His site is back.

But maybe unfortunately, since he doesn't provide fresh x264.exe builds anymore :-/

In nvenc (Nvidia encoder) there is a parameter enableConstrainedEncoding. This parameter is relevant for multi-slice mode and if it's set then motion vectors are restricted to not cross slice boundaries. That mode is useful in error resilience (to constrain error temporal propagation within the boundaries of a corrupted slice) and in delivery of 360 video.
My query - is there a similar mode in libx264?

Hmm, I know that x265 has a choice between WPP and other parallelism modes, also a slice oriented mode. But I don't remember x264 having a choice.

@LigH: for x264 = this?
Quote:
--slices
Default: 0

Sets the number of slices per frame, and forces rectangular slices. (Overridden by either --slice-max-size or --slice-max-mbs if they are set.)
If you are encoding for Blu-ray, set this to four. Otherwise, don't use this unless you know you need to.
but imho nothing about "enableConstrainedEncoding" except:
Quote:
--constrained-intra
Default: Not Set

Enable constrained intra prediction, which is required for the base layer of SVC encodes. Since Everyone ignores SVC you can likewise ignore this switch.

Possible, if enabling slices also ensures that MV's are constrained to each slice. I hope the developers in #x264 on Freenode know more, just asking... I'm no developer.

BugMaster mentioned a guess that --sliced-threads may have such a side-effect.

WPP is new and so for unique feature to HEVC. The next gen VVC (probably H.266) currently plans to not include WPP.

Now available in my archive too: x264 0.157.2935 545de2f (compiled already 2018-09-29 but forgot to pack and upload).

Today I wanted to recompile again with updated FFMS2 and L-SMASH ... but suddenly ffmpeg fails compiling libavdevice, seems to be a GCC 8 specific issue (expecting an explicit cast to (void) in a #define).

I found that current x264 builds for some reason don't include libswscale, I was going to perform some speed tests comparing it to multithreaded avs+ resizers, even if the quality is not as great. If anyone knows someone who build them specially 10bit x64 please let me know.

Which specific build are you referring to?

As far as I can tell, the latest Ligh, msystem.waw.pl and videolan.org builds all do include libswscale, i.e. the "resize" filter is available. See download links in first post.

BTW: For quite some time now, there are no separate "8-Bit" and "10-Bit" builds anymore. You can set '--output-depth' at runtime now (details).

Thank you it works! I was testing with x264 tMod (jpsdr), x264 Ymod (YamashitaRen), x264 videolan. tMod warns about the merge between 8 and 10bit builds so I thought it was important.

Cool. Because I was just going to 'complain' that the 10-bit versions of x264 don't appear to be compiled with OpenCL support.

Well, the person maintaining "tMod" build obviously did not bother to port all of the "custom" patches to latest x264 after the "8/10 bits unification" (Dec 2017), which was quite a big change in x264 codebase.

Instead "tMod" build seems now to be based on an old version of x264, just before the big "8/10 bits unification" happened – with a some fixes cherry-picked from x264 master...

P.S. Are there any advantages using LigH's x264 over the regular one? (at videolan)

Videolan.org build does not have FFmpegSource2 support enabled.

Also latest Videolan.org build was built using GCC 6.3.0, whereas latest LigH build was built using GCC 8.2.1 – which could be faster or slower, but probably doesn't make much of a difference.

LigH build includes a somewhat newer libavformat version.

It's just what the media-autobuild_suite produces, no additional changes. Look here for download link and version details.

Cool. Thx. I took the one from the start-post link (the one I'm encoding with now). It is dated Dec 13, 2018, so it looked pretty recent to me.

P.S. Yours -- apart from being compiled with a later compiler -- also appears to be a lot smaller (~14 MB vs. ~22 MB).

Maybe the other one forgot stripping compiler symbols.
