It works in plain DGDecNV, however there are few duplicated frames (hard telecined?) which cause some jerkyness, but no blended frames in DGDecNV.

DGDecodeNV() and DGDecodeIM(engine=1) should act the same. I will investigate it.

What driver are you referring to? I just tried engine=0 and I get the same crash. I assume there is something that needs to be installed.

I'm talking about the Intel graphics driver. If you have an iGPU in your processor and you run Nvidia as your primary, you can still access QuickSync, but you have to enable the Intel GPU in the bios and then install the Intel driver as secondary. Then you will have both QuickSync and CUVID. I am still investigating what the situation is for Intel Media SDK in SW mode on a processor without an iGPU.

Can you try installing the Intel Media SDK 2014 and let me know if that changes anything? There is this thing called a "mfx dispatcher" that calls the HW or the SW DLL. It seems the dispatcher is in the SDK. I'm just learning about this stuff along with you guys.

Also, can you try opening an AVC file with dgmvcsource() using SW mode (hw=1)?

Is there another place where I can download this without registration?

Tried the latest version with hw=1 and it works. Used the sample that was included in the earlier betas.

It's not a big deal. If you want to be on the bleeding edge, you sometimes need to do the needful.

Nevertheless, you're right, it seems a bit much to require end users to install an SDK.

That changes things in a very positive way.

I will release a beta later today or tomorrow that allows you to force SW mode, and should get things working for you.

Thank you for the important test results!

That switch definition seems quite counter-intuitive, isn't it?

I'd expect that forcing software mode should be activated by either hw=0 or sw=1...

The documentation explains that "hw" is an integer offering various choices and not a boolean. "hw" is renamed as "engine" for DGDecIM, and if you understand it that way I'm sure the confusion will dissolve away.

Here is beta 2 with expanded engine options. You can force SW for Intel, for example.

@Reel.Deel

This should fix your issue. I expect it to work either with Intel auto or Intel SW in your system. Please advise your results.

EDIT: Please use beta 3 and make sure you have libmfxsw32.dll co-located with dgdecodeim.dll.

I assume I can test this software by using a computer with Nvidia card to index using DGDecNV and then transfer that index file to a laptop without a Nvidia card to test using iGPU?

That will work as long as the paths in the DGI file are correct after moving to the laptop. You can edit the DGI file as needed or deselect 'use full paths' when you make the index file.

This will be moot soon as I am working on the stand-alone indexer.

engine=2 instantly crashes VirtualDub when I try it on the files I previously tested with. 0, 1 and 3 work okay.

Guest · 17th February 2014, 19:26

OK, thanks, checking...

Guest · 17th February 2014, 19:27

engine=2 works fine for me. Do you have the libmfxsw32.dll in the same place as dgdecodeim.dll?

I have added the libmfxsw32.dll to the ZIP and revised the Notes to mention it. If this turns out to be the reason for your crash I will fix up the error checking to be a little more helpful.

Guest · 17th February 2014, 19:37

OK, my bad...

I have to add the code to find libmfxsw32 as it is in DGMVCSource. For now, put it in the system dir and I will release a fixed beta.

Thanks for pointing this out.

I didn't have it. I wasn't aware that there was any requirement for an extra file. I have subsequently added it into C:\HDTV Tools\DGDecIM\ where DGDecodeIM.dll is, but the crash is the same.

Here's the crashinfo from VD.

So, that's C:\Windows\SysWOW64 on a x64 system... Works now.

Guest · 17th February 2014, 19:48

Here is beta 3 with the correct dll loading code. Now the libmfxsw32.dll can be put with dgdecodeim.dll and you don't need to put it in the system directory.

http://neuron2.net/misc/dgdecodeim_b3.zip

Thanks again for your test results.

Stereodude · 17th February 2014, 19:50

For whatever it's worth, the Intel SW engine has all the same problems (lockup stepping backward and returning at least part of the the video offset by 1 frame) as the HW engine that I detailed in this post.

Thanks. I'll look into it.
