New description:

 Compilation of port ffmpeg fails if macport build_arch is i386 (on a
 x86_64 machine):
 It is not a C error, but a gcc asm problem;  " ‘asm’ operand has
 impossible constraints " (i don't remember which file, but it was in
 libavcodec).

 To fix this, I added
 {{{
 --enable-yasm
 }}}
 to the list of configure.args in the Portfile of ffmpeg.

 Of course, yasm should also be added as a dependency to ffmpeg. I would
 recommend to enable yasm for all architecture (no need to make different
 behavior between 32 and 64 bits).

 Thanks for the good work with macports !
