Probably yes.

Maybe the constification can be a separate patch? Or does it depend on
the conversion?

Hi Anton,
Nice to see your work on race/UB removal.
I have been working on removing races from libavcodec/pthread_frame.c
as part of a wider effort to remove TSan-detected races from Firefox,
which uses ffmpeg-3.0.2. This is tracked starting at
https://bugzilla.mozilla.org/show_bug.cgi?id=127425

AV_WN64 is meant for unaligned data, but the existing av_alias* unions
(without a definition for the av_alias attribute - we don't have one
for MSVC) indicate to the compiler that they would have sufficient
alignment for normal access, i.e. the compiler is free to assume
8 byte alignment.
