FAudio : port request

[kencu (Ken)]

​https://github.com/FNA-XNA/FAudio

required for newer version of wine

[Gcenx]

FAudio became a wine requirement from Wine-4.3 used for xact and other wine audio backs, can also be used for porting XAudio projects to Native macOS/Linux projects.

FAudio requires SDL2, for wma support it requires ffmpeg (built with wma support) ​https://github.com/FNA-XNA/FAudio/blob/master/README.ffmpeg It would be ideal to have a variant for ffmpeg support if possible.

Hi Ken, thanks for your interest in adding FAudio!
I had already opened a ticket for this here: #58500

[kencu (Ken)]

Thanks. I looked for a prev ticket but obviously missed that one. Are the utilities worth installing, or just the library needed?

[Gcenx]

For wine usage it only needs the libraries but for porting XAudio based games from Windows to macOS/Linux the utilities would be needed

[kencu (Ken)]

looks like ffmpeg should be a variant as it changes the license significantly.

[Gcenx]

Replying to kencu:

Sorry for not making that clear, that’s the reason I mentioned ffmpeg as a variant before. FAudio is useful even without ffmpeg with wma support, of course for wine it preferred since some games do use wma.

[kencu (Ken)]

There's a new portfile with a variant for ffmpeg. I can't really sort out what tools, if any, should be installed. Most of the built binaries seem to be testing tools. The one that looked like perhaps it was useful was facttool but when i tried to do something with it, it segfaulted.

I see homebrew just installs the libraries; that's what CMakeLists.txt wants to do as well by default.

As is, it builds, including +universal, and installs on 10.14. Haven't tested anything older yet.

Can you take a look, and let me know if any of the binaries are worth installing?

[Gcenx]

I’ll try this after upgrading macports to 2.6 as I was still on 2.5.4 and let you know if it works on my end.

If homebrew just installs the libraries then it’s safe to assume those can be skipped.

In b4d8ad5daf8764753c6bd71ba73bc04ce727c4d8/macports-ports (master):

FAudio: new port @version 19.09

XAudio reimplementation of use to wine and others
optional ffmpeg variant changes license
closes: #59075

[gverm (Gijs Vermeulen)]

Replying to kencu:

Thanks for the port! Just a few things I noticed:

• Setting -DXNASONG to ON is not necessary, it's only for FNA.
  
• For ffmpeg support the readme says you need to set DFFmpeg_INCLUDE_DIR

[kencu (Ken)]

FNA?

I saw the include thing, but — we didn’t appear to need it.

Lemme know if you see otherwise.

[kencu (Ken)]

Hmm. I notice looking through the buildbot logs the build is setting the macOS version min to 10.7. That's not ideal. I'll take care of that later on, once we see if any other issues pop up.
