I've compiled ffmpeg with ports-gcc, and all is working
as expected. The performance is much better than disabling
neon with llvm. I strongly recommend you to change the port
to use gcc on this arch.

Not really surprised.  I figure it's because we require strict
alignment but the whole ecosystem didn't evolve with that in mind...

ffmpeg on arm

[adr]

First of all, hello to everyone.

ffmpeg needs to be configured with --disable-fast-unaligned and
--disable-neon, or it will fail (and any application using libav)
with a bus error.

Also, I had to eliminate all the check-clean-src target from
the Makefile (the one of the source) of python (2.7 and 3.7)
to be able to compile it.

Tested in 6.5 and current, on armv7 (allwinner h3).

I've been using openbsd just for a few days, so I'll
let someone with more (any) experience to fixed it in the
best way.
