x264 test build with opencl lookahead
The x264 opencl lookahead patch has been tested for months on x264dev’s IRC, but it lacked too many features compared to currect x264, e.g., the weightp was still not supported at the beginning of May. However, it is glad to see the latest patch was released on doom10 yesterday, in which most features has been implemented (but only 8-bit, high bit-depth has not been supported). So a test build should be available here.
Based on tMod+MixAQ branch (rev2197+666+30). Compiled with fprofile and win32thread, and AMD APP v2.6, which may require OpenCL v1.1 runtime to enable opencl lookahead. Lavf/ffms/swscale/interlaced was disabled, and chroma format was set to 4:2:0. Tested on AMD HD6770M and NVidia GTX460, not sure if it can run on Ivy Bridge or not.

See the latest x264 build page for newer builds.
Attention: the patch may not be stable enough for everyday use, so this build should only be used for test purpose. Not only speed but also encoded results are not identical with or without opencl.
