Well that sounds very good. Hopefully you can achieve sth. sooner or later

With mkv not supporting DV you mean Matroska as the stream, right? Cause there are mkv containers with mpeg-ts Dolby Vision streams, that seems to work. But the matroska stream doesnt work?!

For example this one is an mkv: https://drive.google.com/file/d/0Bwx...dZaGtaVm8/view

Oh jeez @d3rd3vil,

That so-called 'sample' is a classic example where some idiot has simply changed the file extension from .ts to .mkv

The sample has not been muxed into the .mkv container!

Just in case you do not yet know already: The intel C++ compiler under Linux is not compatible with glibc 2.24-9 and newer, because:

According to x86-64 psABI, xmm0-xmm7 can be used to pass function parameters. But ICC also uses xmm8-xmm15 to pass function parameters which violates x86-64 psABI.

As a workaround, you can set environment variable LD_BIND_NOW=1 by

# export LD_BIND_NOW=1
This seems to be exposed especially on CPU's with AVX support. Of course, x265 will mainly use hand-crafted assembly where possible. But where this is not yet available ... you may have to be aware of possible risks if a recent version of glibc is used (well, I am not sure if x265 uses that, but I believe it is a quite basic library).

There are bug reports from the glibc project and RedHat.

Please don't mind me if this issue is irrelevant for x265. I just assumed that a cross-platform project using AVX instructions may be among the possibly affected.

Hey Guys

Im encoding some Videos to h.265 using megui and x265 Encoder.
In 95% everything runs smooth, but from time to time i encounter an error. Half of the time when i restart the encode, it works, withouth changing anything.

Here is the Log:
[Error] Log for job3 (video, Matrix.(03).2003.Revolutions.German.AAC51.DL.1080p.BluRay.x264-Kristallprinz.mkv.avs -> Matrix.(03).2003.Revolutions.German.AAC51.DL.1080p.BluRay.hevc)

There is more than enough free HDD space, that cant be the problem.

I run two Workers simulatneously, one with --pools 36,0 and the other --pools 0,36

It also happens when i set --pools 36,36 (running two or a single worker)

If you need any more information, let me know.
