it should be noted that for those that are doing comparisons of pthread-win32 threading against native windows threading that the windows threading takes different codepaths depending on the version of windows:
A) 2000/XP
B) Vista/7/(anything beyond this)

as such, comparing pthread-win32 against win32thread should take this into account.

Any improvement no matter how small is welcomed

Thanks rack04 for the 64-bit builds. Neither x264.nl nor fushizen has them yet.

May I ask: What was the main motivation to implement support for native Win32 threads? Speedup? Getting rid of pthreads?

pthread-win32 is LGPL, this causes a conflict with --disable-gpl x264 builds.
it was not done for performance reasons.

though since we were doing it, might as well use windows for all its worth when it's available (for vista+ platforms) so there might be a very small performance increase there.

[Edit]
the windows threading might be more important later when support for windows 7 x86_64's (and similar/later x86_64 platforms) way of handling systems with over 64 logical cores is added
(yes, microsoft totally made things a bit odd to extend support to 256 logical cores on the x86_64 systems starting with 7/server 2008 R2).

No it doesn't. Even a commercial x264 can link fine with LGPL libs.

It caused a conflict with a customer who didn't like LGPL libs

Excuse me, is it still worth patching ME-prepass(#5) now? (or can the patch be available now? Of course manually -- ignore patch's line numbers)

Because of large changes in x264, I want to patch it myself manually

...and another question

Is ME prepass patch (rev 680, #1) the latest?

Hi there, I'm new. I don't know if I'm writing in the right place. I have a problem with Lagarith Lossless Codec. I tried the 1.3.2.0 version and the last 1.3.2.5, but when the process finished, the output file is too small

This is the source RAW

For what I know about Lagarith, this file size is too small. I don't know if I missed something when installed it. I have the last version of K-lite codec pack for 32 bit, on Windows 7 32 bit without SP1. Anyone Have an idea?

Please read and follow forum rules, especially rule 6 regarding downloaded files, torrents, etc. Further violations will incur strikes.

Thanks for all the information and effort.
I have only one question, I use Megui 2624 (latest version) downloaded x264 2638 Kmod and replaced it by the "x264_64.exe" that was placed inside megui folder "tools".
My question is: to use a fade_compensate CLI do I have to download the patch as well?
If the answer is yes, where do I have to place this Patch?

Best regards and many thanks once again

The patch file (.diff) is not needed, that's just what the kMod creator used to build x264.exe from.

That said, it's been about 8 years since the first post was updated. It'd be nice to have a current version of this thread with up-to-date info.
