Intel QuickSync Decoder - HW accelerated FFDShow decoder with video processing

[iwod]

I did a search and nothing came up, its there a reason why Intel Quick Sync Encoder and Decoder are not available on Mac OSX platform?

because no one has written one. at least this decoder is written for windows directshow.

MacOS leverages the Intel hardware for accelerated decode and like encode, however. So it's more a lack of a direct SDK versus the MacOS X APIs.

Will QuickSync variable refresh rate playing at the maximum frame rate be fixed or is it a problem with QuickSync that can't be other than by Intel? LAV has the same issue.

I believe this is the same problem: https://trac.mpc-hc.org/ticket/5110

[amayra]

is this latest version of ffdshow ?

[clsid]

No, latest version is 1.3.4533.

Development of ffdshow has stopped long ago. You should use LAV Filters instead. DXVA2 is also better than QuickSync.

Unfortunately it had some very unique ideas that gone lost with it.

Anyone with Cherrytrail/Braswell can test to help?

Your graphics driver is very old, try updating to 20.19.15.4501.

That didn't install on Braswell.

PJ which sample is that ?

Would like to test it on the Bay Trail Celeron Decoder previous version of your Chip, essentially

Bay Trail doesn't support HEVC at all.

Well, I found what was the issue, Braswell can't handle any 4K 50/60fps:

As wanezhiling said no good idea to use EVR CP for such a low power platform it's overhead could be already way to much and latency for that Playback Scenario way to high.

Especialy with the OSD active.

This isn't really different as if you try a High Complexity H.264 4K with Bay Trail it will fail the same way on EVR CP it works way way better on normal EVR.

You could also try to higher the EVR CP Buffer to smooth it out but it wont do that much magic if the whole system is to underpowered for the complexity level .

This Price Range of Systems is entirely only optimized for the normal customer WEB Experience you pressuring that low cost System heavily no normal user would do that, and you expect official support for that .

NO Professional would even come to the idea asking Intel this.

60fps 50mbps that is not really a normal Scenario of Complexity for a AVG usecase for such a low cost System especially not in it's so young development timeframe.

60 FPS Broadcast Decoding is a whole different area you expecting to see working for this Generation.

Jesus you should be jumping around reaching 30fps 80mbps on that first generation low cost x86 system

You wont get anything else from Nvidia for example that could do this in the x86 space for that price

I mean you totally make yourself a fool there especially with such nonsense you majorly hurt your credibility over there

As you see, 4K doesn't even touch 1GB of VRAM and Braswell can't handle any 4K 50/60fps, no wonder since Intel makes the worst graphic cards in the world.

And you seem to have 0 knowledge of Intels GPU Architecture as well, else you wouldn't say such a nonsense, what they achived over the last years from GMA to Intel HD is pretty Amazing.

[P.J]

Plain EVR can't help too since Braswell iGPU is damn weak and that's not because of the RAM/VRAM as they said incorrectly.
Wonder why it crushes the colors in H.265 but no problem with H.264. HEVC 8-bit is useless too since 10-bit has already replaced it.

[CruNcher]

Yeah sure has already replaced it you are the only existing human on earth i guess also

We are right in the transition phase to 10 bit customer content and mostly only for 4K Premium Content and you speak about has replaced it already, listen to yourself.

[P.J]

What exactly do you mean here? You haven't been forced to post when you can't help.

Hope someone can find a newer driver for Braswell than this one:

Try uninstalling the Asus customized graphics driver and see if the Intel driver would install, since the Intel installer is detecting Asus' customized driver.

No guarantees though, make sure you have the Asus driver installer if you can't install the Intel driver so you have some working driver to fallback to.

But yeah, this is one reason to hate Intel's annoying stance at not supporting their own hardware with driver updates if the OEM decides to have customizations.

Thanks a lot, that trick worked fine
Yea agree, that's why I sold Surface 3 but my 10 years old 8600M GT has still a Windows 10's driver.

If the generic Intel graphics driver installer EXE refuses to install because it detects a OEM video BIOS and tells you to use a OEM driver instead, you can simply work around this by manually installing the generic Intel driver from a ZIP package via the Windows Device Manager, which Intel is even providing instructions for on their website, see:

Thanks, will try it if it happened next time.
And Intel makes things more complex

This is the last of version 15.36 driver to support 4th generation on Windows 7* and Windows 8.1*. No further drivers are to be expected for this generation on these operating systems.

Intel 10.18.14.4578 Win7/8.1 last driver for Haswell on Win7/8.1. Broadwell's driver support is on a newer driver branch and still supports Win7 & 8.1 on that driver branch in addition to Win10. Haswell on Win10 also uses the newer driver branch and is still supported.
