Can't compile FFmpeg on Mac from latest Git version

[Paul Pacifico]

With the latest git version I cannot compile FFmpeg on x86 and arm Mac computers.

Here is my build configuration:

PKG_CONFIG_PATH="$BUILDS/lib/pkgconfig" \
CFLAGS="-I$BUILDS/include -fno-stack-check -mmacosx-version-min=10.13" \
LDFLAGS="-L$BUILDS/lib -mmacosx-version-min=10.13"

./configure --cc=/usr/bin/clang --prefix=$BUILDS \
		--extra-cflags="-framework openAL" \
		--extra-ldflags="-framework openAL" \
		--ld="g++" \
		--pkg-config-flags="--static" \
		--extra-ldexeflags="-Bstatic" \
		--shlibdir="@loader_path" \
		--disable-static \

		--enable-libgsm \
		--enable-libsvtav1 \
		--enable-libaom \
		--enable-appkit \
		--enable-avfoundation \
		--enable-coreimage \
		--enable-audiotoolbox

I get this error:

libavutil/hwcontext_videotoolbox.c:592:39: error: implicit declaration of function 'CVBufferCopyAttachments' is invalid in C99 [-Werror,-Wimplicit-function-declaration]

CFDictionaryRef attachments = CVBufferCopyAttachments(pixbuf, kCVAttachmentMode_ShouldPropagate);

It works when using

-mmacosx-version-min=12.0

It seems related to ​this change

So we can't build FFmpeg using videotoolbox with a lower version than OSX 12.0?

Working on a fix for this.

Just curious, which SDK version were you using?

You can check with xcrun --sdk macosx --show-sdk-version

It has been fixed:
​https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/2fc37c42391a38bfe0aea248f2fe75c9033f98e5

I'm using SDK version 10.14.
