[FFmpeg-devel] Converting build to CMake

[FFmpeg-devel] Converting build to CMake

[Jaime Rios]

Sorry if this has been asked before in the past.

I am wondering if there has been any conversation around changing the
current build setup of ffmpeg to CMake.

The reason I ask is that I am not a fan of having to install MinGW just to
build on Windows, and my experience so far with CMake has been a pleasant
one, when having to build on multiple platforms (Windows/Linux/macOS).

If there has been conversation about moving to CMake, where can I find the
thread?

Thank you.



-Jaime

I would love that to happen myself too.  The main issue is all the 
dependencies that ffmpeg has to take care of. You need to have 
FindLib*.cmake and/or BuldLib*cmake, plus you need to take care of which 
libraries are open source, BSD, GPL, etc. and whether you need to locate 
them with pkgconfig.

It is overall a lot of work, so something would need to get paid to do 
so fulltime.

I have to wonder, as I only have Windows 8.1 so far, doesn't Windows 10 
WSL2 solve the compilation issues by having the lib be compiled on an 
Ubuntu distro?

There is a (maintained) fork of FFMpeg with Meson (similar to CMake):
https://gitlab.freedesktop.org/gstreamer/meson-ports/ffmpeg

However, this has nothing to do with the original project (AFAIK).

Best,
Gerion

There's no need to install MinGW, just MSYS will do:

I might take a look at the dependencies and see what projects could be
converted to CMake first, before even thinking about ffmpeg.
