x265 missing, 'null' is in its place

[dipswitch]

I really have no idea

Neither do I 

Only thing i know is that the overnight build gives me hevc output.

That nightly is a MinGW build, right? Builds which exhibit the problem are VC++ builds.

This is correct.What i didnt understand: i'm using avidemux for some time now. Suddenly the installer has vc++ in its name. Didnt actually new what was going on. Now i seem to guess there is something changing in the way avidemux runs? it ran in a mingw environment and this now is shifting to microsoft visual c++? Was mingw no good?

Official release builds were moved to Visual Studio between releases 2.7.1 and 2.7.2 because MinGW builds are (almost) impossible to debug.

[eumagga0x2a]

There is a new VC++ nightly build with some (unrelated) changes in the build environment --> https://avidemux.org/nightly/vsWin64/Avidemux_2.7.4%20VC++%2064bits%20190826.exe

Could you please try it and report back whether the x265 encoder plugin in this build loads or not?

[eumagga0x2a]

By the way, we have verified with TO that the checksum for the plugin DLL matches, but we haven't checked libx265.dll itself. Could you please check that the libx265.dll the HEVC encoder plugin needs to load has MD5 equal

If you have installed Avidemux VC++ to C:\Program Files\Avidemux 2.7 - 64 bits, then please execute

Code Select Expand

cd /d "C:\Program Files\Avidemux 2.7 - 64 bits"
certutil -hashfile libx265.dll MD5

Who are you asking this? Me or @chairman.faust  ?

[eumagga0x2a]

You (though it wouldn't matter if the TO responds too). It is about excluding the option that libx265.dll is corrupted.

Have you already tried the new nightly? (libx265.dll there is exactly the same as in the release, but as we don't know what is causing the problem, trying should not do at least any harm).

[eumagga0x2a]

@dipswitch: It would be really desirable to know for sure whether libx265.dll from the Avidemux VC++ install directory on a system, where the HEVC encoder plugin is missing, is undamaged, i.e. whether the checksum for this file matches. This is IMHO even more important than to try the nightly which fixes PNG decoder in the internal ffmpeg missing (libx265.dll in this nightly is exactly the same as in the 2.7.4 release).

Of course, should libx265.dll turn out to be damanged, this would imply something very selectively messing up the extraction of the 7z archives with all the components of Avidemux stored within the QtIFW installer file.

On the machine with no hevc output, avidemux 2.7.4 was installed in C:\Program Files\Avidemux 2.7 VC++ 64bits

The MD5 checksum of libx265.dll is f9b31d6a0e526efbd048b1073f795373     (i checked twice).

I installed it and there still is no hevc output on this nightly build.

The md5 checksum for libx265.dll on this build is f9b31d6a0e526efbd048b1073f795373 . Seems something is really messing up the x265 dll.

[dipswitch]

Strangly enough, the not working libx265.dll is exactly the same size as a working one: 6.065.152 bytes.

But things get weirder, the md5 checksum for libx265.dll on the working 2.6.4 install on another machine is also:

f9b31d6a0e526efbd048b1073f795373

And when i copy libx265.dll from a working install on another machine to the not working avidemux, it still doesnt work, i still dont get hevc output.

I'm lost.

[eumagga0x2a]

Thank you for checking this, one more possible reason for the issue ruled out.

[eumagga0x2a]

Probably a completely bogus idea, but is there any other software installed which has libx265.dll bundled?

(bogus because usually the application install dir is searched for libs first)

[dipswitch]

i've searched the entire hdd for libx265.dll, only the one from avidemux is there.

[eumagga0x2a]

Okay, thanks. I could only suggest to try the following: uninstall 2.7.4 VC++, install 2.7.3 VC++, make a copy of its older libx265.dll, uninstall 2.7.3 VC++, install 2.7.4 VC++ (release or better nightly as the latest nightly has the PNG decoder which is missing in the release), replace the newer libx265.dll with the older copy. Does it work?

Did you read my previous post, where i explained that the libx265.dll from the working avidemux has exactly the same md5 checksum and size as the non working installation? strangely enough the md5 checksum doesnt match the one you provided, how is this possible?
