@BetaBoy

Hello.

Is there any plan of supporting resolutions beyond 1920 x 1088, like 4K x 2K (3840 x 2160) in DXVA mode and suitable hardware of course ?

Thanks!

I doubt there is any hardware that can accelerate 4k out there.

The Cortex A8 Allwinner A10 ARM has built-in support for hardware decode of 2k but i'm not aware of anything with 4k.

If Intel/AMD/Nvidia comes out with 4k hardware decode support i'm sure CoreAVC/DiAVC will support it.

Radeon 5000 series with UVD 2.2 are capable of 4K since April 2010 with Catalyst 10.4
But there were no suitable decoders/players to support it due to Nvidia restrictions.

As I have proved here http://forum.doom9.org/showthread.php?t=163110 even UVD 2.2 is more capable than most people think.
UVD3 supports 4K too.

I thought now that there is VP5 which seems capable of 4K, Nvidia should be more flexible to allow 4K in general and pull back the pressure of not allowing 4K decoding on ATI hardware.

So from the side of hardware and driver, UVD 2.2 is capable of 4K x 2K and if CoreAVC DXVA is capable of 4K x 2K, as it is clearly seen by your screenshots, then the problem must be an artificial restriction in everything else but VP5 inside the code of CoreAVC DXVA.

DXVA checker reports for clips beyond 1080p and CoreAVC DXVA the following:

"ModeUnknown (NV12): DXVA1 (VMR)"

and of course it's not working.

@BetaBoy

I would like to check my "fused" 5750-6750 card in 4K x 2K DXVA with its "supernatural" video decoding capabilities as I have clearly demonstrated here:

Because VP4 is very slow at high bitrate clips as you can see here http://forum.doom9.org/showthread.php?t=163110, UVD2.2 was forced to be incapable too for 4K x 2K in order to have comparable performance with VP4.

Nvidia had always a few ways to do things like "The Way it's meant to be played"

UVD2.2 in 5xxx series was too fast when introduced back in October 2009 and with Catalyst 10.4 - on April 2010 -it was ready for H.264 L5.1 including 4K, as it is written in Catalyst 10.4 Release Notes.
I can send you the file if you can't find it with google.

As you can see at the above link, UVD2.2 is more powerful than it seems and the reason that is lowered is not Nvidia only, but ATi too, mainly ATi I could say.

ATI wanted to sell UVD3 for MPEG2_VLD, MPEG4ASP_VLD and 4K H.264 playback.

All of them are features of UVD2.2, that have never activated in order to "push" you to buy the next generation card.

Even now if you force MPEG2_VLD, MPEG4ASP_VLD and 4K H.264 playback in UVD2.2, you get a normal playback mode with a GREEN FRAME covering the picture of the video file.

They don't want you to see the clip!

Of course all of the above are a joke, just a conspiracy theory I invented with my vivid imagination...

if ati uvd 2.2 is so fast then why doesnt it show so in the benchmarks? looks like its either more of a hardware limitation or a driver lmitation. nothing is showing that its being held back by nvidia. last time i checked its the standard dxva mode that ati uses for hardware acceleration, and there is nothing nvidia can do to influence dxva acceleration.

unless you mean that the uvd2.2 is being held back by not having cuda support?

if you get green frame during playback its usually a sign that your hardware cant decode properly due too an out of spec input file. i get that a lot on my old mkv media player if i encode files with too many reference frames.

Any news on fixing the TrueHD mediatype issue with Haali splitter? If it has been fixed already, could to link to a new build so we don't have to wait until next CoreAVC release?

I'm interested to know this as well.

Whatever happend to CoreMVC? Wasn't it supposed to be released right after CoreAVC 3?
It seems to have a big marketing advertisement page on their website, but no download/purchase possibility.

It has been out since last February, but only for OEM licensing in both library and directshow forms. Based on feedback we opted to push out a consumer directshow decoder till after we added 4:2:2 and 4:4:4 in CoreAVC. We will revisit a possible release afterwards.

The fix will be included in the next CoreAVC release.

i hope it isn't to late yet, though maybe this is already fixed then you can ignore it

http://www.mediafire.com/?rnj806aa6tgjrp9

the issue is after the glitch Lav Splitter,Haali Splitter,MPC-HC splitter (Lav Audio) doesn't Recover with CoreAVC it begins to stutter (frames are dropped) (Software,DXVA,cuvid not tested) it works fine with Lav Video (any mode, cuvid not tested) see https://forum.doom9.org/showpost.php...postcount=8655

@BetaBoy

Is it possible to clarify which path do you enable in order to HW accelerate H.264 files on Intel's QuickSync HW ?

There are a lot of confusing and contradicting issues regarding Intel's HW acceleration.

For example CoreAVC 2.x has DXVA support which utilises ModeH264_VLD_NoFGT but not for Intel.
It doesn't work.
It was Core AVC 3.x which added Media SDK and GMA support.
Do you use ModeH264_VLD_NoFGT or ModeH264_VLD_NoFGT_ClearVideo in order to HW accelerate H.264 files in CoreAVC 3.x ? Or something else ?
Because the performance of CoreAVC DXVA with QuickSync HW, indicates that it uses some direct mode of DXVA and not copy-back like QuickSync decoder by Egur.
At the same time using Intel's Media Checker tool, I saw that CoreAVC 3.x during HW accelerated playback on QS HW doesn't use Media SDK decode operations.
No HW calls, no SW calls of Media SDK.

So what is the mystery of CoreAVC 3.x and what's missing from CoreAVC 2.x ?

Is it a direct use of Media SDK - without copy-back- that Media Checker is not capable to catch ?

Thanks in advance.

it uses the ClearVideo mode like any other ISV does, copy back makes no sense for a On screen Decoder if you have Native DXVA support why the heck you would want to use copy back for playback ?
Copy Back makes sense to be used in a Decoding(DSP,GPU)->Encoding(Software,DSP,GPU) scenario where you balance both out so the CPU overhead can be compensated efficiently so the Encoding stays lower Power and Faster then without Copy Back (Software Decoding)
Or if you still need acceleration and lower power and combine it with a 3D renderer (for example a Broadcast Editing system with complex layer setups)
But for a consumer Playback system it makes no sense and isn't beneficial @ all @ least on Windows

I didn't say CoreAVC uses copy-back.
I said the opposite, that they don't use it.

But CoreAVC supports Media SDK after CoreAVC 3.x.
ClearVideo support was there in CoreAVC 2.x, but QS HW support in CoreAVC 2.x wasn't.

You put PotPlayer and MPC-HC in ISV's too ?

What do they (PotPlayer and MPC-HC) use with their internal codecs in order to accelerate in QS HW the H.264 video ?

The same ClearVideo DXVA interface, though CoreAVC uses some clever workarounds the same as Mirillis does for several special decoding issues

Not every DXVA decoder is the same only because its using the same interface

Arcsoft and Cyberlink are currently also going this way trying to fix issues with workarounds
