No other bottlenecks. --threads 4 I'm fine. --threads 8 I'm fine. -threads 12 it chokes other things, though the encode runs fine.
i7 4790

If it's pegged at 100% util my computer acts like it's 100% util at a higher priority.

Anyone got a link to a current, statically linked, x264 version with libav in it that's for MacOS X ?
Latest build over at http://download.videolan.org/x264/bi...macosx-x86-64/ is from 25-Dec-2017.

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).
