Intel Media SDK - Quick Sync Video

Hello fellow video technologists -

Long time follower, newb poster. I'm the Product Manager for the Intel Media SDK, the free SDK that allows developers to gain access to Intel's line of HW acceleration technologies now built into our main Core line of processors.

Any technical issues must be handled in Intel's free support forums .

I will also not be able to disclose any non-public information in a public forum, so please be understanding if any of my answers are vague around future chipset features or SDK releases.

I'll be monitoring this for general questions and comments and suggestions about our technology/samples/products/tools. You can always contact me directly via twitter @IntelMediaSDK.

In fact, we are giving away 2 Core i7 2600k CPU's by the end of the week for anyone that follows/retweets by 6/28/12 @IntelMediaSDK. (must be in the U.S.)

I'll also be at SIGGRAPH 2012 in LA - we'll be giving away some IVB Ultrabooks and Intel SSD's at the show - so ping me if you want to meet up in August.

-Ryan Tabrah

You mean you will randomly choose 2 followers to give the CPUs to? How do I "follow" you to be included in the drawing? Have to have a twitter account?

Yes - you must have a twitter account and then become a follower of @IntelMediaSDK. (this is free to do) We'll randomly choose a follower (we don't have many). If you retweet about our drawing, you'll get 2 entries.

I was literally cleaning up my cube and found these and its a tragedy that they are still in the box. These CPU's need a new home.

What if we don't want to have a twitter account? Seems a bit silly to force some stupid social media thing on people. I'm a developer that could probably do you some good. I'm excluded because I don't want a stupid twitter account?

I've not addressed your technology previously though people have requested it because I don't have a suitable CPU. Can I at least be entered in the drawing?

We totally understand not everyone is a user or fan of social media. I'll be happy to enter you manually - no problem. I just wanted these CPU's to find a good home.

Thanks very much, Ryan!

And thank you for your PM which I will respond to shortly.

And one more thing...welcome to the forum!

ciao,
Don

Welcome 1 request unlink the Display Connection from the DSP usage, im currently switching like in the 90s displays just to be able to use the DSP Encoder and im not sure for what you would need Virtu for this as the end result endsup in a file not on screen (Unlocked & Unleashed)

@rtabrah
1 of those puppies would find a good home @ neuron2 for sure

That might result in a DGIndexQS from neuron2, which will make a lot of the users on this forum quite happy

I upvote the idea to donate one CPU directly to neuron2, he surely deserves that and might contribute to wide public much more than any other "random lucky bastard" who just happened to have a twitter account. Honestly, if only this is supposed to be a "feature" that gives one an advantage at drawing then I don't know what to say about such attitude of a donor.

Hello Ryan.

For some reason I didn't know about this thread, I thought only Eric had an Intel thread.

One question:
Is there any particular reason that Intel MSDK is using DXVA copy-back and not direct, vanilla DXVA ?
The latter is preffered by many people.

The MSDK does nothing of that sort. Its just an API to decode video. The decision to copy the image to system ram or keep it on the D3D surface is completely up to the user of the API.

That answer surprises me and I have to ask, then why don't we have a QuickSync decoder utilizing native DXVA through MSDK ?

I've asked Eric and I think he replied because of MSDK restrictions....

Nev, can you and Eric and Ryan cooperate in order to have a native QS decoder ?

Next question:

Why Intel is keeping VC-1 non DXVA compliant ?
H.264 and MPEG-2 are working fine with DXVA.

What's so special with VC-1 anyway, to have a different treatment ?

We could, but we have better things to do. The "many people" that prefer it is just you.

Ha, ha
You are funny.

A native QS decoder with minimum CPU utilization and minimum Power requirements for desktops/ servers/ laptops is only for me ?

Why do you even bother involving to HW acceleration ?

Leave it to CPU decoding if it's only me...

The MSDK includes a decoder filter that does exactly that. I modified it a little to add QS transcode support in DTB.

Sorry for the delayed response - its been a busy January:

Your questions about DXVA copy-back vs. vanilla DXVA and VC-1 are somewhat related to design decisions around our HW/driver solution. One of the reasons the Intel Media SDK was designed and productized was to make it easier and simpler for developers to access HW features without worrying about DXVA compliance differences between driver or HW iterations. That being said, if you need help with working around these specific issues, my enabling engineers have said they'd love to support your efforts. Feel free to post specifics in a private or public fashion on our support forum or you can email me directly and I can get you connected with the right folks.

Great answer - the Intel Media SDK is actually primarily an interface to access HW acceleraters for Encode, Decode, Transcode, and Video processing filters - not just decode.

Unfortunately you weren't randomly picked. I'll keep you posted if there's another drawing or giveaway.
