x264 OpenCL & Intel HD4600 integrated graphics / Haswell i7-4770k (v. making it work)

[Stereodude]

Is there any guide or trick to make OpenCL work on the integrated HD 4600? I'm running Windows 7 x64 with the latest drivers (9.18.10.3186 from 5/17/2013) and got this:

Does x264 need a certain amount of Video RAM allocated to the HD 4600? Is there something I'm doing wrong?

I have a same problem. Anyone?

http://forum.doom9.org/showpost.php?p=1635190&postcount=1951Yes, but that doesn't explain why it doesn't work and errors out. Just that it isn't worthwhile to use.

Just so you know, I am using HD Graphics 4000 on my Surface Pro. It works on my Nvidia GT 555M.

Yes, but that doesn't explain why it doesn't work and errors out. Just that it isn't worthwhile to use.

I also have this question;
Do you altready know why it doesn't work?

[Wishbringer]

Maybe AMD and NVidia made a full OpenCL-Implementation in their drivers,
x264-developers used these complete set of OpenCL-Instructions/Implementation.
And Intels OpenCL-Driver-Implementation isn't fully compatible to specs or just faulty.
"Invalid value" says that something isn't accepted by Intel-Drivers, that works with AMD/NVidia-Drivers.

These are only my thoughts. I am not a developer.
Only they can tell you the real reasons.
Maybe they could implement a workaround,
but Dark Shikari allready answered that Intel GPUs aren't powerfull enough, so why should they waste time to make things work with GPU slower than with CPU-Power.

Thank you very much!

I never found out. I just gave up.
