1368843 - libaom doesn't build for android

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, enhancement, P3)

Description

[Ralph Giles (:rillian)]

The libaom (av1 reference implementation) code doesn't build on arm-linux-android.

Like with libvpx, it has some arm assembly we have to convert to an llvm-assembler-acceptable format before we can pass it to the compiler. We could add support for this in a Makefile.in (like libvpx) or by adding hooks to mozbuild's GENERATED_FILES object.

However, upstream has indicated that they'd like to move away from assembly in favour of compiler intrinsics for neon, since portability of those has improved to a useful state. I've done some work toward removing the assembly entirely upstream but some functions still need to be converted. So this is a little more work, but nicer going forward.
