请大佬帮忙看一下，这是我的电脑环境没配对，还是需要手动改一下指针类型？

找到do-compile-ffmpeg.sh 这个文件，

FFMPEG_CFLAGS=
FFMPEG_CFLAGS="$FFMPEG_CFLAGS -arch $FF_ARCH"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FF_XCRUN_OSVERSION"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FFMPEG_EXTRA_CFLAGS"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FF_XCODE_BITCODE"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS -Wno-error=incompatible-function-pointer-types" # 加上这个就能编译过了

我试了一下是可以的

找到do-compile-ffmpeg.sh 这个文件，

FFMPEG_CFLAGS=
FFMPEG_CFLAGS="$FFMPEG_CFLAGS -arch $FF_ARCH"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FF_XCRUN_OSVERSION"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FFMPEG_EXTRA_CFLAGS"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FF_XCODE_BITCODE"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS -Wno-error=incompatible-function-pointer-types" # 加上这个就能编译过了

我加了之后，也没有用，还是报错。

To add on, after adding -Wno-error=incompatible-function-pointer-types, I also faced some more errors related to int-conversion.

So you might also want to add -Wno-int-conversion:

FFMPEG_CFLAGS="$FFMPEG_CFLAGS -Wno-error=incompatible-function-pointer-types -Wno-int-conversion"

#FFMPEG_CFLAGS=
#FFMPEG_CFLAGS="$FFMPEG_CFLAGS -arch $FF_ARCH"
#FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FF_XCRUN_OSVERSION"
#FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FFMPEG_EXTRA_CFLAGS"
#FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FF_XCODE_BITCODE"
#FFMPEG_LDFLAGS="$FFMPEG_CFLAGS"

FFMPEG_CFLAGS=
FFMPEG_CFLAGS="$FFMPEG_CFLAGS -arch $FF_ARCH"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FF_XCRUN_OSVERSION"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FFMPEG_EXTRA_CFLAGS"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS $FF_XCODE_BITCODE"
FFMPEG_CFLAGS="$FFMPEG_CFLAGS -Wno-error=incompatible-function-pointer-types" # 加上这个就能编译过了
FFMPEG_LDFLAGS="$FFMPEG_CFLAGS"
FFMPEG_DEP_LIBS=

这样改就可，我试过了

-Wno-error=
改成这个就好了
FFMPEG_CFLAGS="$FFMPEG_CFLAGS -Wno-incompatible-function-pointer-types"
