Thank you. a public version of the Windows DLL is on our to-do list.

If you’re willing to accept a CMake build system, I’ll build a crossplatform one that works everywhere for you.

We accept CMake related PRs, please do.
MediaInfoLib already has it (also from a volunteer).

I’m already doing this work to make it possible to build mediaconch into my Python extension. Including the CMake with the source will make it so I don’t have to overlay my own build system. It’s a win-win.

If I’m going to make it useable for others I have two questions:

1. Do you have a minimum cmake version you want to support?

2. What C++ standard are you targeting?

If I’m going to make it useable for others I have two questions:

1. Do you have a minimum cmake version you want to support?

3.5 is the minimum since compatibility with CMake < 3.5 has been removed from CMake 4.0

2. What C++ standard are you targeting?

Currently MediaConch targets c++11
