x265 HEVC Encoder

We've made a number of substantial improvements to x265 in the past few weeks. x265 documentation can be found here... http://x265.readthedocs.org/en/default/

It seems there a typo on the latest evaluators guide...
The new option "rd" appears as "-rd" on changes and suggested settings, and as "--rd" on "Standalone Executable Options" later on the same guide.

PS: only --rd works on x265.exe.

Has anybody ever tested the following statement?

Quote:
If not building in Windows XP but want the binary to be XP-compatible, enable WINXP_SUPPORT Cmake option.
Because so far, I still haven't seen any MSVS build of x265 compiled on a non-XP machine that can actually run under Windows XP.
Either you get the error message

Code:
The procedure entry point InterlockedCompareExchange64 could not be located in the dynamic link library KERNEL32.dll.
or you get the error message

Code:
"Path-To\x265.exe" is not a valid Win32 application.

Thanks. Microsoft Word was auto-correcting double hyphens (--) to a single dash (–), driving me crazy until I found the setting that prevents this. We've posted a corrected version of the guide. x265_Evaluators_Guide_09-24-13.pdf

We welcome participation in the project in every way, including help with better documentation (explanations of settings, etc.) and with any feedback on usage, etc. This has been challenging up to this point as x265 has been a moving target, undergoing fairly substantial fundamental changes over the past 6 months. We should be evolving to the point where we are doing more performance optimization of the existing algorithms, rather than replacing / implementing them, and to where we are able to focus on additional features and platforms.

We continue to experiment to find the most optimal settings for different situations, and we expect to have x264 style presets at some point (slow, faster, fastest, etc.). But we also welcome feedback in this area.

Thanks
Tom
