[MPlayer-users] -ac hwac3 crashes in FreeBSD

Wed Oct 16 20:41:08 CEST 2002

-ac hwac3 seems to have broken at some point in FreeBSD, I get a segfault in af_format.c.
Works ok in Linux.

- MPlayer crashed by bad usage of CPU/FPU/RAM. Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and disassembly. For details, see DOCS/bugreports.html section 5.b.
- MPlayer crashed. This shouldn't happen. It can be a bug in the MPlayer code _or_ in your drivers _or_ in your gcc version. If you think it's MPlayer's fault, please read DOCS/bugreports.html and follow instructions there. We can't and won't help unless you provide these informations when reporting a possible bug.
