Intel QuickSync Decoder - HW accelerated FFDShow decoder with video processing

[egur]

I read the white paper on Optimus (Nvidia's switchable graphics solution). It's not 100% clear whether they disable the iGPU calls when the dGPU is active. The notion of the white paper is that it does. So it may NOT expose the existence of the iGPU to your application.
The proper behavior would be (for your app):
- Adapter #1 (main) NV620m
- Adapter #2 (secondary) HD 4000

If it exposes only the first adapter in D3D11, then there's nothing to do.

I don't have an Optimus system available for testing.

To check this, I'll prepare a version that will open a message box with this information. Wait a day or two, I'm in the middle of something else.

Eric, are you part of the Intel team working with the Handbrake folks on the new open source Media SDK? Handbrake forum reports Intel has been quite helpful in the effort so far.

[egur]

No, I'm doing this on my own time nowadays, as a hobby of sorts. I belong to a completely different division.
My position is enabling and supporting OEMs on CPU related issues/questions.

Version 0.42 is out with the following changes:
* Direct3D11 playback (decode + video processing) on Windows 8. Windows 8 allows D3D11 to play video without a display connected to the accelerating GPU.
* Fixed a minor bug in the deinterlacer.
* Fixed an issue with H264 handling of fragmented streams (TV streams with some splitters)
* Updated MSDK headers and dispatch library to Intel Media SDK 2013.
* FFDShow: r4508

Downloads
* For the latest cutting edge FFDShow builds download my builds Intel QuickSync Decoder SourceForge home page
* FFDShow-tryout site
* LAV Splitter builds

[Superb]

Great work Eric!

That is exactly what i tested but it doesn't work. For information i use a soft called Mirillis Action! to record my mix. It can use the igpu to record the video window on the secondary display although the soft is using the dGPU (and Cuvid with Lav)

I gonna test the new version to see what happens

[itsonlyjustincase]

I have just tested. My soft doesn't work if i don't force the nvidia to be used. But then i guess i won't use igpu as the dgpu has been forced. The QS works fine with others

Thanks for your work tough

I've confirmed that several dGPU drivers in switchable graphics will block the secondary (Intel/iGPU) device.
This means no hybrid/headless support is possible.
Maybe new versions of the Nvidia/AMD drivers will provide this option.
Desktops don't have these issues.

[hoborg]

BTW, i tryed to run Intel HD 2000 + AMD 7750 (primary) together on my desktop few weeks ago on Win7 x64 and they fight each other. This mean internet browser was crashing (flash module), Direct show was crashing (while adding video renderer to graph), games was crashing while D3D init, etc... All was randomized. It is possible to make it working ?

[nevcairiel]

I have been running NVIDIA + Intel for a long time, and its working just fine.
AMD is kinda known to be unfriendly to other GPUs in the system, although i thought that was changed in more recent drivers. I've briefly used a 7750 and a Intel HD 3000 in my HTPC together, and didn't notice any issues, but it was only for a few days for some testing.

[egur]

My main home PC has HD 2000 + Radeon HD 6950. I'm not aware of any issues. When I did have issues, the motherboard was causing them.

Can i ask what motherboard do you have?
I have is Gigabyte GA-B75M-D3H 1.1.

[wanezhiling]

Its your win7s problem, install a clean win7 again.

Well, i still hoping in GBA motherboard with Haswell GT3e to replace my current setup.

[egur]

You should try updating your BIOS, might solve the problem.
I have an Asus Z77 chipset, don't remember the model. Gigabyte are considered very good too but sometimes these boards (all manufacturers) have BIOS bugs that get resolved in updates.

I'm french so perhaps i expressed in a wrong way. What i wanted to say is that using the dGPU doesn't disable the iGPU here. In fact when i plug my HDMI TV, i can use my dGPU to mix my videos and use the iGPU through Mirillis Action to record in mp4 the video window (without a single fps drops). It does work well and we can see both GPU working thanks to GPU-Z.

My trouble is just coming from the software that doesn't support intel GPU......i thought i could kind of fool it thanks to DX11 QS and Lav Video but it doesn't work. So i'll stick to CUVID

[itsonlyjustincase]

Nev has just confirmed to me that the last lav update doesn't contains the QS 0.42. Perhaps i still have a chance. I'll try it tonight
