Apologies, I should have been clear as well. I got the error BEFORE I tried using the dummy .dll file, suggesting that whatever OpenCL support this computer has, x264 wasn't seeing it. So I tried putting in the dummy .dll file, to see if that would do the trick. It didn't. I have managed to get it working, however. I had to blow the video drivers off the system and reinstall them, and now x264 seems to be finding the system's OpenCL driver.

Is there the new x264 profiling results? I want to know which modules take most of the time.

Sorry for all the OpenCL mess; Bugmaster's written up a patch to mostly clean up the problems in the original MultiCoreWare work. It'll be in the next release.
Here's some profiling results if you want them.

You refer to this one?
https://github.com/DarkShikari/x264-...2f27d3e6646dae Looks like runtime loading of the OpenCL library is implemented now, which should make any hacks (like the dummy DLL) obsolete.

So we just need a binary release with enabled OpenCL support to test it. I believe those on x264.nl did not enable it...
Ah, no, Rev. 2310 apparently supports OpenCL in the 8-bit x86 build. But it seems to have some issues with either my card or my drivers (314.22 W7/64b)... Code:
x264 [info]: OpenCL acceleration enabled with NVIDIA Corporation GeForce 9600 GT x264 [info]: Compiling OpenCL kernels... x264 [warning]: OpenCL: kernel build errors written to x264_kernel_build_log.txt __ (0) Error: unsupported operation Last edited by LigH; 16th May 2013 at 08:42. |

I think you need GPU which supports latest OpenCL version (for example my R4850 supports only OpenCL 1.0) also 1GB is considered as minimum memory size. In order to avoid crashes people recommend even 2GB.

Quick question about OpenCL and the current x264.nl (x86) build:
I have a video card that supports OpenCL, but I do not want x264 to use OpenCL. Is OpenCL enabled by default and if it is, is there a switch to disable it? Doing a forum search I found reference to a "--no-opencl" parameter. Is this correct? |

Yes, I'm weird.

OpenCL isn't enabled by default. To enable it, you have to add "--opencl" to settings.

Any hints of what Haswell brings to the table for x264 encoding in terms of real world performance increases over Ivy Bridge or Sandy Bridge?
It seems from the profile information that Dark Shikari uploaded he's got a Haswell system. |
