ffmpeg - 未知操作系统 'msys_nt-6.1'。在 win7 64 位上使用 Mingw

Question

我尝试使用 MSYS2 和 MIngW 从源代码编译 FFmpeg 我使用的是 win7 64 bit 。
使用 。

$ ./configure --enable-shared

我收到此错误:

Unknown OS 'msys_nt-6.1'.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

查看 config.log
我看到(日志的结尾):

gcc -std=c99 -Wall -O3 -c -o /tmp/ffconf.fnJeLuIu.o /tmp/ffconf.e8DJYGJM.c

我错过了什么 ？我做错了什么 ？
谢谢

你应该用visual studio编译它，你必须安装msys2和yasm ..
将以下选项添加到 ./configure :

--工具链=msvc\
--arch=x86\
--启用-yasm\
--启用-asm\
--启用共享\
--禁用静态

检查这个网站，他给出了一些解释:
