New version released 0.38 beta

Version 0.38 beta is out with the following changes:
* A fix for audio sync issues in broken streams.
* Bugfixes for broken Win8 drivers
* Better handling of incomplete sequence headers.
* Able to recover after multiple initializations. New stream must be from the same codec as the old stream. Calling InitDecoder or SetConfig will reset the decoder.
* FFDShow: Added fine grain multithreading support
* FFDShow: r4477

Note to Window 7/8 users with drivers 15.28.xx.xx:
Do not enable full multithreading support in FFDshow or player will abort playback at some point in many clips.

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

Great. I'll wait a few months before even considering using it at home.

Judging by Metro UI, I would say to not consider it at all using Win 8 at home on a computer.

Metro UI was built for tablets and touch screens and probably I would skip that version of Windows completely, if "classic" Windows Explorer didn't exist at all.

On the other hand, we are more or less at the enthusiast community so I will definitely install Win 8 - as second system - no matter what, as soon as I get a copy in my hands - I have already seen Win 8 preview release on my older second system.

Quicksync not chosen on H264 tv

It works ok with Lav Filter, but, when i try to use FFDSHOW, despite i have chosen intel QuickSync, FFdshow says it uses Libavcodeck on H264 (TNT HD).
FFDSHOW says it uses Intel on non hd channels (mpeg2), so i believe install is correct.
I had tried both 64 bits and 32bit version as i use DVBViewer which is in 32 bits to watch TNT TV.
What the hell ?

(My config: Seven 64 bits with a Sandy bridge GT2 i5-2500K @ 4.6Ghz (HD graphics 3000) on a Z68 chipset and 4GB of ram)

What's the driver version? Splitter version?

FFdshow and Lav : Last ones. Downloaded yersterday.
Intel Driver : 8.15.10.2696

Not a big problem, as LAV works perfectly and i can use FFDSHOW raw for some additional post processing. it is just to let you know and to try to understand what happens as well.

Unfortunately, I can't test live TV streams since I don't have such a source available.
You can try installing a newer driver (from the 15.26 family) although this driver worked fine as far as I remember.
Can you play H264 files?
If LAV works with QS decoder and ffdshow doesn't, it means that some checks within ffdshow fail.

The last one i found at Intel download center is win7_64-152612 Version is 8.15.10.2761
Despite Windows said i had the latest ;-(
Same behavior.

Yes, you're right: ffdshow says "Intel @Quicksync" with recorded files from TNT. Strange.

Unintelligent connect from Directshow ?

BTW, do-you have contact with this guy ? : http://doom10.org/index.php?topic=717.0

Also, i experience some freezes after long playings of tv streams with Quicksync. Closing application then reload, changing channel or rebuild graph and it is good for an other run. No such a problem with software decoders.

FFDShow may recieve an incompatible fourcc or something of the sort. I don't know and can't test this.

I don't know the guy in the post. Intel 100K employees...

does the intelquicksync hardware accelerarion only work when having an i5 (or similar cpu) AND the intel HD graphic card both running at the same time?

in case of the avatar 60p demo, I get almost 400fps with the intel decoder, compared to only 120 with coreavc. but since I use madvr, the intel card with only 25gb/s bandwith seems to be rather weak here and I get dropped frames if I priorize it over the Radeon mobility 7670, no matter which decoder of coreavc, lav video or ffdshow I use in both cases. it seems like the huge decoding advantage gets lots by the intel HD 4000 graphics cards bad performance with madvr.

or am I doing something wrong?

Sorry for the late response, I was on vacation w/o internet.
You'll need a VS2010 and able to build ffdshow.
Another option is for me to provide a debug build that pops a lot of message boxes showing the status. Let me know which option is preferred.

Unfortunately, the decoder will work only if the iGPU is active - connected to a screen. A Direct3D9 limitation.
There's an option to trick D3D9 by extending the desktop to a disconnected display. See here.

As i do not develop under Visual Studio since decade, this second solution seems more reasonable on my side. But blind and time consuming on your side ?

is there a way to utilize quicksync decoding function with MeGUI or avisynth like DGDecNV can use Nvidia GPU's

i'm looking for any feedback, or theory's. is this something that can be done, or will it be like AMD (radeon) where the decode information can't be gained easily

i know that GPU can help in some respects, yet i would of thought it would be even better than Nvidia GPU decoding as intel in on chip (no motherboard travelling kind of thing with information bottling the express lanes)

can i use the FFDShow to assist MeGUI (offloading H264 decoding to GPU) so MeGUI x264 wil be faster.... even 15% gain in speed would be great.


if not..... will this or could this be possible, or will quicksync be like AMD (radeon) system where the decoding information can't be got at for make use outside of directx (avisynth needs to be the one to have the info)

Perhaps, you can try to create a .grf file (see here http://avisynth.org/mediawiki/Importing_media ) with ffdshow/lavfilter quicksync decoder and load it in avisynth with DirectShowSource().

ffdshow/lavfilters can be used with QuickSync as long as a display is connected to the Intel GPU in some manner.
The performance gains are not as trivial as standard decoding because all HW decoders output NV12 and avisynth wants either YUY2 or YV12. The latter is preferred as the conversion is lossless and very fast. Video renderers on the other hands like to get NV12 so no conversion is needed.

As far as complex/smart transcoding flows where meta data from the decoder is used (e.g. motion vectors or quantization parameters), I'm afraid we're out of luck. The driver doesn't expose those which is a shame since this information is useful for denoising/deblocking as well.

i see, so partially closed than like AMD, nvidia seems to be the only one that has really opened this area up, it'a an awful shame that so many developers still don't take into account that Avisynth is where the power is (so much can be done with Avisynth), here's hoping that programs like DGDecNV can be created for intel quick-sync.... although it's worrying about the NV12 needing conversion...... Nvidia GPU architecture doesn't have this issue though... why? it's still a GPU (VP decoding chip)

NVIDIA also outputs NV12 from its GPU decoder.
