Problem: microsoft/windowsservercore, mcr.microsoft.com/windows/servercore:1809 (and Windows Server 2016 Core, Windows Server 2019 Core) cannot transcode H264 video.
It is possible to install Server Media Foundation components in microsoft/windowsservercore, but the neccesary DirectX components are still missing.
It is NOT possible to install Server Media Foundation components in mcr.microsoft.com/windows/servercore:1809 - see below.
This github project incorporates the Microsoft example code from here:
https://docs.microsoft.com/en-us/windows/desktop/medfound/tutorial--encoding-an-mp4-file-
and adds a DOCKERFILE and instructions to reproduce the problem.
An additional binary tool, mftenum.exe is included to help validate that the Server Media Foundation feature has been succesfully installed.
In visual studio, build the solution in release x86 mode.
or: msbuild MFIsolatedTest.sln /p:Configuration=Release /p:Platform=x86
(x86 because that reproduces the build configuration of the real project this is an isolated test for)
docker build --tag sira/mfisolatedtest:latest .
docker run -it -p 4022:4022 -p 4023:4023
Note: the port mappings are for the Visual Studio Remote Debugger

In the docker command line environment run:
c:\> cd MFIsolatedTest

Observe, amongst other things:
-- Video encoders ({F79EAC7D-E545-4387-BDEE-D647D7BDE42A}) --
H264 Encoder MFT ({6CA50344-051A-4DED-9779-A43305165E35})
In the docker command line environment run:
c:\> cd MFIsolatedTest
c:\MFIsolatedTest\>mfisolatedtest.exe
Notice that it crashes, without displaying the usage text.
Use WinDbg or VS debugger, following the instructions below.
In the docker container environment do:
C:\mfisolatedtest>"c:\Program Files (x86)\Windows Kits\10\Debuggers\x86\cdb.exe" -o mfisolatedtest.exe
The debugger will output lots of info. Embedded somewhere will be a line like:
06ac:066c @ 00092281 - LdrpProcessWork - ERROR: Unable to load DLL: "ksuser.dll", Parent Module: "C:\Windows\SYSTEM32\MFCORE.DLL", Status: 0xc0000135
In the docker container environment do:
cd C:\Program Files\Microsoft Visual Studio 15.0\Common7\IDE\Remote Debugger\x64
msvsmon.exe /noauth /anyuser /silent /nostatus /noclrwarn /nosecuritywarn /nofirewallwarn /nowowwarn /timeout:36000
In visual studio, set debugging to Remote Windows Debugger with the following settings:
Remote Command: c:\mfisolatedtest\mfisolatedtext.exe Remote Command Arguments: c:\test_data\h264.mp4 out.mp4 Working Directory: c:\mfisolatedtest Remote Server Name: localhost:4022 Connection: Remote with no Authentication
Hit F5 to launch the debugger.
You should see the debugger start, then immediately exit.
Look at the Output tab and you'll see something like:
