Summary of the bug:
When building ffmpeg 7.1.1 from source on macosx x86-64 and selecting only h264
one can observe a linker error around __ff_aop_uninit_film_grain_params
Undefined symbols for architecture arm64:
"_ff_aom_uninit_film_grain_params", referenced from:
_ff_h2645_sei_reset in h2645_sei.o
ld: symbol(s) not found for architecture arm64
How to reproduce:
configure ffmpeg 7.1.1 for H.264 only, like
--enable-shared --disable-static --disable-programs --disable-doc
--disable-everything --enable-decoder=h264 --enable-parser=h264 --disable-bzlib
--disable-iconv --disable-lzma --disable-xlib --disable-zlib --disable-libxcb
--disable-vaapi
