When trying to compile FFmpeg under FreeBSD 8.1-RELEASE I got an error: {{{ Error: `ff_h264_cabac_tables+1024+128(%esi)' is not a valid 64 bit base/index expression }}} apparently the linker is broken, but as seen [http://blogs.everycity.co.uk/alasdair/2009/05/ffmpeg-64bit-x86_64-amd64-on-solaris-10/ here] there is a workaround. After the {{{./configure}}} phase apply: {{{ echo '#define BROKEN_RELOCATIONS 1' >> config.h }}}
