This time I tested the DGAVC-Versions on an AVC-FullHD-Source.
Now I get 36 fps with CPU+GPU and just 18 fps with CPU only.

Looks like the DGMPG GPU is slower than the CPU like squid_80 said. I'm glad that the AVC-Version isn't as the MP-Version

I'm still not satisfied with that. Can yo do an experiment for me please?

Load the source into DGMPGDecNV. Set Video/Disable display and then hit F5. Wait for a while and report the FPS from the info display.

Here is beta 11. It adds some fixes for CUDA context creation that may explain some failures. It also contains experimental support for multinstance support. Please read the Readme.txt file carefully if you want to experiment with multiple instance support.

Done it, I got ~60 fps with that

So there is no way to attribute the slow-down to the decoding.

You don't think 60fps is a bit slow for simple MPEG2 decoding?

You have to remeber that the Cuda driver can only use part of your video card to decode video. I got a GTX 260 and get simular result on decoding, so it is as fast at it can go with the current driver. But getting 60 fps on 2 pass encoding will also require some serious CPU power.

you're being assumptive.
sure I've got a quad-core processor,
but i can get >300 fps with x264 using dgmpgdec as my source plugin for some 640x480 material.

For HD it's not terrible. Anyway that's not the point. I cannot see how that rate can bottle neck the encode to 4 fps.

Which is hardly comparable since they are getting 60fps on HD content. I'd say that going up almost 7 times in resolution and the speed only dropping to 1/5th of what you get is quite good. That seems to scale quite well. If you can get more than 60fps on HD content using the software decoder then you would have a point.

I tested the multiple instance and it seems to work. But I did some 'extreme' testing. I created *.dgm file and then executed the following very basic avs script:

Quote:

LoadPlugin("D:\DGMultiDecodeNV.dll")
DGMultiSource("d:\Encoding\AeonFlux\Video.dgm", resize_w=1280, resize_h=720)

I started the *.avs script in Media player classic and then executed it (each time opening a new media player classic) and it seems on the ~5th time (sometimes more) it crash with the following error:

Failed to create video decoder (100).

But then again its pretty 'extreme' to have the movie play like 5 times at once. But other then that, it seems to run just fine, it also seems more 'responsive' then before, but that might just be me... Great work.

Thank you for your test results, GZZ. The number of instances is limited by the amount of memory on your video card. I only get 4 instances so be happy.

It should be a bit more responsive as the server architecture requires more time in the Windows kernel.

But some GUIs have a problem with it and I don't know why at this time. I'm never going to compile/debug MEGUI, so...

It's a useful option to have so I'll continue to include it, but I'll always support the server too.

what kind of problems. I dont have any issue using the AVS script or parsing it for information (framerate, resoulution etc). It works just fine. In my own GUI I can have a encoding going (using x264) and at the same time I can queue a new avs script for encoding. Thats why I like the multiple instance. Basicly because I can encode one movie and then parse another avs file for information (and queue it) without killing the encoding.

So for me having the possibility to have 2 instance at the same time should be enough.

I guess you kept the old DGSource for backward compatible, as I dont see the point when you have multiple instance avaliable or do you plan to just 'update' the DGSource with DGMultisource and then kill DGMultisource so you dont have 2 DLL to maintain?

That's very interesting. What version of MEGUI?

Also, does it work with HCEnc 0.24 for you?

I'll support both until I resolve the problem I'm having with some GUIs.

Not using MEGUI, I created my own GUI(not out in public), so dont know about MEGUI...

havent tested HCEnc as I'm not doing much MPEG2 (DVD) anymore.
I got a RB-builder licens, so I could properly test it with RB-builder and report back..

I'm liking the new DGMultiSource. Not so much because I use multiple instances but because I always forget to start the CUDA server before firing my custom batch conversion program. Or megui kills it on exit when using it for it's analysis tool only.

Great work!!!

Guest · 19th October 2009, 15:45

Jeff, is it working for you with MEGUI? If so, which version?

Well I don't use it in megui, megui's analysis tool never did like it as a source, instant error. I'm forced to use a d2v source with megui's analysis tool. Once I use it to figure out film/interlacing, top/bottom field etc, I then use your nv frame server to feed the 64 bit x264 and batch convert a whole series.

shon3i · 21st October 2009, 11:27

I use last possible build of MeGUI and DGMultiSource work fine, i sucessfuly encoded two movies for now. Even i sucees with CEE SP2 encoder which is impossible with DGSource and 2-pass.

Guest · 21st October 2009, 14:26

Can you please tell me where to get that specific version of MEGUI?
