VLC fails to build with x265-4.0

Hey folks! While working on upgrading Beyond Linux From Scratch to x265-4.0, we're encountering a build failure in VLC.

codec/x265.c: In function ‘Encode’:
codec/x265.c:92:43: error: passing argument 5 of ‘x265_encoder_encode’ from incompatible pointer type [-Wincompatible-pointer-types]

This is VLC 3.0.21 with GCC 14.2.0. The build issue is related to the API changes described at https://mailman.videolan.org/pipermail/x265-devel/2024-September/013945.html

Note that if you build this with a previous version of GCC (such as GCC 13), VLC will build correctly, but crash at runtime.
