I'll PM soon you with a link to a sample clip.

Jeff, I had no problems at all with the clip you sent me. There is one AC3 audio stream and it is demuxed properly and plays fine.

a friend of mine using either build 2006 or 2007 said that if he used DG NV for a 2-pass encode and made the status of the 2nd pass "postponed" in megui then the 2nd pass wouldn't work when manually started, he would get "error" as the status like someone pointed out within the last 5 pages. He's away on holiday at the moment so i can't ask him anymore questions at the moment if you need more info.

Well, I do that all the time, and don't have any trouble.

Well I think I may have confirmed it. After frame 0, three of these look close enough to the same frames as expected, however the deinterlace=2 seems "out" by a frame.

SetMemoryMax(256)                    
LoadPlugin("C:\SOFTWARE\DGindex\DGMultiDecodeNV.dll")  
LoadPlugin("C:\SOFTWARE\DGindex\DGDecode.dll")  

dgi=DGMultiSource("G:\HDTV\AFL\compare\R3-HD-Q2-trimmed.dgi",deinterlace=0).AssumeTFF()
dgi=dgi.HEIGHT==1088 ? dgi.cropbottom(8) : dgi
dgi=dgi.Separatefields()
dgi=dgi.ScriptClip("""subtitle("dgi " + string(current_frame),size=25)""") 
dgi=dgi.Lanczos4Resize(dgi.width(),dgi.height()*2)

D2V=MPEG2Source("G:\HDTV\AFL\compare\R3-HD-Q2-trimmed.d2v",info=0,ipp=true,cpu=0).AssumeTFF() 
d2V=d2v.HEIGHT==1088 ? d2v.cropbottom(8) : d2v
d2v=d2v.Separatefields()
D2V=D2V.ScriptClip("""subtitle("D2V " + string(current_frame),size=25)""") 
D2V=D2V.Lanczos4Resize(D2V.width(),D2V.height()*2)

dgi2=DGMultiSource("G:\HDTV\AFL\compare\R3-HD-Q2-trimmed.dgi",deinterlace=2)
dgi2=dgi2.HEIGHT==1088 ? dgi2.cropbottom(8) : dgi2
dgi2=dgi2.ScriptClip("""subtitle("dgi2.deinterlace " + string(current_frame),size=25)""") 

D2V2=MPEG2Source("G:\HDTV\AFL\compare\R3-HD-Q2-trimmed.d2v",info=0,ipp=true,cpu=0).AssumeTFF() 
d2V2= d2v2.HEIGHT==1088 ? d2v2.cropbottom(8) : d2v2
D2V2=D2v2.Bob()
D2V2=D2V2.ScriptClip("""subtitle("D2V.bob " + string(current_frame),size=25)""") 

interleave(d2v,dgi,d2v2,dgi2)
SetPlanarLegacyAlignment(True)

Not sure where to upload the 20Mb sample, so here's a rapidshare link. Let me know if you want it uploaded elsewhere.

Based on information I received from Nvidia I believe the Nvidia chain introduces a frame delay when doing double-rate deinterlacing. There's naught I can do about it.

[tormento]

neuron2: could you please make a x64 compile to be used with avisynth x64?

[hydra3333]

OK, so I apply

trim(1,-999999)

to the NV double-rate deinterlaced clip and then it appears just like the others temporally. Thanks for checking. Love your tools !

Sorry if this is a dumb question, but where can I find the VP Engine speed in the NVidia specs in order to compare cards? I've been looking all over, and can't find it referenced anywhere. Is it normally given a different name? Is it the "core clock" speed?

If so, would the 220 GT be faster than the 240 GT for use with DGIndexNV (at least in theory... I know you can't test all these cards)? The 220 GT has a 625MHz core clock, while the 240 GT has a 550 MHz core clock.

[CruNcher]

You can't though the speed should be the same for every card 400 Mhz,what you can see is the actual Video Engine Load with Nvidia providing access to it through the NVAPI but this part is under NDA so not many applications implement that

GPU-Z, Everest and Msi Afterburner as well as EVGA Precision (same as Afterburner but from Evga both are based on Rivatuner) do currently



Here you can see Flash (also known as the beast) 10.1 RC in action on the in my case VP2(G92) Video Engine (the in action is meant sarcastically )

OK - thanks for checking. Maybe Windows was having a bad day. I'll keep investigating here.

It didn't take long for me to find the problem: PEBKAC. I had downloaded 2007, but 2006 was still installed. No issues with the file using 2007.

I like PICNIC -- problem in chair, not in code

another vote for a x64 version if possible now we have megui 64 as well

[colinhunt]

OK, so I made a boo-boo by not reading this thread before making a donation for the license. Turns out (as you all know) that CUDA drivers are not used when the PC is controlled via Remote Desktop connection. Unfortunately my dedicated number-crunching PC is located in a ventilated storage room and can only be accessed via Remote Desktop. Yeah, I'm SOL - especially as I can't get RemotelyAnywhere to work either. Does anyone know of any other work-arounds for this issue?

[GZZ]

You should try www.logmein.com (free) i works just fine with DGIndexNV.

Isn't that the same as RemotelyAnywhere?

edit: Same company, different product. I'll give it a shot. Thanks!

[Audionut]

I use teamviewer.

+1

Maybe I ask a stupid question, what is the benefit of a 64 bit DGIndexNV when it uses the GPU for Decoding, will frameservering be any faster because the program is 64 bit vs 32 bit ?

not sure if it would be faster, but it would allow us to use it with avisynth 64 bit and x264 64 bit. both those are faster
