Description Martin Jambor 2024-05-05 17:22:59 UTC 
Vlc fails when built with GCC 14 because of use incompatible pointer
types, which used to be warnings in previous versions of GCC but are
errors by default in GCC 14:  

https://build.opensuse.org/package/live_build_log/home:rguenther:plgrnd/vlc/openSUSE_Factory/x86_64

The bug seems to have been reported upstream as
  https://code.videolan.org/videolan/vlc/-/issues/28441
and to Gentoo as https://bugs.gentoo.org/919068.  but there is also
yet unresolved) Gentoo issue https://bugs.gentoo.org/919296 so the
particular error might not be the only one.

For more information on porting to gcc 14, see
https://gcc.gnu.org/gcc-14/porting_to.html
Comment 1 Dominique Leuenberger 2024-05-14 15:15:29 UTC 
Added upstream MR 4645 onto the package.


This contains:

Subject: [PATCH 1/5] input: fix incompatible-pointer-types assignment
Subject: [PATCH 2/5] yadif: fix variable type
Subject: [PATCH 3/5] swscale: avoid invalid pointer conversion
Subject: [PATCH 4/5] dynamicoverlay: fix variable shadowing
Subject: [PATCH 5/5] dynamicoverlay: fix memory corruption

Build is still to passing on GCC14 yet, but we're getting closer at least
