The commit actually uses #ifdef blocks, but I still get an error when compiling with MACOSX_DEPLOYMENT_TARGET=10.13
I suspect that there was an oversight or does ffmpeg really require a minimum version of macOS 12? I also understand that both 10.13 and 12.x are long out of support. I am not against raising the minimum level, but I just want to make sure that it is absolutely necessary. In the past something similar happened and it turned out that the code was missing another ifdef block.
Here's the error for reference: --------libavdevice/avfoundation.m:896:38: error: 'kIOMainPortDefault' is only available on macOS 12.0 or newer [-Werror,-Wunguarded-availability-new]
