autodidact

I think if you are using a pre-built mingw toolchain, most are the default minimum of Windows 7 so the winpthreads will be incompatible with Windows XP. I built a XP compatible toolchain from scratch to avoid those problems. The @Reino script also does that and uses pthreads-w32.

This is untested. ffmpeg-8.2-1021-739fc9249c-win64-static-xpmod-minimal.7z

Test build. Minimal static XP build for use with yt-dlp. ffmpeg-8.2-1021-739fc9249c-win32-static-xpmod-P4-minimal.7z Is it enough?

FFmpeg update. XP: shared static libfdk-aac VISTAx86: shared static libfdk-aac Maybe these will be the last of the large XP builds.

I was going to post new builds today but maybe we need to discuss a more targeted configuration. If we can define the core requirements I would be happy to make minimal builds. I see @reboot12 even removes ffplay which further removes an SDL2 dependency. These things do add up in size.

OpenSSL 3.6.2

Updated FFmpeg links in the post above.

@nicolaasjan I have attempted to make compatible 64-bit OpenSSL shared libraries using MSYS2. If you would like to test them.

FFmpeg update. XP: static shared libfdk-aac VISTAx86: static shared libfdk-aac

Either libfdk-aac library should work fine on Vista. The Windows 7 version was compiled with GCC 15 but it looks like I neglected to strip the file so it is larger than it needs to be. I will link a corrected file next time. Thanks for bringing that to my attention.

I guess the extra features fulfills the plus part of Vista+. I understand the desire for targeted features and size reduction though. Now, with a known working configuration we can certainly remove features. That part will be easy. I can start with the items you listed for a future build. The libfdk-aac external functionality is included for parity with the XP version and of course the dll is not required to run the FFmpeg binaries. This functionality can also be removed if desired.
