https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D260432 --- Comment #1 from Jan Beich <jbeich@FreeBSD.org> --- Does standalone lame encoding work fine? If so rebuild ffmpeg with debug symbols but leave optimization enabled then get a backtrace and disassemble= the crashing instruction. For example, $ export CFLAGS=3D-g STRIP=3D STRIP_CMD=3Dtrue $ make clean all deinstall install DEBUG_CONFIGURE_OFF=3D"--disable-debug --disable-stripping" $ lldb -- `which ffmpeg` -i renamed.aac renamed.mp3 (lldb) run (lldb) bt (lldb) dis Also extract CPU description/features from dmesg output. It's going to be necessary to compare the crashing instruction against what your CPU really supports. --=20 You are receiving this mail because: You are the assignee for the bug.=
