial version of a cutter would use libavcodec for broadest compatibility, but don't look for this to arrive any time soon.

That is what happens when I try to open two instances of vdubmod. Also, when I run x264.exe from CLI, the first one runs, the second one starts to go, then just stops (it doesn't give an error); it just doesn't do anything.

[ultratoto14]

I search in windows error log to see if the problem with meGui is the same than Staxrip. I've got two different cases :

Sorry for the language, I'm French. This is strange that the DGAVCDecodeNV.dll installed is not 1.0.0.0 but 1.0.1.0.

I tried to create multiple instances of the DGAVCDecodeNV and have no problem with two virtualdubmod.

Tell me if you want me to test something.

when I run x264.exe from CLI, the first one runs, the second one starts to go, then just stops (it doesn't give an error); it just doesn't do anything. I'm supposed to guess what your CLI commands were???

Also, provide a link to a stream sample that I can use to duplicate this.
