How do I use a new x264 encoder version in MeGUI ?

[VideoFanatic]

I deleted the existing "x264.exe" in this folder MeGUI\Tools\x264. From http://komisar.gin.by/ under the "clear" section I downloaded this: 2851.10bit.x86_64
I renamed it as "x264.exe" and put in the MeGUI x264 folder. Tried to encode a video and the video encoding won't start. MeGUI just says "waiting" in the queue. How do I do it?

Also is there a way to find out what x264 version that MeGUI currently uses?

The easiest way is reading the version number in the updater.

Furthermore, I executed this command in a console with the latest x264.exe you deleted:

***\MeGUI\tools\x264>x264.exe --version
x264 0.155.2901 7d0ff22
(libswscale 5.0.101)
(libavformat 58.3.100)
built on Jan 18 2018, gcc: 6.3.0 20170516
x264 configuration: --chroma-format=all
libx264 configuration: --chroma-format=all
x264 license: GPL version 2 or later
libswscale/libavformat license: LGPL version 2.1 or later

You deleted an x264 build 2901 to replace it with an x264 build 2851. Why? Obviously, the komisar build is not "newer".

I am pretty sure that there are differences in the supported command line options which make the encoder call fail (did you try to read the log file about error messages?). My guess would be the parameters for specifying the bit depth (because the current x264 combines 8 bit and 10 bit encoder in one EXE).

Because I was told the komisar version was better.

So does the komisar version have to be the same build number as the MeGUI version to work with MeGUI?

This is my MeGUI folder location: X:\Portable Installations\MeGUI 2828-32

Can you tell me what command to run in cmd please to find the MeGUI x264 version used.

Komisar builds used to have some advantages while he built them regularly. But that doesn't seem to be the case anymore... I remember a related discussion in the doom9 forum.

You can trust MeGUI being updated quite regularly, and you should assume that the developers of MeGUI take some efforts to ensure that the GUI cooperates with the supplied versions of the encoders, although that means also that they rely on a specific set of supported command line options. If you replace encoders with any other version, chances are that supported command line options differ.

If you did not delete (or restored) the x264.exe supplied with MeGUI: You can either use

x264 --version

for a verbose listing of versions of used software and libraries. Or there is also a version number in the normal help output; you may like to execute:

x264 --fullhelp > x264.txt

so you can open the generated x264.txt in a text editor and read about all options (and the version number) without any pressure.
