Notably they are exchanged between demux and decode thread. It's fine because we know those pointers will be alive as long as avctx is alive. And only the value may change during decoding in rare situations. Make those pointers atomic for the sake of it. It shouldn't change anything, except some codegen. From https://www.gnu.org/software/libc/manual/html_node/Atomic-Types.html#Atomic-Types: In practice, you can assume that int is atomic. You can also assume that pointer types are atomic; that is very convenient. Both of these assumptions are true on all of the machines that the GNU C Library supports and on all POSIX systems we know of.
