It seems to fix placing this in multimedia/libaom Makefile:
CMAKE_CONFIGURE_ARGS+= -DENABLE_NEON_DOTPROD=0
"NEON_DOTPROD" uses the Armv8.2-DotProd extension that is not supported
by the Cortex A72 cores in the rpi4.
libaom does have runtime checks to select appropriate code paths
for different Arm CPUs, but it is disabled in the package Makefile
for some reason:
.if !empty(MACHINE_PLATFORM:MNetBSD-*-*arm*) \
|| !empty(MACHINE_PLATFORM:MNetBSD-*-aarch64*) \
|| !empty(MACHINE_PLATFORM:MDarwin-*-aarch64)
CMAKE_CONFIGURE_ARGS+= -DCONFIG_RUNTIME_CPU_DETECT=0
.endif
Make that should be reviewed.
